Hi,
I just bought my first Matrix Orbital LCD display (LK204-25) and grayhill keypad 4x4.
The display is working great,but I cannot get the keypad to work.
I connect the keypad to the display, then the display goes to my BS2 (Tx, Rx, GND).
My BS2 only received decimal 0 or 255 when I pressed any key.
Instead of using keypad, I have also tried to short the keypad connector on display board using jumper wire. It didn't work also.
Pls help me...
Thanks,
Bronson Alex
