How to use SPI interrupt to process external flash read and write in S32K144?

Hi,

    Recently, I began to debug the SPI read and write external flash in S32K144 platform. However, If I don't use interrupt to process read flash, there may lose some information. If I using Interrupt to process read flash, I don't know how to return the current function task to use the read value to continue next opreation.

   So can anyone to share the demo to refer.

Thanks!

Hi,

I assume that you are using the SDK LPSPI driver.

I'm not sure if I understand what is the issue here, but you can install a call back function.

It is shown in the example that is attached here:

How do I know if the SPI slave has received the data? 

Please read the SDK documentation available in the SDK installation folder.
