So far, we have created two display implementations for Mecrisp Forth: a 128x64 OLED display, connected via (overclocked) I2C, and a 320x240 colour LCD, connected via hardware SPI clocked to 9 MHz. While quite usable, these displays are not terribly snappy:
the OLED display driver uses a 1 KB ram buffer, which it sends in full to the OLED whenever “display” is called - this currently requires about 60 milliseconds
