A 6 Channel PPM PIC code for 12F629 and 12F675，There are four examples here and they are work well for RC receiver.

51单片机萝丽二代八通PPM接收机源码，爽接WMC飞控飞四轴-51 single LORI II eight-PPM receiver source, then cool WMC axis flight control fly

用51单片机模拟红外发送和接收解码的过程，软件实现红外发送，接收端实现红外数据解码，并用数码管显示出来，主要是对红外PWM(脉冲宽度调制) 和PPM(脉冲位置调制) 两种形式编码的研究-Simulation of infrared transmission with 51 single-chip microcomputer and the decoding process, software realization of infrared transmission, infrared recei
