sd card activate using interrupt

[Teja114]

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.

Hi @danielmartynek ,

I want to write LPSPI code with interrupt method for S32k142 device .

currently iam using polling method.

can you please guide us how to write LPSPI driver using interrupt method

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
