AC7811 Development Board Unboxing Report
https://bbs.21ic.com/icview-3068150-1-1.html
Upon receiving the board from the Autochips evaluation event, my first impression was: Oh, it’s a spliced board, the AutoChips logo is very prominent, with an MCU board and a motor driver board.
AC7811 Experimental Motor Introduction
https://bbs.21ic.com/icview-3071242-1-1.html
This experiment uses a BLDC motor removed from a hard drive, featuring an external rotor structure. BLDC stands for Brushless Direct Current, meaning it is a direct current motor without brushes; the external rotor indicates that its permanent magnet structure rotates externally.
Starting with MCU for Motor Control

The foundation of a motor is rotation. After thinking it over, why not add some flair to the rotation? One night while jogging, I saw a bicycle on the road with LED lights on the wheels forming colorful patterns during the ride. Later, I learned that this phenomenon called “persistence of vision” produces a toy called “spinning wheel.” So, I bought some WS2811s to see if I could create beautiful text during rotation.
Hands-On Testing of AC7811 Motor Driver Board
https://bbs.21ic.com/icview-3114434-1-1.html
This evaluation mainly consists of the following steps:
1. Understand the features of the development board, the development environment, and the types of motors it can drive;
2. Based on the types of motors the development board can drive, consider purchasing the appropriate motors;
3. Select the development environment and set it up;
4. Download the motor driver example program provided by JieFa Technology to the motor driver board, connect the motor to the JieFa generator development board according to the circuit diagram and interface instructions for control experiments, and display experimental images and videos;
5. Study and research the motor driver program example provided by JieFa Technology.

Exploring the AC7811 Development Board
https://bbs.21ic.com/icview-3067498-1-1.html
Used a previous model aircraft motor, but unfortunately, it did not drive successfully. I also have a hybrid 42-stepper motor, but due to lack of relevant materials, I only measured the pin wiring relationships using a multimeter.
[Autochips Evaluation] 1. Preparation: Problems Encountered and Solutions
https://bbs.21ic.com/icview-3064064-1-1.html
Preparations mainly include the following content:
1. Software: On Windows 10, installed the relevant software according to the instructions in “Setting Up AC78xx Development Environment Using Eclipse” and “Setting Up AC78xx Development Environment Using VS Code.”
2. Hardware: Prepared one PMSM with/without HALL, one BLDC with/without HALL, ST Link v3 Set, as well as clamps, breadboards, etc.
2. Windows 10 + Eclipse + BLDC + Hall + Encoder

Initial Experience with AC7811 Motor Development Board
https://bbs.21ic.com/icview-3068242-1-1.html
Started with a simple program: opened the GPIO program from the previous SDK, deleted the unnecessary parts; then added references to the core_m3 kernel files and added the corresponding LED and key files.
