Hi Noek,
thanks for the help.
I tried it in the first way. I wired everything as seen on samplerbox.org. And I adjust the code as you mentioned and set the values on "True".
When I start, the sounds from Folder "0" are loading. I can play them. The display is off. Its starts much later (I guess thats normal?!).
When I press "+" or "-" nothing happens. It is still red and showing "0000".
I did not tried it in the second way. Because I wasn't able to find the wiring diagram on github. Maybe you can share a link.
I checked with a multimeter. The idea came up in my head that the wiring is worng, because... to be honest... the wireing diagram on samplerbox.org is done wiht "Windows paint".
But everything seems to work. The Display has voltage. (obviously...). The buttons are having unpressed "infinity resistance" and when pressed "no resistance". I compared again with the GPIO sheet from RP3B+ so that I am 100% sure that I connected to the right GPIO Pins (17 and 18, as mentioned) are the 6th Pins, counted from the top down.
So no mistake here. I mean I can "solder" it again. But I measured the resistance from Button to GPIO and its going thorugh. So no idea.
So I try to do it again with your second way. When I found the picture. Or any other ideas?
Best regards,
Ari
