i am working on a rf tranceiver using chipcon cc2500 and at 89c51
i would like to get some tips from you experianced people
can we directly interface the system to the 8051 pins?
people says that we have to configure the cc 2500 before using
how's it possible
will the normal spi interface program will work with the same?

I am using cc2500 with atmega32.
I want to use cc2500 in uart mode because i think in spi mode it is too big to handle.
for that purpose i did following things:
1. i reset cc2500 using sres command strobe.(0x30)
2. then i configured the data rate to 9600 by writing appropriate values of DRATE_E and DRATE_M in respective registers.

you didn't say whether the code should be in c or asm.

run the whole circuit at 3V including the 89S8253. You'll want to use the hardware SPI module in the 89S8253.

i'm first trying to establish SPI communication directly between 2 micros(test code).
now waht i'm nt sure is that

Another way could be the use fo a modern integrated receiver with RSSI capibilities such as TI CC1101 (sub-1 GHz) or cc2500 (2.4 GHz).
The idea is based on the capability of measure the received signal amplitude inside the IC bandwidth (usually you can trim it, so you will have a RBW parameter).
