I am trying to get my head around the button matrix.My problem seems to be when I add another row. Only 1 encoder works and 1 works on one button only. Are there set pins for rows and columns and do they need to be used in a certain order?
kuabi buttons are dynamically numbered sequentially. first goes button maxtrix(BM). second - shift registers(SR).
so if you earlier had BM 1*8, SR bind starts from "9" position. when you increase BM to 2*8, SR goes to "17" position. more, BM reading algorytm: loop_for_colunms set column to high state loop_for_rows read row state end_loop_rows clear column high state end_loop_columns
every time when you change button's sources you are need to reset encoder/joystick buttons.
