Nice explanation. The clue to measuring the vsys on the pico W is to use the cyw43_thread_enter() and cyw43_thread_exit() functions/macros around the ADC sampling to make sure the SPI traffic with the wifi chip is not interfering. This example was a result of my issue 1222 were the solution was provided by the RPI pico team members peterharperuk and kiligraham, which resulted in the merged pull request 331 (which links to issue 1222)
Excellent video, very useful! I was precisely designing a power module for my course project. Thanks for your efforts, keep going!
Good timing. Good luck with course and project.
