Adafruit PWM Servo Driver Library

二自由度云台实现人脸追踪。 首先是使用一款名字叫做IP摄像头的APP 采集手机摄像头的图像，在手机上建立一个视频流服务器。在局域网下，PC通过IP还有端口号获取图像。使用OpenCV的人脸检测的API获取人脸在画面中的位置，根据人脸位置距离画面中心的x轴与y轴的偏移量(offset) ，通过P比例控制(PID控制中最简单的一种)控制二自由度云台上臂与下臂的旋转角度，将角度信息通过串口通信UART发送给ESP32单片机(不限于ESP32，STM32,Arduino都可以)解析执行对应的操作，从而使得人脸尽可能处在画面的正中间。

This software is a devLib extension to wiringPi http://wiringpi.com/ and enables it to control the Adafruit PCA9685 16-Channel 12-bit PWM/Servo Driver http://www.adafruit.com/products/815 via I2C interface.

Wrote this extension for some BBC micro:bit accessories developed by my former company. Due to TCEA's management issue, two of my coworkers and me decided to leave in summer 2019. This repo is archived for now.
