Hi there,

I'am using SPI protocol for SD card communication , now i have to implement protocol using interrupt mean when slave detect then only spi should works because iam using bare metal programming , when sd card absent that should not have to stop the remaining tasks.

Thanks in advance ..

Hi,

I'm afraid this is too application-dependent.

And the description is not very clear.

BR, Daniel

Hi,

Please refer to the SDK LPSPI driver.

You can start with the lpspi_transfer_s32k142 SDK example that you can find in the S32 Design Studio.

Daniel
