hi Kekoa, thanks for your answer, About the strange stop bit, I was wrong (John Barnes also mailed me about that, thanks John) it was indeed the parity bit. About the startbit (which is inverted to the data) I'm (almost) absolutly sure, I measured (...) (24 years ago, 6-Nov-01, to lugnet.robotics.rcx)

hi all, has anyone experience with the IR codes transmitted by the remote controler. As far as I know, these codes are normal direct commands, which you also send from your PC, using the standard IR tower. The documentation on this issue is not very (...)

hi all, I'm working on what I call an "InfraRed All module" , which should become IR-tower, IR-sensor, IR-audio-remote, etc. Measuring the IR pulses from the IR-tower I encountered the following effects According to what Kekoa Proudfoot found "A '0' (...)

Thanks for the information. We started with the mathematical approach, but this seems to be extremely complex and not too useful for a reliable design with LEGO-Technic and the RCX.
