esp32 tft display library for sale

This module is the 3.2” version of the ESP32 touchscreen display, based on ESP32-WROVER, with a built-in 2M pixel OV2640 camera. The LCD is 320x240 TFT, with driver is ILI9341, it uses SPI for communication with ESP32, the SPI main clock could be up to 60M~80M, make the display smooth enough for videos; and the camera OV2640 with pixel 2M, with this camera, you can make applications such as remote photography, face recognition…

While the camera not used, you can freely use all these pins with the breakout connectors, to connect the ESP32 display with sensors/ actuators, suitable for IoT applications.

It is a PCB design to be used with most of the LCD screens out there, the recommended library for controlling the screen es TFT_eSPI, you can use any of these screens:

I did it because some times or most of the time when you buy an LCD screen for your project, there is no available pcb design around it, and it makes your project to become a mess of cables, with this board you get a solid platform to continue working on no matter the display you have

If you need the ESP32 already soldered, just let me know. The board does not include the serial port to be connected directly to your USB, it does however contains the pinout for you to hook your external programmer. If you also want external port included, again, let me know,

ESP32 TouchDown is complete solution for anyone who wants/needs an ESP32 with capacitive touchscreen. It also has battery management onboard, a piezo speaker, and an SD card reader. ESP32 TouchDown works out of the box with the Arduino IDE, providing you have installed the ESP32 Arduino Core. Pins that are not used by the peripherals onboard are broken out.

The ESP32 TouchDown is designed with FreeTouchDeck (https://github.com/DustinWatts/FreeTouchDeck) in mind. The ESP32 TouchDown is the one stop solution to get a FreeTouchDeck up and running with capacitive touch without the need to buy separate modules. ESP32 TouchDown"s are shipped to you with the most current release of FreeTouchDeck installed! Off course you can always re-flash it with your own firmware.

The ESP32 TouchDown can be used for more the FreeTouchDeck alone. It is a fully featured DevKit. In the Github repository you will find some examples to get you started:

The ESP32 TouchDown can run of a Li-Po battery. Combined with WiFi and BLE this makes the ESP32 TouchDown very portable. It uses an MCP73831 Charge Management Controller set to a charge current of 330mA. Charging is done through the USB-C port (using 5V). The on/off switch doesn"t effect the battery charging. So even when the ESP2 TouchDown is off, you can still charge the battery. When the ESP32 TouchDown is plugged in to USB, it will use USB power over battery power and will switch to battery power when USB is disconnected, without interrupting the ESP32.

Although the bare board looks great (if I do say so myself), there is a design for a nice slick case available on the Github repository. There are a few different backs to support a case without battery, with battery, and a FreeTouchDeck style case. You can find the case here: https://github.com/DustinWatts/esp32-touchdown/tree/main/Case

The TFT backlight anode (positive supply) is selectable via a jumper on the back. You can either power it directly from 3.3V or use GPIO32 (this will add dimming support). By default, the positive source is GPIO32. On V1.1 Of the board the jumpers that are used are with bridged pads. So if you want to change the backlight power source, you will have to cut the trace and add a blob of solder bridging the other pads. You can revert back to the original configuration by adding a blob of solder to the pads where the trace was cut.

The capacitive touch controller is a FocalTech FT6236 (datasheet). The FT6236 uses I2C and has address 0X38. I made an Arduino IDE library available here: https://github.com/DustinWatts/FT6236.

Note: from batch 2 forward the FT6206 touch controller is used. This controller works the same and has the same I2C only a different Chip ID. The library above also support the FT6202.

ESP32 TouchDown comes ready to use. It includes all features that you would need additional modules for when using a development board. Besides that, ESP32 TouchDown is fully open source. All hardware designs can be found in the Github repository. ESP32 TouchDown is also OSHWA cerftified. You can find more information here: https://certification.oshwa.org/nl000004.html

We"ve written 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.

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 that you can use it with 3.3V or 5V power and TTL control logic.

This board works fine with TFT_eSPI when the ST7789 driver is selected. The pin settings are different and the RGB colour order is reversed compared to other boards so I have added an option to the TFT_eSPI library to set the colour order.

I have set the SPI rate to 80MHz and the ST7789 TFT seems to work perfectly at that clock speed, the higher clock frequency boosts the drawing speed (e.g. clear screen in 18ms as opposed to 33.3ms).

The Grove I2C connector is not soldered in, this is clearly because the pins would poke through the board and damage the back of the display. It would be possible to "surface mount" the connector by bending the pins but I think the solder flowing into the PTH may melt the reflective backlight diffuser screen at the back of the display. One way around this would be to fill the holes with epoxy first.

I was using directly this TFT screen on a Wemos ESP32 board and with the 3 wires hardware mod i got sucess and the image start appearing on this screen. At the beguinning mirrored and after a lot of searches i found the correct drive for my TFT is the below one:

To make your library work with my TFT i need to force the usage of #define ST7735_DRIVER but changing the dimenstions to 480*320 because with any other i always got the image mirrored :( I don"t know if you know the reason for this, but according what i search seems to be the need of having the "INVERT_SS" command of init.

Testing with your libraries the touch funcionality i got first the error "TFT_eSPI" has no member named "getTouch"". I have uncomented the line #define TOUCH_CS 21, but i"m not sure if the port number is correct. Where I can find this port? And my TFT use paralell ports, so i got after the same error as mentioned above about the spi ports.

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.
