hey Nigel, great work .. this tutorial will surely help me a lot !
I'm a bit busy now, will study it after a few days....
One thing that came to my mind...
Can we use the PICs with integrated transmitters to send packets of data wirelessly..The rfPIC12F675, I think has an integrated ASK Transmitter for the 433MHz range. I have not delved into this at all, but want your opinion on this. Is it feasible, as compared to using exrternal radio modules, in terms of quick code development , cost per IC, quality of transmission.. ?
Since both, the modules and the PIC use 433Mhz, the issues about legal radio bands in my place is no more an issue.
