Hi Triggered by an external interrupt, I would like to send 64 bytes buffer (array) through SPI Bus using DMA, can I have any example for the same Target MCU : MKM34Z128 (50 Mhz) Thank you, Paddy

Hello @phamsa,

Unfortunately, this specific example that you mention is not available but in the SDK for the KM34 (75MHz) you can find an example using an SPI DMA transfer using a software trigger. The SDK is not straight compatible with the KM34 (50 MHz) but the SPI and DMA should be the same.

Best Regards,
Alexis Andalon
