This lovely little display breakout is the best way to add a small, colorful and bright display to any project. Since the display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available!

The 1.8" display has 128x160 color pixels. Unlike the low cost "Nokia 6110" and similar LCD displays, which are CSTN type and thus have poor color and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 18-bit color (262,144 shades!). And the LCD will always come with the same driver chip so there"s no worries that your code will not work from one to the other.

The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card. The microSD card is not included, but you can pick one up here.

Of course, Adafruit wouldn"t just leave you with a datasheet and a "good luck!" - they havewritten a full open source graphics library that can draw pixels, lines, rectangles, circles, text and bitmaps as well as example code and a wiring tutorial. The code is written for Arduino but can be easily ported to your favorite microcontroller!

This lovely little shield is the best way to add a small, colorful and bright display to any project. We took our popular 1.8" TFT breakout board and remixed it into an Arduino shield complete with microSD card slot and a 5-way joystick navigation switch (with a nice plastic knob)! Since the display uses only 4 pins to communicate and has its own pixel-addressable frame buffer, it can be used easily to add a display & interface without exhausting the memory or pins.

The shield has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so its safe to use with 5V Arduinos. We also had some space left over so we placed a microSD card holder (so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card) and a 5-way navigation switch (left, right, up, down, select). The microSD card is not included.

If you just want to display text, shapes, lines, pixels, etc the shield uses pins 13, 11, 10 and 8. If you"d like to add the navigation switch, it uses Analog 3 (all 5 switches are connected using a clever resistor trick to permit all the switches to share one analog pin). For the microSD card, you"ll also give up Digital 12 and 4. This shield works best with the Arduino UNO and compatibles. You can use it with the Mega but it won"t be as fast since it would be using software rather than hardware SPI for both the TFT and SD card, so it"s not recommended.

Comes as a fully assembled and tested shield with the display, microsd card holder and nav switch with knob as well as a stick of 0.1" header. To finish up and use, you will need to solder on the header onto the shield PCB, a quick 10 minute task.

Display current draw is mostly based on the backlight, with full backlight the current draw is 100mA, this does not *include the SD Card. SD cards can draw 20-100mA based on read/write. Measure current draw in circuit to get precise numbers.

In the above example, Node32-Lite and this 1.8-inch LCD.  Please refer to the tutorial here: ST7735S interfacing with ESP32 to make the connections, Arduino library installation, and modification needed for it to works on this LCD.

Adafruit took their popular 1.8" TFT breakout board and remixed it into an Arduino shield complete with microSD card slot and a 5-way joystick navigation switch and three selection buttons! Since the display uses only 4 pins to communicate and has its own pixel-addressable frame buffer, it can be used easily to add a display & interface without exhausting the memory or pins.

New! Adafruit have updated this shield to be "Arduino R3" format compatible so you can now use it with any and all Arduinos or Metros - including the Metro M0 or M4, Arduino Mega, Zero, etc. They also use Adafruit seesaw for the TFT backlight, TFT reset, and button inputs - you can query the buttons and joystick over I2C now, so only 2 pins are needed to communicate with all 8 switches.

The shield has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as a ultra-low-dropout 3.3V regulator and a 3/5V level shifter so its safe to use with 3V or 5V Arduino compatibles. Adafruit also had some space left over so they placed a microSD card holder (so you can easily load full color bitmaps from a FAT16/FAT32 formatted microSD card), a 5-way navigation switch (left, right, up, down, select) and three tactile buttons marked A BC. The microSD card is not included.

If you just want to display text, shapes, lines, pixels, etc the shield uses the SPI pins (SCK/MOSI/MISO), I2C pins (SDA & SCL) and digital #8. For the microSD card, you"ll also give up Digital #4. This shield works with any Arduino UNO and compatibles, Mega, Zero, etc. If it"s shield compatible, you"re good to go.

The display is driven by a ST7735R controller ( ST7735R-specifications.pdf (2.1 MB) ), can be used in a “slow” and a “fast” write mode, and is 3.3V/5V compatible.

Adafruit_ST7735 is the library we need to pair with the graphics library for hardware specific functions of the ST7735 TFT Display/SD-Card controller.

In the file dialog select the downloaded ZIP file and your library will be installed automatically. This will automatically install the library for you (requires Arduino 1.0.5 or newer). Restarting your Arduino software is recommended as it will make the examples visible in the examples menu.

The easiest way to remedy this is by extracting the GitHub ZIP file. Place the files in a directory with the proper library name (Adafruit_GFX, Adafruit_ST7735 or SD) and zip the folder (Adafruit_GFX, Adafruit_ST7735.zip, SD.zip). Now the Arduino software can read and install the library automatically for you.

