Hi
now the keypad in Ben NanoNote[1] is work.
problem is I don't know how to write the special assemble key of matrix_key driver. some kind of 'SHIFT', like the red key in [2].
when I press the 'RED UP POINT' + 'W' = '@'
attach is the Ben keypad driver platform.c:260 ~ 364 lines.
thanks for any advice
