Protocol analyzer for IR and RF

Wednesday, December 19th, 2012

We stumbled across this protocol analysis software aptly named Protocol Analyzer. "The Protocol Analyzer is a small tool that can catch, analyze and decode “slow” pulse based protocols. Typical examples are IR-Remotes or RF-Remotes. It uses the microphone input to read the signals. Since this is almost always available with...

Networked infrared remote control receiver

Monday, April 18th, 2011

IgorPlugUDP is an ethernet-enabled infrared receiver. This is an old hack that kmmankad brought up in the forum. What makes it really cool is that the ethernet is bitbanged using nothing but the bare pins of an ATMEGA168. It is transmit-only, it cannot receive network packets, but that's enough for...
