MSP430FR5969: SPI communication 8, 16, 32 bit

Zampieri Claudio

Part Number: MSP430FR5969

We found the examples for SPI communication using only 8 bits. It works. We wonder if it is possible to implement a SPI communication using 16 or 32 bits.

We used eusci_b_SPI_ex1_slave.c

Hi Claudio,

The SPI module for the MSP430FR5969 is limited to 8 bits of data at a time. If you need 16 or 32 bits of data, send the maximum 8 bits multiple times.

Regards,

Luke
