I own a picade 10 inch arcade box, and upgraded it at the end of February with 10-Plasma-buttons. After installing them, I found out that 2 of the 10 PCBs did not work correctly (some of the LEDs did not function) and one of the cables had some issue too, all the PCBs after the defective cable did light up only 1 LED in a random color…
so i replied to the reseller, and he kindly sent me a new set of Plasma Buttons.
now I have the problem, that the last LED in the complete chain always reacts with a delay, or does even nothing.
for example, when I set plasmctl 64 64 64, all buttons light up white, when I switch to plasmactl 0 0 0 - then all lights go out, except the last LED in the chain - it always remains blue… sometimes, after a while it goes out too, sometimes it keeps lighting blue. (I’ve uploaded a small video of the “effect”)
I already was spending hours in changing every single cable and every single PCB and trying different combinations, but the behavior stays the same. so I’m running out of ideas… could possibly the picadeHAT itself be the problem?
I’m using a raspberry Pi4 with an original raspberry power-supply,
the latest version of Raspbian and RetroPie.
thank you very much for your help,
