Power monitoring part 2

Wall-e wouldn’t be Wall-e without his screen; it’s a critical part of his character!

We’ve had the screen working with test programs over SPI for a while but one of our voltage sensors was a dud. That meant we hadn’t been able to get the iconic “CHARGE LEVEL” screen working in full.

Today I swapped out the voltage sensor and added a screen update loop to the code.

Then all of a sudden there’s Wall-e! He feels real now!
