wemos tft display free sample

We know the display will work when stacked onto an MHT-Live ESP32 but as delivered that shield (TFT plus I2C) has no connection for example between TFT_RST and either D1, D3 or D4, you have to choose, similarly for CD and LED. To help clarify, check it out with a DVM where e.g. RST is going, there are solder pads on the rear to choose with a solder bridge.

The touchscreen is a shield that mounts on arduino, not on Wemos. If you selected Wemos for wifi communications then you"ll have to get both arduino and wemos, and connect them (examples in the forum).

The ESP8266 is a well performing microcontroller chip that is fully Arduino compatible. Its WiFi capability makes boards with this chip easy implementable as IOT devices. Here we wire two representative ESP8266 boards: NodeMCU and Wemos D1 mini to a single-row 14-pin header, 320*240 TFT display that uses the four-wire SPI interface.

Here we connect a 320240 ILI9341 TFT display that has a SPI pin-out. This breakout board has 3.3V controller logic while power supply and background illumination operate on either 3.3V and 5V. ESP8266 microcontroller boards support displays with up to 320480 pixels

The display shown in figure 1 has a touch screen. It has a single row of 14 pins (figure 1; see also figure 3). The pins supporting ‘touch’ as well as those associated with the SD card reader are not connected: we concentrate on displaying text, variables, graphics and fast sequences of memory-loaded bitmaps (‘image frames”). The ILI9341 controller is fast and, in combination with an ESP8266, performs excellently.

The sketch uses the “Adafruit_GFX.h” and “Adafruit_ILI9341.h” libraries. This requires a constructor with defined CS, RST and DC pins. The ‘Clock’ (SCK) pin of the display is connected to pin D5 and the ‘DATA’ (MOSI) pin is wired to pin D7.

Figure 3 shows a Wemos D1 mini board mounted on a prototyping breadboard together with a 2.8 inch ILI9341 SPI TFT display according to the wiring diagram shown in Figure 2. The ESP8266 is running a demo adapted for the “Adafruit_GFX.h” and “Adafruit_ILI9341.h” libraries from Bodmer’s ‘Clock’ example for his TFT_eSPI library.

— ESP8266_ILI9341_Adafruit_Bodmers_clock.ino, a real time analog clock example adapted from Bodmer’s TFT_eSPi library examples (display visible in figure 3).

Needs some wiring. This shield can"t be used directly on Wemos D1, because two pins are duplicated to the Arduino connectors: D5 is SCK and digital 5, D6 is MISO and digital 6.

The ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins, it’s low cost and easy to use.

This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel, this means it has 57600 pixels. This module works with 3.3V only and it doesn’t support 5V.

The ST7789 display module shown in project circuit diagram has 7 pins: (from right to left): GND (ground), VCC, SCL (serial clock), SDA (serial data), RES (reset), DC (or D/C: data/command) and BLK (back light).

The first library is a driver for the ST7789 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “st7789” and install the one from Adafruit).

As you all know the are a few variants of the 1.8" TFT on the internet. With the genuine Adafruit lcd-s there are usually no problems. But when using fake ones(usually from Aliexpress) you have to make some adjustments.

Bodmers TFT_eSPI library is very awsome and rich funcionality. And the best part is that he made it to handle the pixel offsets depending on wich kind of 1.8" TFT you are using.

Then uncomment the tft height an width. And then in my case(REDTAB) uncomment for eg: #define ST7735_REDTAB. After this save it for the moment and compile sketch and upload to board. To be sure i have defined the parameters in the sketch too.This is a bit long procedure, cause you have to compile and upload the sketch every time to board untill the offset is gone, but it is worth the experimenting. For editing the h. files i strongly suggest Wordpad. Images included.

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.

I"m using an Arduino-like WeMos D1 and a TFT LCD shield on it. When I want to run a sample program like graphictest, it does not compile the program and it gives me these errors:

I wanted to try these ST7735 inexpensive displays that can be found all over the internet, so I ordered a couple for a few euros each. My quick research showed that a number of libraries support them and it turns out that you can display anything you want. Of course, we are not talking about playing modern games on it or watching 4k videos. These are just simple displays that can be really helpful to any project.

And here is how the TFT looks. As you see it also has a port for an SD card if you want to use e.g. for reading images from it. In my case, I didn’t connect it.

Once you have the connections ready next step is to install the TFT library in your Arduino IDE. Go to Tools – > Manage Libraries and then search for TFT_eSPI and click install. Alternatively, crab the lib from here.

After this, you can pick any of the examples from the library to upload to your ESP32 microcontroller. Some of them are really nice. For testing, I connected a DHT11 temperature/humidity sensor and I displayed the readings in the ST7735. Sweet!

I’ve chose not to remove the SD card slot and attach the enclosed Wemos D1 Mini Pro using a connector instead of soldering directly. It will allow for future replacements and adding another shield, where I want to plant some basic temperature/humidity sensor (possibly remotely connected). The board does not leave much pins free, however more devices can be easily chained through I2C bus.

What you’ll build in less that 20 minutes of soldering is a device, that (with demo sketch for Arduino IDE) is able to connect to your WiFi and fetch current WeatherStation data for pre-defined location. On first start, it will require to calibrate touch display used to control the device.

The Arduino sketch has 438k built so there’s still plenty of room to add more features. However, I’m looking to dive deeply into existing example code in order to reuse as much as possible. There’s NNTP, visual WiFi display, display carousel, icons, fonts, colours and last but not least the touch screen support.

The ESP32 touch sensor development kit, ESP32-Sense Kit, is used for evaluating and developing ESP32 touch sensor system. ESP32-Sense Kit consists of one motherboard and multiple daughterboards. The motherboard contains a display unit, a main control unit and a debug unit. The daughterboards have touch electrodes in different combinations or shapes, such as linear slider, wheel slider, matrix buttons and spring buttons, depending on the application scenarios. Users can design and add their own daughterboards for special usage cases.

TFT Touch Shield V2.0 is a resistive touch screen, compatible with Arduino/Seeeduino/Arduino Mega/SAMD21 platforms. It can be used as display device or sketch pad. Compared with the previous version, 2.8""TFT Touch Shield V1.0, we upgraded the screen driver to a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version are needed for modification before being transplanted to the new version. With a SD card module integrated on this shield, this shield reserves capability for other expansions of your project.

We recommend using Seeed_Arduino_LCD with internal flash chips larger than 128k. If you have a smaller flash device, I recommend using the TFT_Touch_Shield_V2.
