这篇文章介绍了常用5通道（前后左右加速）玩具遥控电路中的RX2c及TX2c信号原理、采用的电路，并用AT89C2051实现与以上两个芯片的兼容控制，如果有想深入研究以上两款芯片的朋友，可以看参考一下-This paper is about RX2c and TX2c,which is used in remote control in toys.The two chips have five control channel(forward,back,left,right,acclerate). This paper also illustrates what the principles of these two chips is, how　using　AT89C2051　to control the toys like the two chips. If you want to study the RX2C and TX2C　s signal, this paper maybe helpful.
