Neat! ESP32s run FreeRTOS natively, but this looks like it might be running on their Arduino stack.

A great idea. Could use a nice flashy GUI like Saleae protocol analyzers.

The Arduino stack on esp32 is still freertos.
That's why it's recommended to leave the loop() empty, and run tasks (or whatever) in the setup() and have the tasks do their own loop
