stm32 blue pill wires with 1.8 tft lcd display free sample

An excellent new compatible library is available which can render TrueType fonts on a TFT screen (or into a sprite). This has been developed by takkaO and is available here. I have been reluctant to support yet another font format but this is an amazing library which is very easy to use. It provides access to compact font files, with fully scaleable anti-aliased glyphs. Left, middle and right justified text can also be printed to the screen. I have added TFT_eSPI specific examples to the OpenFontRender library and tested on RP2040 and ESP32 processors, however the ESP8266 does not have sufficient RAM. Here is a demo screen where a single 12kbyte font file binary was used to render fully anti-aliased glyphs of gradually increasing size on a 320x480 TFT screen:

The TFT configuration (user setup) can now be included inside an Arduino IDE sketch providing the instructions in the example Generic->Sketch_with_tft_setup are followed. See ReadMe tab in that sketch for the instructions. If the setup is not in the sketch then the library settings will be used. This means that "per project" configurations are possible without modifying the library setup files. Please note that ALL the other examples in the library will use the library settings unless they are adapted and the "tft_setup.h" header file included. Note: there are issues with this approach, #2007 proposes an alternative method.

Support has been added in v2.4.70 for the RP2040 with 16 bit parallel displays. This has been tested and the screen update performance is very good (4ms to clear 320 x 480 screen with HC8357C). The use of the RP2040 PIO makes it easy to change the write cycle timing for different displays. DMA with 16 bit transfers is also supported.

Support for the ESP32-S2, ESP32-S3 and ESP32-C3 has been added (DMA not supported at the moment). Tested with v2.0.3 RC1 of the ESP32 board package. Example setups:

Smooth fonts can now be rendered direct to the TFT with very little flicker for quickly changing values. This is achieved by a line-by-line and block-by-block update of the glyph area without drawing pixels twice. This is a "breaking" change for some sketches because a new true/false parameter is needed to render the background. The default is false if the parameter is missing, Examples:

New anti-aliased graphics functions to draw lines, wedge shaped lines, circles and rounded rectangles. Examples are included. Examples have also been added to display PNG compressed images (note: requires ~40kbytes RAM).

Frank Boesing has created an extension library for TFT_eSPI that allows a large range of ready-built fonts to be used. Frank"s library (adapted to permit rendering in sprites as well as TFT) can be downloaded here. More than 3300 additional Fonts are available here. The TFT_eSPI_ext library contains examples that demonstrate the use of the fonts.

Users of PowerPoint experienced with running macros may be interested in the pptm sketch generator here, this converts graphics and tables drawn in PowerPoint slides into an Arduino sketch that renders the graphics on a 480x320 TFT. This is based on VB macros created by Kris Kasprzak here.

The RP2040 8 bit parallel interface uses the PIO. The PIO now manages the "setWindow" and "block fill" actions, releasing the processor for other tasks when areas of the screen are being filled with a colour. The PIO can optionally be used for SPI interface displays if #define RP2040_PIO_SPI is put in the setup file. Touch screens and pixel read operations are not supported when the PIO interface is used.

DMA can now be used with the Raspberry Pi Pico (RP2040) when used with both 8 bit parallel and 16 bit colour SPI displays. See "Bouncy_Circles" sketch.

The library now supports the Raspberry Pi Pico with both the official Arduino board package and the one provided by Earle Philhower. The setup file "Setup60_RP2040_ILI9341.h" has been used for tests with an ILI9341 display. At the moment only SPI interface displays have been tested. SPI port 0 is the default but SPI port 1 can be specifed in the setup file if those SPI pins are used.

The library now provides a "viewport" capability. See "Viewport_Demo" and "Viewport_graphicstest" examples. When a viewport is defined graphics will only appear within that window. The coordinate datum by default moves to the top left corner of the viewport, but can optionally remain at top left corner of TFT. The GUIslice library will make use of this feature to speed up the rendering of GUI objects (see #769).

An Arduino IDE compatible graphics and fonts library for 32 bit processors. The library is targeted at 32 bit processors, it has been performance optimised for STM32, ESP8266 and ESP32 types. The library can be loaded using the Arduino IDE"s Library Manager. Direct Memory Access (DMA) can be used with the ESP32, RP2040 and STM32 processors with SPI interface displays to improve rendering performance. DMA with a parallel interface is only supported with the RP2040.

