I'm using the TI's MSP430-RF2500 board for one of my hobby projects. It uses the built-in CC2500 radio, so the expansion header is in SPI mode (USCIB0). The UART (P3.4, P3.5) is being used for debugging purpose. I'm wondering if there is a way of using I2C on this set up? My understanding is that it's not possible as both USCI of the MSP430F2274 have already been used. So the only option is software I2C. Is my understanding correct?
