Megacell Regular Firmware Update - State Machine - Major Upgrade - Mega CNC

This firmware is mandatory if you plan to use Mega CNC opensource software. It will work with all megacell chargers pre-pro version, until 3D - Printed version. The version with 3D Printed shrouds needs some work and I want to know if there are still users using those and want to upgrade to Mega CNC.
Thanks for your support and I hope you find this change as an improvement!

Hello,
what is the type of the ADC used on the Megacel Regular charger board? I have broken my charger by connecting 12V as the power supply instead of 5V by mistake. I replaced and flashed the ESP (it was also dead) but now it does not detect all of the I2C devices on the bus and the ADC seems the only thing missing.
