本设计介绍了一种采用STC系列带A/D转换的单片机STC12C2052AD设计的比例遥控系统。该系统主要包括发射机电路和接收机电路。其中,发射机电路采用多个电位器(可变电阻)分压作为比例控制信号,通过对发射端单片机的软件程序设计将输出的多路经过A/D转换后的数字信号进行编码并由串行口送到发射模块发射;接收机电路的任务则是把接收到的信号进行适当放大并从中解调出编码信号,然后通过对接收端单片机的软件程序设计将该信号转换成相应的电动机驱动控制信号,从而完成对模型的方向和速度的控制。
This design describes a STC series with A / D conversion microcontroller STC12C2052AD designed remote control system. The system mainly includes transmitter circuit and receiver circuit. Among them, the transmitter circuit uses a plurality of potentiometers (variable resistors) as the proportional control voltage divider, through the transmitter software design of the microcontroller will be output after the multiplexed A / D converted digital signal encoded by the string The port sends to the transmitting module to transmit; the task of the receiver circuit is to amplify the received signal and demodulate the encoded signal therefrom, and then convert the signal into the corresponding motor driver through software programming of the receiving end single-chip microcomputer Control signals, thus completing the control of the direction and speed of the model.
