I just finished the first Version of the Firmware. It isn't pretty by any means but it shows the basic functionality working.

I currently only show 3 readouts:

• supply voltage
• current drawn
• power

there is currently only one mode so I use the mode switch to flip the display.

As I said the firmware only shows a proof of concept of the functions and the used libraries to proof a working PCB to the judges of the square inch contest. More functionality is planned (e.g. graphing of current, power, voltage, all together?)

But thats all for now folks.
