I bought the Picade X HAT and have built an arcade cabinet with illuminated buttons. Everything functions correctly except the buttons only stay illuminated for a brief period after the initial start up. Is there a way to have them constantly illuminated while the Pi is powered on? I currently have them wired into the LED + and - terminals.
If yes, you need to use the plasma connector, and load the plasma software.
If no, you need to wire them up to either the 3.3V pin and ground.
Or the +5V and ground if they are safe to use at 5V.
That was it, perfect! I’m using cheap Chinese buttons so it was just a case of moving the wiring to the 3.3v pin. Thanks!
That’s good to hear. They will be brighter on 5V, providing they are rated for use at 5V.
