Micropython Pyboard driving a 74HC595 Shift Register with SPI for Arduguitar

This is a little test of the pyboard from http://www.micropython.org driving some LEDs connected to a 74HC595 shift register using the micropython SPI library.

It was very easy to code this and debug it due to the interactive nature of python!  

What an improvement compared to  the C++ and the arduino environment!

The code with all the details is available at:
https://github.com/gratefulfrog/ArduGuitar/blob/master/Ardu2/design/POC-3_MAX395/pyboard/DraftDevt/spiTest.py

I later made a new version of  the code to run an arbitrary number of shift regs!
