mackrackit,

Those notes are really interesting and informative, I'm working my way through them, cheers.

Next you will want to get a HAM licence

Mmm............

Problem?:

I'm thinking I should have ordered the: "rfPIC software and complete documentation (on CD)"?

There was no CD in either of the boxes. I'm thinking I'm up the creek without it? Or can I get by without the CD?

Sorry I know, more questions.

This might be a place to start

I have not used the rfPIC modules but I think we can figure it out.

A quick look at the data sheet.
Header J3 in the PICKIT1 needs to be used after removing the chip from the evaluation socket. My PICKIT1 just has holes for J3, if yours is that way you will need to bring wire off it to a bread board. Looks like J3 pin#1 is on the edge of the board.

Then after the module is programed it should be able to "stand alone" on the bread board.

Hi mackrackit

Absolutely, I tracked down the Microchip.pdf (same one I think) anyway my PICkit1 does have header J3 on it, so that's a help.

I spent ages last night mulling over how all this might work and it seemed to me that I either:

1/ I need two PICkit1 boards one for the TX and one for the RX.

2/ The TX is 'stand_alone' with a battery fitted - However, the TX has a socket for a 12F675 (you have to break some tracks for this to work I think) So I'm not sure if the TX will work without the 12F675 and tracks broken in some kind of test mode (if that makes sense). Or will only work as 'stand_alone' with a program loaded into the 12F675 and tracks broken.

Both modules are stand alone. The 8 pin socket on the transmitter is optional. I would not cut anything at the moment.

It is my understanding that the rfPIC12F675 is just a 12F675 with RF on board, plugging the modules into the PICKIT1 is just a way to program them.

I bet the software for the PICKIT1 sees the modules as is. Have you plugged either one into the PICKIT1 yet?

One the modules are programed you should be able to power them with out the programmer attached.

Maybe...
