Using STM32's Hardware SPI to drive a ST7789 based IPS display.

• 135*240 resolution
• 240*240 resolution

If you like, you could customize it's resolution to drive different displays you prefer.

For example, a 240x320 display is perfectly suited for st7789.
Just set all X_SHIFT and Y_SHIFT to 0, and set resolution to 240|320.

For more details, please refer to ST7789's datasheet.

Include st7789.h in main.c for a simple test, you could refer ST7789_Test() function in while(1).
Don't forget to refer ST7789_Init(); before you use any functions...

This code has been tested on 240x240 IPS screen. You can look into demo directory for details.

Test conditions:

• STM32F103C8T6
• Keil MDK5

Some display won't work, you should consider adding a pull-up resistor on SCLK(SCK) and SDA(MOSI) pin.

The simplest way is to configure these 2 GPIO to Pull-up Mode manually in CubeMX(if supported) or in SPI initialization code.
