[Training Camp] Steering gear gripper

Overview

Use Lichuang express cardboard as structural parts,

The main control uses HI3861,

The module has 1 user button and 2 servos (the servos use IO delay to simulate PWM)

The user button is GPIO2

The left servo is GPIO8 and the right servo is GPIO9

When installing, do not put the cardboard on first, but burn the program first. When the button is not pressed, it is in the clamped state, and when it is pressed, it is in the released state.

Updated the PCB diagram, removed the 5V battery interface and high-current LDO module, which are not necessary, leaving the PCA9685 interface (tested, no problem)

Use ubuntu20 system, VSCODE compiler (provided by training camp)

The programming language is developed in C language. I have tested the internal PWM and found that the frequency is not up to standard. There is no way.

I also tested the timer, and it has a minimum period of 10ms, but nothing worked. I finally chose to use the IO simulation method to control the servo. The program defines three PWM functions of the servo for reference.

PCB physical picture

Clamp made of cardboard (cardboard is very brittle, so it works fine)
