i working on video project
vga 640x480 mode @ 60hz (thanks smaffer , nick gammon inspiration)
using uno (or nano) @ standard 16mhz speed
probably looking @ 200 pixels across , whatever looks vertically
i have worked out 3 font sizes 33 chars per line (not using spi bit bashing)
and pretty sure can 131,072 colours on screen @ once
i have worked out timings , there small amount written in c, written in asm option speed
the intention have vga display of dmx512 data (250kbps) magnificent bar-chart
its crazy can out of avr !!
