After we blogged about his IR helicopter automatic altitude control video, amieres added another video. In this one he explains how to decode the IR protocol using a program he developed and the IR Toy.
His software has many useful options like frame length recognition with a rounding option to eliminate signal travel time. A replace option is implemented to help with decoding different signal pulses as “1”s or “0”s, as well as a output mode in which you could remove the start and stop bits and concentrate on the data packets only.
Once the signal is decoded there is a code generating tab which allows you to send data with the decoded protocol to your IR device. While he made it for use with his Helicopter toy, the options it has could be applied to decode many other devices.
