What setup is required for the LED Panel PMOD? Specifically:
Which way does the panel ribbon cable connector go? Looks like the notched side faces the the middle of the board.
Is the 5v/gnd two-wire connection between the iCEBreaker board and the LED panel PMOD board necessary? I see that scanlime used it in her video (~00:57), saying it’s for driving level shifters. But if it’s like other driver boards I’ve seen, it could be needed only if you want to power the LED panel from the ICEEBreaker board. So if you use a proper 5v/4A supply directly to the panel, then you don’t need the 5v/gnd two wire connection?

Scanlime also changes a PCB jumper labeled “Output IO Voltage Select,” setting it to 5V (~01:33). What did that do? Again, is that necessary if you’re powering the LED panel from directly from its own power supply?
In the LED panel PMOD revision I received with the kit. 1.2c, there are additional X0, X1 lines. What are they?
- Is there a way to test the setup? Some quick test before writing HDL? Perhaps some precompiled demo code and a shell command or script that loads it?
