Nice work again Robby, I'm also waiting for this sw, because I couldn't manage to get data from the hw, what could be wrong ..

@ Almera: Are you running Roadrunner when you launch the Configurator?

You have to - just launching the configurator without running RR frontend will not "detect" any id's from any wheel-sensors.

As soon as you foolow Robby's install-tips in the RR plugin forum, and then launch RR, and then the configurator, you can press the "learn" button for any sensor, and it will blink a few times, and then stop blinking.

After a short while, you may see some flashing red alarms in RR on the TPM screen, indicating - press and temps, albeit incorrectly, meaning that the sensors is communicating to the PIC, and the PIC to the plugin s/ware on your frontend.

Erm, I have the 3rd Eye kit, and I made one working setup based on Robby's PIC, but I am just interested to know if yours use the Maxim IC or the TDA chip - my bet is your's is very similar to the ERX-06 you linked to....

I would like to develope a smc solution, which includes RF Receiver, Robby's PIC (but SMC) all onto one pcb, which would make it easier, cheaper, and much smaller.

Just luv tinkering, that's all

edit: There is a very nice Max1473 evaluation kit available, which I can very easily adjus to suit our needs, and provided Robby can provide TSOP 18F2550's, it would be very easy to do an industrial-grade, robust design

I am awaiting pricing on the eval kit, will keep everyone posted.

Thanks, actually I have succeed in the learning process, but still can't see any data in RR. Checked plugin configuration also, seems ok. Maybe something wrong with my hardware, thanks for help, cheers

Ok guys, the new software is availabel for the download here.
