Hello GHI friends,
I need to poll 20 buttons to check if a button has been pressed.
Polling speed is important (need to detect at most 2 buttons pressed / second)
I plan to write an RLP looping routine to poll each button for a state change.
When a button’s state changes, I will exit the RLP loop, service the request, and then re-enter the RLP routine and continue polling.
I’d appreciate knowing if there is a better approach to detecting a state change in 20 buttons.
Thanks for the great products and excellent support!
