NRF51822 Interrupt Service Routine handling

[Krzysiek]

Hello, I was using wiringPiSPI() to connect via SPI and so i was using wiringPiISR function to create an interupt handler that will do callback to the user suplied function. Now I moved to module with NRF architecture. How can I handle interuptions the way i was doing it on the Raspberry PI? I'm using spi_master.h to connect via SPI. Is there any ready to use ISR handle the way it was made on Raspberry?

Krzysiek: It's not covered in the SPI protocol, so you would need to either use the SPI Master to poll or implement an extra GPIO interrupt so that the slave can trigger the interrupt when there is data he wants to send. You can think of using the GPIOTE driver.
