Hey thanks, I have a mild understanding of how it works sorta but there are a lot of signals flying around. D0-D3 tell the display which Ys to light for the current X at every CL2 cycle but how does it know which X it is on? The timing chart is a little confusing there. What does the FLM do? I assume CL1 and CL2 are clock pulses and it says CL1 is roughly 20 MHz (52.1-59.5 us) .

Does anyone have any experience, code, or schematics that might help me start?
