SDK 2.0 SPI without RX

[ETCTim]

I want to use the SPI driver to transmit data. However, I do not wish to receive data.

Using the SDK 2.0 driver, am I required to create a RX buffer that is the same size as my TX buffer? How do I tell it otherwise?

Thanks,

Tim

Hello Tim,

Yes, it can only send not receive .

Please try define the receive buffer to NULL .

Hope it helps

Have a great day,
Alice
