Hardware interrupt example

[umair]

Hello! I am newbie, I am using nordic nrf51822a board. Can anyone give me hardware interrupt example code and tell me how to enable it?

Hi,

Interrupts are essentially enabled by using two steps:

• Enable the interrupt vector using NVIC_EnableIRQ(IRQ_type)
• Set the appropriate bit in NRF_wantedperipheral->INTENSET = MASK_ENABLE;

I'm attaching a small example on how to setup the ADC w/ISR.

Best regards Håkon
