Hello everybody, I d like to share some of my routines which are based upon Neutone s ideas. We use this code in our welding machines successfully for more than 2 years now. The protocol is built like this: Firstly the MASTER scans the bu

PPM编码 PPM的编解码方式一般是使用积分电路来实现的，而PCM编解码则是用模/数（A/D）和数/模（D/A）转技术实现的。 -PPM encoding PPM codec integral circuit, the PCM codec with analog/digital (A/D) and digital/analog (D/A) transfer technology.
