ESP32-S3 Parallel 3.5'' TFT with Touch

Introduction

We know that the ESP32-S2 Parallel 3.5'' TFT doesn't have Bluetooth, which can make it lose some functions for short-range communication. But if we choose the ESP32 3.5" TFT Touch with Camera, some customers feedback they want a higher speed display. So we can't give up its high refresh rate for use., with the esp32-s3 published, we choose it as the main control IC to diver the TFT display.

That is why we publish this latest ESP32-S3 Parallel TFT, compares to the S2 version, not only more SRAM and ROM, the Bluetooth 5.0 make it fit for applications such as local monitoring/controlling.

This ESP32-S3 is configured 3.5" 320x480 TFT LCD to driver ILI9488, it uses 16bits parallel line for communication with ESP32-S3, the main clock could be up to 20MHz, making the display smooth enough for video displays. With this display, you can freely create more IoT display projects.

If you not install CP2104 driver on your PC, install CP2104 driver first CP210x Driver.

Software

To ensure the running environment, the same version is recommended.

1.Install the Arduino IDE V1.8.19.

2.Install the ESP32 boards supporting V2.0.5

Note: Different PC has different Serial COM number

Touch_keyboard_v2 demo

In this demo, ESP32-S3 Parallel 3.5'' TFT with Touch as a USB HID to display the function of the keyboard.

So you can get the code from GitHub.

Then open the file*touch_keyvborad_V2*.

In the code, you must modify as your own WiFi-Configuration

So, we can look at this video as an example which is show the effect of ESP32-S3 Parallel 3.5" TFT with Touch as a USB HID.

About the refresh rate

Sure we know it's the best advantage is the refresh rate. Compared with ESP32-S3 SPI 3.5" TFT with Touch, It can exhibit a faster refresh rate. Now you can find out through the video below.

About the LVGL

LVGL open source graphics library is a hot point in the development board with screen. Through development, we can design our own GUI. we will show an example as follows.

The open source code provide from @radiosound-com:https://github.com/radiosound-com/mak...

FAQ

You can list your question here or contact support@makerfabs.com for technology support. Detailed descriptions of your question will be helped to solve your question.

  • Q: Why the display fails to respond sometimes I touch?
  • A: The touching interface is loose, please reconnect it.
