Hello,
I have been using Arduino for a while but have recently been trying UIFlow.
Is there a way to measure the width of an input pulse on a GPIO input, similar to the Arduino pulsein() function?
Regards
Phil.

To use those micropython commands you could just paste them into an execute block in your code
