I want to make an MSP430G2553 communicate using SPI with a 7-segment display and with another microcontroller MSP430G2452.
So the MSP430G2553 would be the master and both the 7-segment display and MSP430G2452 would be slaves. The master will acquire a measurement from the slave microcontroller MSP430G2452 and then display it on the 7-segment display once per second.
I have been led to believe that it is not possible to connect the two slaves on the same SPI bus. Is this the case and if so why not?
