/**
 * HOW TO COMPILE
 *
 * PlatformIO - Use the STM32F401VE_STEVAL environment (or the "Auto Build Marlin" extension).
 *
 * Arduino - Tested with 1.8.10
 *      Install library per https://github.com/stm32duino/Arduino_Core_STM32
 *      Make the following selections under the TOOL menu in the Arduino IDE
 *          Board: "3D printer boards"
 *          Board part number: "STEVAL-3DP001V1"
 *          U(S)ART support: "Enabled (generic "Serial")"
 *          USB support (if available): "CDC (no generic "Serial")"
 *          Optimize: "Smallest (-Os default)"
 *          C Runtime Library: "newlib Nano (default)"