For other processors the generic only SPI interface displays are supported and slower non-optimised standard Arduino SPI functions are used by the library.

"Four wire" SPI and 8 bit parallel interfaces are supported. Due to lack of GPIO pins the 8 bit parallel interface is NOT supported on the ESP8266. 8 bit parallel interface TFTs (e.g. UNO format mcufriend shields) can used with the STM32 Nucleo 64/144 range or the UNO format ESP32 (see below for ESP32).

The library supports some TFT displays designed for the Raspberry Pi (RPi) that are based on a ILI9486 or ST7796 driver chip with a 480 x 320 pixel screen. The ILI9486 RPi display must be of the Waveshare design and use a 16 bit serial interface based on the 74HC04, 74HC4040 and 2 x 74HC4094 logic chips. Note that due to design variations between these displays not all RPi displays will work with this library, so purchasing a RPi display of these types solely for use with this library is not recommended.

A "good" RPi display is the MHS-4.0 inch Display-B type ST7796 which provides good performance. This has a dedicated controller and can be clocked at up to 80MHz with the ESP32 (55MHz with STM32 and 40MHz with ESP8266). The MHS-3.5 inch RPi ILI9486 based display is also supported.

Some displays permit the internal TFT screen RAM to be read, a few of the examples use this feature. The TFT_Screen_Capture example allows full screens to be captured and sent to a PC, this is handy to create program documentation.

The library supports Waveshare 2 and 3 colour ePaper displays using full frame buffers. This addition is relatively immature and thus only one example has been provided.

The library includes a "Sprite" class, this enables flicker free updates of complex graphics. Direct writes to the TFT with graphics functions are still available, so existing sketches do not need to be changed.

A Sprite is notionally an invisible graphics screen that is kept in the processors RAM. Graphics can be drawn into the Sprite just as they can be drawn directly to the screen. Once the Sprite is completed it can be plotted onto the screen in any position. If there is sufficient RAM then the Sprite can be the same size as the screen and used as a frame buffer. Sprites by default use 16 bit colours, the bit depth can be set to 8 bits (256 colours) , or 1 bit (any 2 colours) to reduce the RAM needed. On an ESP8266 the largest 16 bit colour Sprite that can be created is about 160x128 pixels, this consumes 40Kbytes of RAM. On an ESP32 the workspace RAM is more limited than the datasheet implies so a 16 bit colour Sprite is limited to about 200x200 pixels (~80Kbytes), an 8 bit sprite to 320x240 pixels (~76kbytes). A 1 bit per pixel Sprite requires only 9600 bytes for a full 320 x 240 screen buffer, this is ideal for supporting use with 2 colour bitmap fonts.

One or more sprites can be created, a sprite can be any pixel width and height, limited only by available RAM. The RAM needed for a 16 bit colour depth Sprite is (2 x width x height) bytes, for a Sprite with 8 bit colour depth the RAM needed is (width x height) bytes. Sprites can be created and deleted dynamically as needed in the sketch, this means RAM can be freed up after the Sprite has been plotted on the screen, more RAM intensive WiFi based code can then be run and normal graphics operations still work.

Drawing graphics into a sprite is very fast, for those familiar with the Adafruit "graphicstest" example, this whole test completes in 18ms in a 160x128 sprite. Examples of sprite use can be found in the "examples/Sprite" folder.

The "Animated_dial" example shows how dials can be created using a rotated Sprite for the needle. To run this example the TFT interface must support reading from the screen RAM (not all do). The dial rim and scale is a jpeg image, created using a paint program.

The XPT2046 touch screen controller is supported for SPI based displays only. The SPI bus for the touch controller is shared with the TFT and only an additional chip select line is needed. This support will eventually be deprecated when a suitable touch screen library is available.

The library supports SPI overlap on the ESP8266 so the TFT screen can share MOSI, MISO and SCLK pins with the program FLASH, this frees up GPIO pins for other uses. Only one SPI device can be connected to the FLASH pins and the chips select for the TFT must be on pin D3 (GPIO0).

Configuration of the library font selections, pins used to interface with the TFT and other features is made by editing the User_Setup.h file in the library folder, or by selecting your own configuration in the "User_Setup_Selet,h" file. Fonts and features can easily be enabled/disabled by commenting out lines.

