IRQHandler Interrupt with ESB

[steve4879]

void timer_init(void) 
{
	NRF_TIMER2->TASKS_STOP = 1; // Stop timer
	NRF_TIMER2->MODE = TIMER_MODE_MODE_Timer;
	NRF_TIMER2->BITMODE = (TIMER_BITMODE_BITMODE_24Bit << TIMER_BITMODE_BITMODE_Pos);
	NRF_TIMER2->PRESCALER = 8; // 1us resolution
	NRF_TIMER2->TASKS_CLEAR = 1; // Clear timer
	NRF_TIMER2->CC[0] = 500000; // should be 1 second
	NRF_TIMER2->INTENSET = TIMER_INTENSET_COMPARE0_Enabled << TIMER_INTENSET_COMPARE0_Pos; 
	NRF_TIMER2->SHORTS = (TIMER_SHORTS_COMPARE0_CLEAR_Enabled << TIMER_SHORTS_COMPARE0_CLEAR_Pos);
	NVIC_EnableIRQ(TIMER2_IRQn);
	NRF_TIMER2->TASKS_START = 1; // Start TIMER 
}

void TIMER2_IRQHandler(void)
{
	if(NRF_TIMER2->EVENTS_COMPARE[0] != 0)
    {
        NRF_TIMER2->EVENTS_COMPARE[0] = 0;
		NRF_TIMER2->CC[0] += 500000;
        m_timer_counter++;
    }
}

I am trying to have an interrupt that would allow ESB RF to change so I could essentially scan several channels for broadcasts. However I can not get the above code to work. I have the interval large for now, but I can not even set a breakpoint in the interrupt handler. I started with the ESB RX example and added the above code.

So I found the solution after some time. 

Since i am using the Zephyr environment that runs the RTOS you need to do something like: 

IRQ_DIRECT_CONNECT(TIMER1_IRQn, 0, interrupt_handler, 0);
