[MCU] Add a basic Human to Machine Interface for the user
During hackathon in Paris, valid argument have been made regarding the current rudimentary human to machine interface (HMI) of the power converter.
Minimal interface should include according to Romain's expertise:
- A mechanical switch that permit to enable/disable the power to flow through the power stage. The switch should permit to see at a glance if the power is enabled or disabled.
- 2 LEDS - One to see if the MCU is stucked or performing correctly (could already be the status LED) - One for power (Already implemented IMHO)
- 2 Push buttons - To be able to change the voltage reference or other parameters.
- 1 Potentiometer - To be able to change the reference or other parameters.