Anti-aliased (smooth) font files in "vlw" format are generated by the free Processing IDE using a sketch included in the library Tools folder. This sketch with the Processing IDE can be used to generate font files from your computer"s font set or any TrueType (.ttf) font, the font file can include any combination of 16 bit Unicode characters. This means Greek, Japanese and any other UCS-2 glyphs can be used. Character arrays and Strings in UTF-8 format are supported.

The .vlw files must be uploaded to the processors FLASH filing system (SPIFFS, LittleFS or SD card) for use. Alternatively the .vlw files can be converted to C arrays (see "Smooth Font -> FLASH_Array" examples) and stored directly in FLASH as part of the compile process. The array based approach is convenient, provides performance improvements and is suitable where: either use of a filing system is undesirable, or the processor type (e.g. STM32) does not support a FLASH based filing system.

It would be possible to compress the vlw font files but the rendering performance to a TFT is still good when storing the font file(s) in SPIFFS, LittleFS or FLASH arrays.

Anti-aliased fonts can also be drawn over a gradient background with a callback to fetch the background colour of each pixel. This pixel colour can be set by the gradient algorithm or by reading back the TFT screen memory (if reading the display is supported).

The common 8 bit "Mcufriend" shields are supported for the STM Nucleo 64/144 boards and ESP32 UNO style board. The STM32 "Blue/Black Pill" boards can also be used with 8 bit parallel displays.

Unfortunately the typical UNO/mcufriend TFT display board maps LCD_RD, LCD_CS and LCD_RST signals to the ESP32 analogue pins 35, 34 and 36 which are input only. To solve this I linked in the 3 spare pins IO15, IO33 and IO32 by adding wires to the bottom of the board as follows:

If the display board is fitted with a resistance based touch screen then this can be used by performing the modifications described here and the fork of the Adafruit library:

If you load a new copy of TFT_eSPI then it will overwrite your setups if they are kept within the TFT_eSPI folder. One way around this is to create a new folder in your Arduino library folder called "TFT_eSPI_Setups". You then place your custom setup.h files in there. After an upgrade simply edit the User_Setup_Select.h file to point to your custom setup file e.g.:

You must make sure only one setup file is called. In the custom setup file I add the file path as a commented out first line that can be cut and pasted back into the upgraded User_Setup_Select.h file. The ../ at the start of the path means go up one directory level. Clearly you could use different file paths or directory names as long as it does not clash with another library or folder name.

The library was intended to support only TFT displays but using a Sprite as a 1 bit per pixel screen buffer permits support for the Waveshare 2 and 3 colour SPI ePaper displays. This addition to the library is experimental and only one example is provided. Further examples will be added.

In this project, we will take a quick look at the STM32F103C8T6 Development Board, which is based on an ARM Cortex-M3 Microcontroller from STMicroelectronics. I will show you some important features of this board, how to configure your existing Arduino environment to work with this board and also write the first program, which is nothing but, yes, you guessed it, a Blinky. So, let’s get started.

An alternative to Arduino is the STM32F103C8T6 microcontroller-based development board, which is often called as the Blue Pill (Matrix reference). This microcontroller is based on ARM Cortex-M3 Architecture manufactured by STMicroelectronics.

STM32F103C8T6 is a very powerful Microcontroller and with its 32-bit CPU, it can easily beat Arduino UNO in performance. As an added bonus, you can easily program this board using your Arduino IDE (although with some tweaks and additional programmer i.e. USB to U(S)ART converter).

The following image shows the front and back sides of a typical STM32 Blue Pill Board. As you can see, the layout of the board is very simple and some might even confuse it for an Arduino Nano.

An important thing about these boards is that they are very cheap, cheaper than the cloned version of Arduino UNO. I got this board for approximately $2.5 (₹180) in my local electronics store. So, it is obviously a cloned version (probably a counterfeit STM32 MCU?) and there are many cloned versions of the board available in the market.

Coming to the Blue Pill board itself, you get the board and two male header strips for you to solder on to the board (shame that they don’t came pre-soldered).

On either long edge of the board, there are pins for connecting various Analog and Digital IO and Power related stuff. The following image shows the pin configuration of the board along with different functions supported by each pin.

