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)

thanks Kekoa, not only for this answer, but also for your great job in disassembling and documenting the the opcodes, I used them a lot in the past. (...) Well I think, I know all about it now, there a few strange things about it: 1. you don't have (...) (24 years ago, 6-Nov-01, to lugnet.robotics.rcx)

(...) As far as I remember (it's been > 10 years) startbits are 0, stopbits are 1. (...) This is strange, are you sure it is not the odd parity bit? (...) That's fine, 1 is the 'passive' and 0 is the 'active' level. Jürgen (24 years ago, 6-Nov-01, to lugnet.robotics.rcx)

(...) What exactly do you want to know about this opcode? I have the full documentation in the form of the firmware disassembly... and it is online. See address 9700 of the disassembly at: (URL) you can't find it, search for "d2 opcode handler". I (...) (24 years ago, 6-Nov-01, to lugnet.robotics.rcx)

(...) I forget exactly how I measured this. I think maybe I hooked a scope directly to the LEDs then sent a constant stream of something to the tower and looked at the waveform on the scope. I don't remember noticing anything funny with the start (...) (24 years ago, 6-Nov-01, to lugnet.robotics.rcx)

| | IR remote control codes.
|

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 (...)

| | IR transmission, strange coding ?

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' (...)

(...) David, thanks for putting this contest on. I admit that I was intrigued when it was announced but did not have time to put an entry together. The idea of a code-only competition on a standard hardware platform is brilliant and opens up the (...)
