Description
This firmware package for the 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.
