【Training Camp】Little Jianzhong

Overview

Realize the basic functions of Xiaojian Clock, draw a circle, and continue to improve it later.

It is developed based on the OpenHarmony open source Hongmeng system. The chip used is hi3861, which supports 16-channel servo control, GPIO, ADC, PWM and other operations.

Common operations such as writing and drawing graphics have been implemented

Chip solution: multi-channel steering gear control board based on HiSilicon Hi3861 chip and PCA9685

Product core parameters:
Working voltage: 7.4V~20V with overheating and overcurrent protection

This exercise is an understanding of Hongmeng. If you need to continue to have a deeper understanding of this system, you will definitely gain more. Thanks for this opportunity, I also feel the sense of accomplishment of completing a project. I hope to have more opportunities to participate in the future.

The BOM table really cannot be uploaded, so I just put the attachment directly.
