We were just talking about getting system info into graphs in the comments in a previous blog entry – and I realised I already had some code for getting that info in Python – and using a library that can provide a LOT more.
So – as it was there already - I thought I’d put this quick entry together for anyone interested.

Flush with success at writing trivial code on NEO platform to control lights and displays, in Python, I thought I’d have a go at microPython on the ESP8266 and the ESP32.
Getting this working on the ESP8266 was trivial as the binary files start at zero – so really you just have to use your favourite tool to flash the chip (this is not the place to teach anyone how to flash chips incidentally).
I grabbed the binary file for the ESP8266 from here and set my usual programming software to start at location 0, rebooted the board, hooked up a serial interface at 115KBaud and pressed reset.
