Has anyone tried using DMA with FlexIO?

[Xlerb]

Using FlexIO as SPI on KL17 and would like to use a DMA controller to feed it.

Ref manual says it's possible. Anyone tried it?

Are there any examples?

Thanks,

Martin.

Hi Martin,
You can build and download the SDK_2.1_MKL17Z256xxx4 from MCUXpresso Config Tools.
There are two examples seems meet your needs.

Best Regards,

Hi Robin,

Thanks that was helpful.

It's a shame that the documentation in the reference manual isn't good enough to write code without needing to spend a lot of time looking at examples.

Anyway, thanks for your help.

Regards,

Martin.
