Overview

This Mini control board is designed for quick and easy assembly of a smart car. To support more high-power motors, it features a wide voltage input (15~36V), uses a MOSFET-based full-bridge driver, and includes an onboard MPU6050 (six-axis accelerometer), CAN transceiver, buzzer, DIP switches, and other basic components. It also provides reserved serial and CAN interfaces for external communication via FPC cables, and can supply power externally (5V 2A) via the same cables.
This project involves three boards; currently, only the debug board and the 36V control board have been verified.
Verification includes:
motor forward/reverse speed control √
motor speed measurement √
serial communication √
buzzer, LED √
DIP switches √
(CAN and MPU6050 have not yet been tested, but they should be 90% reliable – confidence!!!)
While writing the driver code, my thinking became too active, and I veered off-topic, porting the cmd command-line functionality to the board. I will improve the software later when I have time, and also post a short xcmd porting guide.

Phase shift algorithm implemented in DSP
This article is from HELLODSP. I saw a friend asking how to achieve phase shift in DSP. I thought that the software implementation method should be simpler than the hardware implementation, and it can
