Introduction

Because the recent research on some punctual atomic codes requires experiments with official screens, but the official screen modules are too expensive. So I drew a low-cost compatible module myself.

This module is perfectly compatible with Zhengdian Atom's official [MCU screen: resistive screen] Zhengdian Atom 2.8-inch TFT LCD module touch LCD screen display STM32 screen module, and can be used directly in Zhengdian Atom's STM32 series development boards.

characteristic

• 100% compatibility, directly run the official example of Punctual Atom without any modification to the code.
• (Optional) Extract TE signal for vertical synchronization function.
• (Optional) Added constant current backlight system, which can extend the life of the LCD panel

make

After welding according to the components in the BOM, it can be used normally. If optional extended functionality is required, please refer to the notes in the schematic yourself.
