[Design of FOC control board based on Liangshan School]

【Objectives】:
1. Control motor rotation
2. Position loop
3. Current loop
4. PID
【Circuit Introduction】:
I. Power conversion
12V to 3.3V
chip data
II. Power inducement circuit
to induce 12V power supply
III. Encoder interface
IV. Current detection
V. Motor drive
【What I Learned】:
Making motor drive circuit,
writing basic FOC program,
composition and use of brushless motor
【Problems and Solutions】:
I. Numerous errors when compiling ARM5 with Keil 5
: Solution: This post 【MDK5.37 does not pre-install Compiler Version 5 solution - Zhihu (zhihu.com)】
II. Lack of understanding of FOC basics
: Solution: Study Deng Ge's teaching video 【Write a better library than SimpleFOC (dengfoc.com)】
III. Unclear circuit layout
: Solution: Use LCSC 3D preview + mental imagery
IV. PWM output but insufficient current to rotate
: Solution: Buy a power battery (not yet, borrowing from others is fine)
