STC ESC

Overview

This project uses an ESC (Electronic Speed Controller) designed with STC series chips to prepare for a future intelligent vehicle competition.
The solution used is a modified version of an ESC solution from the STC forum, using the STC32G12K64 as the main controller. The original project link is provided below: BLDC, Three-phase Brushless DC Motor Driver - STC8/STC32 - Hallless, 120,000 RPM, Video Tutorial - BLDC/144MHz - PWM - Hardware Phase Shifting/45-channel PWM + 3-channel CCP/7 groups of PWM with different cycles/DAC.
The control algorithm uses FOC (Flatform Open Circuit).
A serial port is provided on the board for downloading programs and can also be used for communication later.
It supports medium-power brushless motors.
