connecting MSP430FG4270 to CC2500

Other Parts Discussed in Thread: MSP430FG4270, CC2500, MSP430F2274

Hi,

I am trying connect MSP430FG4270 to CC2500. I baught ez430-Rf2500. On it the MSP430F2274 doesnt have a DAC thats why I went and got MSP430FG4270. Now I need to know how to connect it to CC2500. Any document that shows their connection will help. A schematic like the one in the ez430-Rf2500 will help too.

Thanks

Fahad

    Although the MSP430FG4270 does have a DAC, it lacks a Serial interface module such as a USCI, which the eZ430-RF2500 used to connect the MSP430F2274 and CC2500.  In this scenario, the MSP430F2274 is the master of the SPI interface, so conceivably you could emulate a SPI interface by bit-banging GPIO. 

    There are other MSP430s that have both a DAC and USCI, but they are in much larger packages.
