ST7789 tft display C library

[Wiaz]

Hi, I try to connect a tft 240x240 display via SPI with my BPI m2zero and i am looking for a suitable library written in C. The display uses ST7789 driver and it will be used in combination with thermal camera. I've tried to use producers library for RPi https://www.waveshare.com/wiki/1.54inch_LCD_Module but the screen only blinks when i run a program with test bitmap. I tested it on Arduino and the display works fine. If someone was able to run such a display, can you share your library? Thanks for all the help
