TMS320F28335: SPI Receive only mode - In Master mode

Sujith Kallara

Part Number: TMS320F28335

Hello all,

Can we configure the SPI module to a receive only mode? Not in the SPI slave mode, In master mode itself?. I'm looking for a continuous SPI clock generation.

In order to receive data via SPI in master mode, you need write TX data to the SPI. The SPI will simultaneously transmit and receive data on each SPI clock. If you want continuous SPI clock, you will need continuous TX data.

Thank you.

We tried with McBSP and generated a continuous clock signal without writing data. Thank you for the support.
