Hi,

I m using the MSP430F5438 device and I need to use the SPI communication between
the MSP430F5438 ( the master) and the MSP430F2370 (slave). The SPI clock is
sourced by the SMCLK = 1MHz.

The problem is that I obtain a signal in the SMCLK pin but there is no signal
in the SPI clock pin and SPI transmission could'nt start.
Can anyone help me please.

The problem is in the software you've written. Does that help?
Without actually seeing the code, my guess is that you failed to clear UCSWRST, but that's just a shot in the dark.