As you can from the above image, each pin of the STM32F103C8T6 MCU can have multiple functions (but only one has to be selected). Also, note that some IO pins are 5V tolerant, which means that you can connect 5V compatible IO on those pins without any worry.

If you are planning to buy the cheaper version (which probably most of us will), then there are some known issues with the boards that you have to be aware of. I have taken these issues from various forums and faced some problems (USB related) myself.

The first main issue is the 3.3V regulator. Though some boards have used genuine LM1117 3.3V regulators from TI, most of the cheap development board are found with small, knock-off regulators from an unknown manufacturer. These regulators do not have any thermal protection and are easily damaged. The solution is to use an external regulated power supply, if you have the option.

The other issue related to USB is the usage of wrong pull-up resistor. According to the reference manual of the MCU, the USB D+ (named USBDP) must be pulled high to 3.3V using a 1.5KΩ resistor. But as per the schematics of several Blue Pill boards, all those are using a 10KΩ resistor. If you are planning to work on USB data transfer, then you might not get accurate results. If you are in desperate need for a solution, then you can solder a 1.8KΩ resistor is parallel to the existing 10KΩ resistor. For this, connect the 1.8KΩ resistor between pins A12 and 3.3V pin.

Now that we have seen a little bit about the Blue Pill Board, let us now understand some important features of the heart of the board i.e. the STM32F103C8T6 Microcontroller. As mentioned earlier, this MCU contain an ARM 32-bit Cortex – M3 CPU core with a maximum frequency of 72 MHz.

As a bonus topic, let me tell you the naming convention used in STM32 MCUs with the example of STM32F103C8T6. Each letter in the name of the MCU signifies a special characteristic.

Since this is our introduction part and all we will be doing is Blink an LED (which is already present on the board), we don’t need much hardware with respect to the project and the MCU.

But for programming the Microcontroller, we need a USB to Serial Converter Module, like an FTDI board (or anything similar). As mentioned in the BOOT Pins section, the bootloader can be accessed using USART1 pins of the Microcontroller to program the Flash Memory. And for the MCU to communicate with the USART1, we need a USB to Serial Converter.

If you already have some URLs in this section, you can add more by separating them with comma. If you have worked with ESP8266 Boards, then you might be familiar with this process already. After adding the URL, click on OK.

Now, go to Tools -> Board -> Board Manager… option and search for “stm32”. You will get a result like “STM32 Cores by STMicroelectronics”. Install the latest version. At the time of preparing this tutorial, the latest version is 1.8.0.

Now you can select the board from Tools -> Board -> Generic STM32F1 series. Once you select this board, a bunch of options will appear below for customizing your board type. The first important option is “Board part number”. Make sure that “BluePill F103C8” is selected.

The other important options are “U(S)ART support”, make it as “Enabled (generic ‘Serial’)” and “Upload method”, make its as “STM32CubeProgrammer (Serial)”. You can leave the remaining options as their default values.

In the above step, we have selected “STM32CubeProgrammer (Serial)” as the upload method but the problem is this tool is not downloaded and installed by the Boards Manager. So, we have to manually install it. For that, go to the official STM32CubeProgrammer download page provided by STMicroelectronics using the following link.

Click on Get Software option and it will take you Login/Register page. I suggest you to register with STMicroelectronics with a valid e-mail ID. Once you register, you can login and download the software.

A large zip file (approximately 164 MB for version 2.3.0) will be downloaded. Extract the zip file and you will get a Windows exe file with name “SetupSTM32CubeProgrammer-2.3.0”. Double click and proceed with installation.

Once the installation is complete, make sure that in the path “C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin” you have the “STM32_Programmer_CLI” exe file. If it is present, then you are good to go.

This completes the software setup for Arduino IDE to program STM32 Blue Pill. Let us proceed with writing a small program for blinking an LED and uploading it to our STM32F103C8T6 Blue Pill Board.

Make sure that you made the necessary changes to the Arduino IDE as mentioned in the previous section (selecting the correct board, etc.). Once that is done, make the connection between FTDI Programmer (i.e. USB to Serial Converter) and STM32 Board as mentioned before.

