MSP430f5506 - multiple slaves over one SPI interface

Hello!

Right now I have an MSP430f5438a on my CC1120dk and for my own PCB I am using a MSP430f5506 and I want to have two CC1120 transceivers to communicate with over one SPI interface. In the easylink code example the CS_N pin is used as a simple GPIO to communicate with the CC1120. Is it possible for me just to have SIMO, SOMI and CLK connected to both my transceivers and just have the two CS_N signals to the transceivers on different GPIOS? This should make it possible for me to communicate with two different transceivers using the same interface by only using different GPIOs for CS_N signal? 

Best regards!

  • Yes, this is the way to do it. Multiple slaves -> multiple chip select signals.
