hello,
I’m currently building a board for my simucube and I would like to use more than 14 buttons. so the usage of the pin 7 would help me. however I’m getting strange behavior when I press the buttons. some of them are getting the same number. maybe I did not understood the meaning of this pin 7 utilization…
can somebody please confirm the following usage. this is how I have understood it. could be good but maybe not!
without pin7 as shift
connector pin +PIN7 button
x12 upper 1 no 1
x12 upper 2 no 2
x12 upper 3 no 3
