Gentleman,
For those who followed the progress in designing a IR system who can be used to program the Picaxe-chips, the imposible became possible. I reached a distance up to 3.2 meters. To increase this to 5 meter is just a matter of time. Both channels work on 455 kHz and a "ïnterlock" between the Xmitter and receiver is used to avoid 'shouting in your own ear" Futhermore 3 08M are used with embedded software to control the proces, 1 on the receiving site (the uP to be programmed) and 2 on the "editor" site. Various standard 74HCTXX's are used to make the impossible possible. I hope that there is a possibility on this site to publish the drawings and description. In the meanwhile a search is in progress to replace the IR part with a RF link. I think that the "programming process" knowledge is vital when using RF instead of IR. Most of the tricks are always valid regardless the transmission medium.
