This firmware package for STEVAL-ESC001V1 board implements sensorless field oriented control (FOC) for drone electronic speed controller (ESC). It includes auto restart functionality when the motor stalls (e.g., blocked propeller) and the ESC arming/disarming safety measure.
The STSW-ESC001V1 firmware package is composed of three parts (see User manual UM2200): the Motor Control firmware for the STEVAL-ESC001V1, the PC software plug-in to manipulate STEVAL-ESC001V1 parameters with the ST Motor Profiler, and the project file suited for the ST Motor Control Workbench (STSW-STM32100).
A sensorless FOC algorithm drives the motor, and the firmware accepts commands from most common flight control units through PWM signals; developers can also exploit CAN, UART or I²C communication through the relative connectors on the STEVAL-ESC001V1 board.
The plug-in for the ST Motor Profiler offers real time motor parameter information to help you quickly get your drone flying.
