Library keypad 4x4 1 wire (update)


#1

I made my first library https://xod.io/libs/cesars/keypad-4x4-1wire/, I think it works. I would like you to try it and if you think it can be improved

Thank you, but unfortunately it does not work as I want.
If I compare fixed values yes, but take the values of the port

I have corrected something, but by serial port I keep seeing 0Fh :roll_eyes:

Edit:
I found the flaws :slightly_smiling_face:
1- I was missing map Greater and less nodes
2 - put an AND and instead went a bitwise-xor
