STM32 Blue Pill HSPI1 and ST7735 128x160 TFT LCD

I have a 1.8 inches 128x160 TFT display module from Ali-Express years ago. It uses the ST7735 controller. It's very popular with Arduino board. This LCD module is available from many manufacturers with the ST7735 LCD controller or its compatible. However we can use other MCU to interface with this LCD via its 4-wire SPI interface. Most of manufacturers of this LCD module have datasheet and example code for various micro-controllers for instance, lcdwiki.com or buydisplay.com.


 

I found some sample code from those manufacturers that was written in C that can be ported to many MCU with some code modification. However I want to use an STM32 Blue Pill I posses due to their popularity, high speed and their rich of peripheral.
