SPI protocal use on MCU & device.
I want know if it can use on two mcu’s communication.
like s3c2440 & msp430.
if it’s ok ,what I should take care.(they have different clock 25MHz & >100MHz)
if it can’t use,tell some reason
thanks
Yes, provided at least one of the MCUs can act as an SPI slave, there should be no problem with that.
The SPI bus should be independently clocked from the CPU clock frequency, so you shouldn’t have a problem finding a common supported speed.
