#144115 - Isn't it all in the (row, col) addressing? Responding to: ???'s previous message |
ie, can't you just consider a 2x20 display to be a 4x20 with the bottom 2 lines missing?
So that would make it easy for your "top half" 2x20 display; the "bottom half" would have to translate the row addresses... Jecksons Ben said:
How's about using MC4066 switch or MUX Not if it is, indeed, a matter of adjusting the addressing... |