Now, before connecting the FTDI to the PC, make sure that STM32 Blue Pill Board is in “Programming Mode” i.e. connect the BOOT0 pin to HIGH. After that, connect the FTDI to the PC or Laptop. A COM port will be assigned to the programmer and select the same COM port in the Arduino IDE.

Once the compilation is successful, it will automatically invoke the STM32CubeProgrammer tool. If everything goes well, the IDE will successfully program the STM32 Board.

This was a lengthy tutorial on Getting Started with STM32 Blue Pill Board i.e. STM32F103C8T6. I have discussed some of the important features of the Board, highlights of the MCU, known issues of the board and how to fix them, configuring Arduino IDE, downloading necessary tools, writing our first program for STM32 on Arduino Ide and finally uploading the program and see the LED blink.

Since it’s inception the Arduino IDE has demonstrated the desire to support all kind of platforms, from Arduino clones and variations of different manufacturers to third party boards like the ESP32 and ESp8266. As more people get familiar with the IDE, they are beginning to support more boards that are not based on ATMEL chips and for today’s tutorial we will look on one of such boards. We will examine how to program the STM32 based, STM32F103C8T6 development board with the Arduino IDE.

The STM32 board to be used for this tutorial is none other than the STM32F103C8T6 chip based STM32F1 development board commonly referred to as “Blue Pill” in line with the blue color of its PCB. Blue Pill is powered by the powerful 32-bit STM32F103C8T6 ARM processor, clocked at 72MHz. The board operates on 3.3v logic levels but its GPIO pins have been tested to be 5v tolerant. While it does not come with WiFi or Bluetooth like the ESP32 and Arduino variants, it offers 20KB of RAM and 64KB of flash memory which makes it adequate for large projects. It also possesses 37 GPIO pins, 10 of which can be used for Analog sensors since they have ADC enabled, along with others which are enabled for SPI, I2C, CAN, UART, and DMA. For a board which costs around $3, you will agree with me that these are impressive specs. A summarized version of these specifications compared with that of an Arduino Uno is shown in the image below.

Based on the specs above, the frequency at which Blue pill operates is about 4.5 times higher than an Arduino UNO, for today’s tutorial, as an example on how to use the STM32F1 board, we will connect it to a 1.44″ TFT display and program it to calculate the “Pi” constant. We will note how long it took the board to obtain the value an compare it with the time it takes an Arduino Uno to perform the same task.

As mentioned earlier, we will connect the STM32F1 board to the1.8″ ST7735 based colored TFT Display along with a push button. The push button will be used to instruct the board to start the calculation.

Go over the connections once again to be sure everything is as it should be as it tends to get a little bit tricky. With this done, we proceed to set up the STM32 board to be programmed with the Arduino IDE.

As with most boards not made by Arduino, a bit of setup needs to be done before the board can be used with the Arduino IDE.  This involves installing the board file either via the Arduino Board manager or downloading from the internet and copy the files into the hardware folder. The Board Manager route is the less tedious one and since the STM32F1 is among the listed boards, we will go that route.

Start by adding the link for the STM32 board to the Arduino preference lists. Go to File -> Preferences, then enter this URL ( http://dan.drown.org/stm32duino/package_STM32duino_index.json ) in the box as indicated below and click ok.

The code will be written the same way we’d write any other sketch for an Arduino project, with the only difference being the way the pins are referenced.

To be able to easily develop the code for this project, we will use two libraries which are both modifications of standard Arduino Libraries to make them compatible for the STM32. We will use the modified version of the Adafruit GFX  and the Adafruit ST7735 libraries. Both libraries can be downloaded via the links attached to them.

With this done, we create an object of the ST7735 library which will be used to reference the display all through the entire project. We also indicate the pin of the STM32 to which the pushbutton is connected and create a variable to hold its state.

Next, we initialize serial communication and the screen, setting the background of the display to black and calling the printUI() function to display the interface.

We start by reading the state of the push button. If the button has been pressed, we remove the current message on the screen using the removePressKeyText() and draw the changing progress bar using the drawBar() function. We then call the start calculation function to obtain and display the value of Pi along with the time it took to calculate it.

The remaining part of the code are the functions called to achieve the tasks from drawing the bar to calculating the Pi. Most of these functions have been covered in several other tutorials that involve the use of the ST7735 display.

