ESP32 as a logic analyzer.
Posted: Wed Dec 20, 2017 10:49 am
By using sigrok and implementing the SUMP protocol over serial I was able to use the ESP32 as a logical analyzer.
Quite a nice way to get a better understanding of the streams of bits running over the wires of the ESP32.

Here is the source.

Does not yet work with Open Bench Logic sniffer but that will be the next step if this project sparks interest.

Another improvement would be using parallel i2s input with DMA to get a higher and smother sampling rate.
