ST7789 fast SPI library optimized for 16MHz AVR Arduino
Fast SPI library for the ST7789 240x240 IPS display
Significantly optimized for 16MHz AVR Arduino boards (2.5-5x faster than other libraries)
Achieved 6.9Mbps SPI transfer rate (at DIV2/16MHz clock)
Connections for displays without CS pin (only 6 wires required):
#01 GND - GND
#02 VCC - VCC (3.3V only!)
#03 SCL - D13/SCK
#04 SDA - D11/MOSI
#05 RES - D8 or any digital
#06 DC - D7 or any digital
#07 BLK - NC
The code:
