st789Snificantly optimized for 16MHz AVR Arduino boards (2.5-5x faster than other libraries). Achieved 6.9Mbps SPI transfer rate (at DIV216MHz clock) In compatiliblity mode it could work with other MCUs, but I didn't test it.ST7789VW Datasheet Sitronix reserves the rht to change the contents in this document without prior notice, please contact Sitronix to obtain the latest
