Question about customized task for GPIOTE

[Jinyue Zhu]

Hi,

I was writing a program that uses the PPI with event from the timer and the task to one of the GPIO pins. The ideal scenario is that, whenever the timer fires, it will trigger the task and cause the GPIO pin to do a customized behavior (for example, turn on, then turn off, and turn on again).

I was aware that there are some default behavior (tasks) that can be used, such as GPIO_CONFIG_OUT_TASK_TOGGLE. I wonder if there is a way to define a task myself, so that I can update that pin many times in a customized way for each triggering event.

Thanks,

Jinyue

Another completely unrelated question. I am wondering if I can disable the timer in its own event_compare interrupt. The code would look like this:

void timer_event_handler(nrf_timer_event_t event_type, void* p_context) {

    switch (event_type) {
        case NRF_TIMER_EVENT_COMPARE0:

            nrfx_timer_disable(&TIMER);

    }

}

Thanks!

I want to figure out a way to disable the timer after it has run some certain number of times...
