Measuring a PWM (500Hz) signal with python sdk

[diodo93]

Hi!

I have a Discovery3 and I'm trying to measure a PWM signal (500 Hz) with python. I took a look at the examples but I didn't manage to do it (mainly DigitalDiscovery_RecordToFile.py).

Basically, I'm using the digital pin 0 (DIN 0) connect to my PCB which generates a PWM signal up to 1600Hz. 

I'm a little bit desperate because I can do it easily with the GUI, but with python I can't even record the signal in a bin or csv file and it seems to be a simple thing.

Thank you so much for your help.

Hi @diodo93

As the name should suggest the "DigitalDiscovery_RecordToFile.py" is an example for the Digital Discovery and not Analog Discovery.
See the DigitalIn_Acquisition.py DigitalIn_Trigger.py ... examples
