ST789

st789Tutorial shows how to interface Arduino with ST7789 TFT. An IPS display uses SPI protocol and has 240x240 pixel resolution. Arduino ST7789.Snificantly 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.
