从事无线遥控玩具开发工作多年，开发了很多种类的无线遥控玩具产品。总结了很多工作经验。用的绝大部分IC是TX2C（遥控）和RX2C（接收），其功能分别是：前进，后退，左转，右转。笔者利用工作的空闲时间用AT89C2051单片机编出了跟TX2C和RX2C一样的编解码程序，并成功进行了实际制作。编解码与TX2C和RX2C兼容。现将制作原理图和源程序公开给读者参考学习与制作，相信对初学者有极大的帮助，这也是笔者的心愿！其原理图如下：图2为接收部分，图3为发射部分。源程序和仿真文件见附件.-Engaged in the development of wireless remote control toys for many years, the development of many types of wireless remote control toy products. Summed up a lot of work experience. The vast majority of IC is TX2C (remote) and RX2C (reception), its features are: forward, backward, turn left, turn right. I use the work of free time to compile the AT89C2051 microcontroller as with TX2C and RX2C codec program, and successfully carried out the actual production. Codec compatible with TX2C and RX2C. Now produced the schematic and source code is open to the reader is referred to the learning and production, I believe there is a great help for beginners, this is also the wish of the author! The diagram is as follows: Figure 2 to receive part of Figure 3 for the transmitter. Source and simulation files in the annex.
