I am having some trouble with my keypad. I build my code, then use PICUSB to write the
hex file. The busy light comes on, then when it turns off, I switch from PRG to RUN.
However, my keypad does not work at this point. At one point in my code, I am prompted
to enter how many balls I want to dispense in Can1. But when I press a key on the
keypad, it does not show up, and the program does not proceed.
However, if I switch back to PRG, turn the board OFF, turn it back ON, and switch to RUN,
the program runs as expected and the keypad is fully functional.
I thought it may be a problem with my code, but when I test the Keypad hex file from the
sample code given, the same issue arises.
This problem only started happening today. Up until this point, I did not have this
problem. I think it may be a problem with the keypad itself, but really I have no idea.
