Overview

This project mainly uses HiSilicon's hi3861 and pca9685 chips.

hi3861 controls the pca9685 chip through the I2C protocol to generate PWM waveforms to control the rotation of the servo. The pca9658 chip generates up to 16 PWM waves.

The main control board adds pull-up resistors for GPIO13 and GPIO14. When you need to use the second I2C protocol, you can use a jumper cap to connect the pull-up resistors to complete the pull-up of SDA and SCL.

hi3861 also has many functions. See the table below for details:

Why is it that the program I wrote on 430F149 and the hardware are completely fine, but there are problems when ported to 430F169? Is it because the initialization and use of the SPI connected to the
