Clever idea! :clap:_

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:

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
