RF Transceiver modules help

[davewanna]

I have read up about that Ruf-bot project amongst other things.. However where the modules I have are different to others I have read about, is that they are a transceiver. Can transmit and receive with the one module. They also had the TWS/RWS modules, however I wanted 2-way data, so for the price of 2 transmit, and 2 receive modules, I could get just 2 transceivers and save my pennies.

If I ditch this idea, and go for 2 transmitter, and 2 receivers, can one of each be connected to each 16f877 in order to give me bi-direction data? If so how does that work? both connected to the same serial pin, and either module 'selected' as it is needed?

I've hit a wall with the datasheet, it's got many many pages of registers that it looks like I need to set before I even think about sending data.

Regards,

Dave

OOPS,I was looking at the wrong part. Have not used them, but looks like data is shifted into them like a shift register and data out is by serial?

If you use a separate transmitter and receiver you would use two pins on the PIC, one for TX and one for RX. (you could use one pin if serial is software) When sending or receiving you will need to turn the opposite module off.
