how to occur interrupt on SPIM with easyDMA END event?

[Haruki Kawakami]

Hi

I want to get external acceleration sensor values with SPIM using easyDMA on the sensor interruption (using GPIOTE). then after getting all data, I want to calculate them using algorithm on CPU.

In other words, getting the sensor data without CPU and calculate the data using CPU on the SPI easyDMA END event.

please tell me how to implement this.

Thank you.

Have you looked at the SPI Master Example? The SPI master driver support EasyDMA and uses the END event to trigger a software interrupt (seen as a driver event from the application).

Thank you for your answer. Is the event_handler called only on the END event? In other words, ENDRX, ENDTX, or STOPPED doesn't call the event_handler?

The event handler is only called on the END event.
