Hello fellow zynthian owners ,
I have checked almost everything in my piece, but not the snapshot button. The encoder and button are soldered properly (have put it on CTRL-4 and it worked fine) but when connected to CTRL-3 it works just as encoder, not as button.
Were should I start to find out my mistake ?
Also in the process probably ruined the wire to the screen (started glitching, gone white etc.) - my bad. Will find the replacement for these ide cable.
