Just a small comment, I found your article confusing, as it seems you are saying there are only 4 GPO's on the unit when there are 8 pairs of +12+gnd? Or have I grabbed the wrong end of the stick?
Sort of. Basically there are 8 GPOS each outputting 12+ but they are actually only four. Because they are all paired up. So if I turn off gpo 1, the first 4 pin (2 pairs) turn off.
You CANNOT control all 8 independently
So I look forward to all this being included in lcdc 1.0 !!!!
