Hi,
I am also looking for software that will run under linux or DOS to program the PICAXE, and am prepared to help write it if there is enough help out there. I am a bit surprised this hasn't been done already, given the ease with which normal PICs can be programmed, but realise there are some difficulties in obtaining information about the protocol before work can start. Has anybody found out if the PICAXE internal/programming specs are likely to be released by the suppliers??
