Compiler/TDA3: How to communicate with external devices using McSPI?

Hi.

I want to exchange data with TDA3xx-EVM board and Raspberry Pi using SPI communication.

To use this feature, I found the mcspiMasterSlave_spi1_spi2.c file and thought that it could do SPI communication.

However, this example is seen as an example of SPI1 (Master) and SPI2 (Slave) communication in the board.

Can I modify this example to test the communication between SPI1 (Master) and Raspberry Pi (Slave) ...?

If this is possible, can you provide a guideline?

Or should I refer to a whole new example ...?

I am sorry for not being able to test and ask more since it is the first implementation of SPI communication.

Thank you.

Hi,

You can refer this example, Use only the SPI1 configuration which is configured as master.

You will also need to connect the SPI pins between the TDA3xx and Raspberry Pi.

Prasad

Sorry, can I ask more questions?

Is it possible to create an echo program using raspberry pie as master and TDA3xx-EVM as slave through this example?

Yes, You can make tda3xx as slave and configure as done in the example.
Use only the SPI2 configuration which is configured as slave.
