STC-FOC Lite

This is a simplified version of FOC (Focus on the Controller) without current feedback. Currently, it's compatible with 280x series motors, using the STC32F12K54 as the main controller. It's low-cost, integrates the driver, and is very compact.
Different screw interfaces can be transposed using 3D-printed parts
for control signals: it supports I2C high-speed mode, PPM pulse width control, single-wire serial port control, and 0~5V analog signals (I2C mode is recommended).
The mode cannot be switched after power-on; it's only achieved by switching different receiver programs.
Control methods: Supports speed control and position control modes, but no torque control. Avoid stalling; stalling will lock the duty cycle upper limit to prevent excessive current from burning out the motor.