Basically, besides the obvious backlight, we tell the controller first what we are talking to with the CS pins. CS(TFT) selects data to be for the Display, and CS(SD) to set data for the SD-Card. Data is written to the selected device through SDA (display) or MOSI (SD-Card). Data is read from the SD-Card through MISO.

So when using both display and SD-Card, and utilizing the Adafruit libraries with a SainSmart display, you will need to connect SDA to MOSI, and SCL to SCLK.

As mentioned before, the display has a SLOW and a FAST mode, each serving it’s own purpose. Do some experiments with both speeds to determine which one works for your application. Of course, the need of particular Arduino pins plays a role in this decision as well …

Note: Adafruit displays can have different colored tabs on the transparent label on your display. You might need to adapt your code if your display shows a little odd shift. I noticed that my SainSmart display (gree tab) behaves best with the code for the black tab – try them out to see which one works best for yours.

Low Speed display is about 1/5 of the speed of High Speed display, which makes it only suitable for particular purposes, but at least the SPI pins of the Arduino are available.

After connecting the display in Low Speed configuration, you can load the first example from the Arduino Software (“File” “Example” “Adafruit_ST7735” –  recommend starting with the “graphictest“).

Below the code parts for a LOW SPEED display (pay attention to the highlighted lines) – keep in mind that the names of the pins in the code are based on the Adafruit display:

The SD-Card needs to be FAT-16 or FAT-32 formatted, single partition, and the BMP file needs to be placed in the root (ie. not in a directory or anything like that).

You can name your BMP file “parrot.bmp” or modify the Sketch to have the proper filename (in “spitftbitmap” line 70, and in “soft_spitftbitmap” line 74).

#define SD_CS 4 // Chip select line for SD card#define TFT_CS 10 // Chip select line for TFT display#define TFT_DC 9 // Data/command line for TFT#define TFT_RST 8 // Reset line for TFT (or connect to +5V)

#define SD_CS 4 // Chip select line for SD card#define TFT_CS 10 // Chip select line for TFT display#define TFT_DC 9 // Data/command line for TFT#define TFT_RST 8 // Reset line for TFT (or connect to +5V)

To use this in your Arduino Sketch: The first 2 characters represent RED, the second set of two characters is for GREEN and the last 2 characters represent BLUE. Add ‘0x’ in front of each of these hex values when using them (‘0x’ designates a hexadecimal value).

This function is used to indicate what corner of your display is considered (0,0), which in essence rotates the coordinate system 0, 90, 180 or 270 degrees.

However, if your application needs your screen sideways, then you’d want to rotate the screen 90 degrees, effectively changing the display from a 128×160 pixel (WxH) screen to a 160×128 pixel display. Valid values are: 0 (0 degrees), 1 (90 degrees), 2 (180 degrees) and 3 (270 degrees).

Based on these functions, I did create a little demo to show what these functions do. Either download the file or just copy the code and paste it into an empty Arduino Sketch.

The SparkFun TFT LCD Breakout is a versatile, colorful, and easy way to experiment with graphics or create a user interface for your project. With a 4-wire SPI interface and microSD card holder, you can use this breakout to easily add visual display/interface capabilities to a project as well as providing all the storage you might need for multimedia files.

To get started with this breakout, you will need an Arduino compatible microcontroller of your choice - we recommend something with extra RAM like the SparkFun Thing Plus. The breakout can be powered with either 5V or 3.3V. The microSD card holder is connected to the same SPI bus as the display which keeps the required pin count low and exists to relieve the burden from your microcontroller"s poor memory due to having to store hundreds of images of cats, or really whatever you want to keep there. We have also gone ahead and tricked out the SparkFun HyperDisplay library with a driver made especially for this breakout!

Out of the box, the SparkFun TFT LCD Breakout will come with a large backing PCB that makes it easy to securely mount the display in a project. If you need a more flexible solution you can remove the display module, snap off half the backing board, and then re-insert the display module. When this is done you"ll be left with the bare minimum frame around the display to more seamlessly integrate with your project.

So I just got the Adafruit 1.8" TFT display and i wired it up to my OSEPP UNO rR3 Plus and all im getting is a white screen, ive been dozens of forums and websites trying different things but nothing seems to be working, I must have rewired the thing a million times but it still wont work. I"m still a little green to arduino so I"m thinking maybe its my programming abilities but the I don"t know of the arduino examples could be that wrong.

I do know that the screen is getting some kind of signal because the data wires/pins can make a LED blink and flicker so if anyone has experience with this or has any ideas I"d love the assist thanks
