Hi
with Dmitry's help, our keyboard is work.
we use the matrix_keypad.c driver. I found a problem.
for example. the keypad is like this: (part of keypad)
GPIO GPIO GPIO
| | |
a_______w_______u_____GPIO
| | |
|_______s_______j_____GPIO
| | |
Shift___Alt_____Ctrl__GPIO
first time press [Shift] + [a] it's output [a] not the [A]
second time press [Shift] + [a] it's output [A]. correct.
then all work fine. but when I release the [Shift]. and press [a]
it's will also output big [A]. but if the midifier and character not
in same column GPIO. it will work fine.
other modifier all like this. same GPIO will cause problem.
I should look into the matrix_keypad.c to fix this, right?
Best Regards
