【Training Camp】Hi3861 servo driver

Overview

# Simulate the little bell and complete a handwritten signature machine. ##There are several errors in the current project: 1. The USR button is connected to a pull-up and cannot be used. It can be changed to a pull-down. 2. LED0 is equivalent to pulling up GPIO2, which cannot be used. It can be changed to high level. 3. The purchased PCA9685 module has pins installed on the top surface and can only be inserted vertically. ## Unverified parts: 1. The battery-powered part has not been verified. 2. The ultrasonic module program has not been written and has not been verified. 3. OLED has not been verified. ## Unfortunately due to lack of time, all codes are original examples and need to be further developed! ## Thanks for the occasional successful download, but I got stuck in the download section and never read the hardware manual. Thanks to Chuanzhi Xiao Qi for the tip!
