Other Parts Discussed in Thread: DAC7760, MSP430I2021

DAC7760 supports SPI communication and MSP430i2021 also have SPI communication.However MSP430i2021 have only 8-bit shift register whereas DAC7760 have 24-bit shift register.Anyone can provide some demo code for communication between this two.

SPI is a bit stream. It makes no difference whether you transmit a 24 bit value or three 8 bit values. just keep an eye on endianess. Start (and end) of the stream are synchronized with the chip select signal.
However, some devices expect a number of bits that is not a multiple of 8. In most of these cases, the device will just take the last n bits sent and ignore any excess bits.
