摘要
设计的系统是基于STC15W408AS单片机和NF-04-MI-2.4G无线模块设计的遥控小车,主要由遥控发射板和接收驱动板两部分组成。遥控发射板不断将摇杆A/D采样信号和按键信号等信息,通过2.4G无线模块发送至驱动板。接收驱动板根据避障传感器信号和接收到的数据,结合PWM控制技术,完成小车前进、后退、左转弯、右转弯以及转速调节等各种状态控制,利用上位机软件将不同通讯地址码下载到小车,解决了小车相互控制的问题。
This system is a remote control car designed on the basis of STC15W408AS microcontroller and NF-04-MI-2.4G wireless module. It is mainly composed of remote control launch board and receiving driving board. The remote control launch board continuously sends the information of the A/D sampling signal and key signal of the rocker to the driving board through the 2.4G wireless module. Receiving driving board according to the signal of obstacle avoidance sensor and the received data, combined with PWM control technology, completing the car forward, backward, turn left, turn right, speed regulation and all kinds of state control. Using the upper computer software to download the different communication address code into the car, solving the problem of the control of each car.
