Base plate for Laowang’s 2.6-yuan 2.0-inch 9225-driven parallel LCD screen

Overview

Used for the screen on Lao Wang’s house a few days ago

The parallel port used by this thing can be 8-bit or 16-bit, selected through resistors. The resolution is 176*220, the display effect is average, the screen is at 12 o'clock, and both the screens I clicked on have flaws.

I made the board in a bit of a hurry and forgot to drill the copper pillar holes. The schematic and PCB were modified later.

Attached is a program using the STM32F407 FSMC peripheral driver: https://github.com/kaidegit/LCDDrv4ATK2.8/tree/ILI9225_OldFive

The original project was drawn by AD and is also placed in this github project.

---------------Following updates----------

According to the tips from the smoking boss, I modified the initialization code and changed the initialization to write 0x1B41 to 0x1038 in the 0x11 register and it will display normally.
