/**
* LCD for Melzi v4 needs a custom cable with reversed GND/5V pins; plugging in a standard cable may damage the board or LCD!
* 1. Swap the LCD's +5V (Pin2) and GND (Pin1) wires. (This is the critical part!)
* 2. Swap pin 4 on the Melzi LCD to pin 7 on the SKR Mini E3 EXP1 connector (pin 4 on the SKR is a RESET and cannot be used)
