mini cluster of ESP32

https://raw.githubusercontent.com/Wei1234c/Broccoli/master/jpgs/Broccoli_cluster_cover.gif Hi, I wrote a package with which you can dispatch tasks to an ESP32 cluster in a Celery-Canvas fashion. For an ESP32 to function as a cluster node, it needs two sets of code (in the order of uploading to ESP3...

Re: How to use scipy in micropython

FFT is so important for signal processing and many other usages, also ESP32 has ADC and DAC.

It will be very nice if FFT is built into MicroPython.

Re: IPython Parallel, Hub-Workers, MicroPython and ESP8266

ANN example is to show that an IoT network can be configured dynamically and the ANN becomes autonomous. Not very pratical, due to ESP8266's small memory .
