Measurement of PWM parameters by using Python

[Giri Prasad N]

Hi,

 

I need to measure PWM parameters by using python scripting. I am using Analog Discovery. I have tried the script "AnalogIn_Acquisition.py", provided by digilent. I am able to get the sample data and plot the graph, also able to calculate average and Maximum Voltages. I am unable to get the parameters such as Duty Cycle and Frequency. I have used different APIs provided in the reference document but, I am unable to read the parameters. Please help me to read those parameters. Please let me know, if any additional information is needed.

 

Thanks & regards,

Giri Prasad N.

Hi @Giri Prasad N,

I have moved your question to a more appropriate section of the Forum where an engineer much more familiar with the python scripting will be able to see and respond to your question.

Thanks,

Hi @Giri Prasad N

The WaveForms application provides an user interface with a set of processing, measurements, views...
You can use the Script interface to automate tasks, logging with java-script. You can also use scripts to create custom math, measurements...

The WaveForms SDK provides low level functions to control and capture data from the device.
The data processing and measurements needs to be done in your custom application.