Uploading sketches to the STM32f1 is a little bit complex compared to standard Arduino compatible boards. To upload code to the board, we need an FTDI based, USB to Serial converter.

With this done, we then change the position of the board’s state jumper to position one (as shown in the gif below), so as to put the board in programming mode. Press the reset button on the board once after this and we are ready to upload the code.

With the code complete, follow the upload process described above to upload the code to your setup. You should see the display come up as shown in the Image below.

Press the pushbutton to start the calculation. You should see the progress bar slide gradually until the end. At the end of the process, the value of Pi is displayed along with the time which the calculation took.

Comparing these two values, we see that “Blue Pill” is over 7 times faster than the Arduino Uno. This makes it ideal for projects which involves heavy processing and time constraints. The small size of the Blue pill also serves as an advantage here as it is only a bit bigger than the Arduino nano and it can be used in place where the Nano won’t be fast enough.

That’s it for today’s tutorial guys. What will you be building with the Blue Pill? feel free to share along with any questions you might have, under the comment section.

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

Interfacing a 2.8 inch SPI TFT that has a ILI9341 chip to an Arduino Uno. 128x32 uses 0x3C address so this bit looks all good here, lets double check the header library, yes its also using the 0x3C address andthe display type is 128x32. - Now lets connect the 128x64 display. Now, you are ready to start experimenting with the Nextion display with Arduino UNO. We do not recommend using the SD card socket on this display. Next open Serial monitor from the icon on top right corner of Arduino IDE. I found it important to write this tutorial as if we see we find tutorial for 1.44, 1.8, 2.0, 2.4, 2.8 inch shields however there are no or less tutorials available for 3.5" shield as its completely different from other smaller tft lcd shields - The most common types are the basic directly connected displays, and the ones with I2C adapter. Connect the Arduino to computer. The display is a 2.8" colour TFT LCD screen with a ILI9341 controller, 320x240 pixels. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient. Based on the specs above, the frequency at which Blue pill operates is about 4.5 times higher than an Arduino UNO, for todays tutorial, as an example on how to use the STM32F1 board, we will connect it to a 1.44 TFT display and program it to calculate the Pi constant. Note, Arduinios use one serial port for communication with your PC, do not use this serial port for connection to your Nextion display, use a spare one. It does not work, but this hardware modification may be able to get it working. The other LCDs are similar. There are many types of LCD. Connect the Arduino to computer. WebIn this article, you will learn how to use TFT LCDs by Arduino boards. This will be a practical, simple arduino project. Its quiet easy to interface Arduino and 7 Segment display together! Arduino Mega 2256, 5 TFT display, Ver 1.2 Megashield, Arduino IDE 1.6.7. The function to display text on the LCD will be without a potentiometer & Resistor. We can also interface this LCD with only just 4 wires. Please ensure the correct port. Works with any classic Arduino "328. Now, you are ready to start experimenting with the Nextion display with Arduino UNO.

For todays tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5 Color TFT display with Arduino. What do you need? To connect the Arduino to the display module, I used voltage divider for each line which means there are 4 voltage dividers. 4.2.. You just need to make four connections: GND, RX, TX, and +5V. As a controller it has an Arduino UNO board, combined with a CNC shield and four A4988 stepper drivers. The function to display text on the LCD will be without a potentiometer & Resistor. Due to variation in display pin out from different manufacturers and for clarity, the pin connection between the Arduino and the TFT display is mapped out below: 1.8 TFT Arduino. Comparing the Blue Pill with Arduino Uno. - First we are going to load the code to an Arduino Nanoconnected to a 128x32 display. For this simple circuit we need to use an Arduino UNO (or any Arduino board), RTC DS1307 and NOKIA 5110 LCD. Interface 16x2 LCD (parallel interface) with Arduino Uno. MCUFRIEND_kbv library Adafruit TFT LCD library supports only small TFT displays. Draw shapes like circle, triangle, square, etc. But cannot have it running in my esp32 devkit v1 (following your instructions). The Visuino: https://www.visuino.eu also needs to be installed. The Visuino: https://www.visuino.eu also needs to be installed. The display has a parallel interface and when used with an Arduino UNO, uses almost all of the I/O pins, so if you want to also have other sensors connected, then you really need to use a Mega board.
