TDA4VM: TDA4VM SPI Communication

Part Number: TDA4VM

Hi team,

In our case we are using SPI communication for sending the data, we are sending data from slave to master, and not sending any data to slave.


As per our understanding, we can make transaction. txbuf (master) to point NULL directly right . Or it causes any problem.


As from reading the note in spi.h we got that we can only keep .txrxmode to TX_ONLY,, no enum for RX_ONLY.

In one of the threads , I have  RX_ONLY but we couldn't find any such enum, if it's possible let us know.

I am attaching the link, Please have a look into it.
