Expiriences with rfPIC12F675?

[KOEZE]

Has anybody here expirimented with the new rfPIC's like the rf12F675 and what are your findings. I'd like to use them in a telemetry application in which the pic part should determine if the condictions are right to transmit data. I'm building a datalogger for use in my model submarine and the frequency of most telemetry transmitters (433mhz) means that penetration in water is at best a few cm. By connecting a watersensor to one of the ports I can detect that the sub is above water, esteblish a connection with the base station and put the datalogger in transmit mode.

I'm especially interested in range, antenna design and general application.

Oh and yes, these are available for samples including matching reciever units.

sounds like fun, I'm working on similar stuff too, and would like to know more as well...

I can't help, but man does that sound like a neat project. Hopefully someone experienced in RF with PICs will chime in.

Microchip rocks. 8)

Its way easyer to get serial radio transmiter/reciver modules.Since you simply give it power and just drive in the seiral data.

rfPICs need a lot of componets around it to get its radio feture to work.

And yea microchip is realy nice wen it comes to samples.I think you can order 4 difrent ICs and max. 5 of each.You can place 2 orders a month.So you can get a total of 40 componets a month from them! (And please dont order too much since tey might find out and close the servise for your country.)

its nice to use those modules for smaller projects and I really appreciate them, but sometimes one needs more control, so I would love it if this thread erupted...
btw thanks to those people who gave me the links to linx, very nice...
