应用STC12C5608AD芯片，此芯片自带AD转换，和以前所学的ADC0809有所不同，需要选择I/O的功能，以及特殊功能寄存器的应用

芯片共需要对五个模拟量进行AD转换，不同的变量要存储不同的位置，每次只变化其中一个量，所以调用数据要进行判断选择，只有数值变化才发送数据。

当安卓系统向摇杆发送数据请求，通过数据通讯协议，单片机接收数据，并判断是数据校验出错或请求采样焊接速度和摆枪频率。

当A/D转换完成后，比较数据是否发生变化，若有变化则按照通讯协议发送数据。每次只会有一个数据变化，所以要确定选择位。

数据发送到安卓系统延时1S进行A/D转换，利用定时器，安卓系统也通过中断方式接收数据。所以要确定中断优先级，优先接收安卓请求数据信号。-Applications STC12C5608AD chip, this chip comes with an AD converter, and previously learned ADC0809 different, you need to　I/O functions, and special function registers applications

It requires a total of five chip analog AD conversion, different variables to be stored in different positions, each of which only a change in volume, so the caller data is determined to be selected, only the change in value to the transmission data.

When Andrews system sends a data request to the rocker, through the data communication protocol, MCU receives the data and determines a data validation error or request sampling frequency welding speed and gun pendulum.

When the A/D conversion is completed, more data is changed, if the change of the transmission data in accordance with the protocol. Every time there is only a change of data, so make sure to　bits.

Andrews system sends data to the delay 1S performs A/D conversion, using a timer, Android also by interrupt receiving data. Just be sure to int
