Hi, can anyone tell me how to configure hardware timers in nrf connect sdk. using nrfx_timer driver? not the kernel timers.
Hi, can anyone tell me how to configure hardware timers in nrf connect sdk. using nrfx_timer driver? not the kernel timers.
I implemented this code in the blinky with the example you mentioned using NRFX API
const nrfx_timer_t timer_led = NRFX_TIMER_INSTANCE(0);
static void wait_timer_handler(nrf_timer_event_t event_type, void *context)
{
printk("timer expired");
}
static int timer_init(void)
{
nrfx_err_t err;
nrfx_timer_config_t timer_cfg = {
.frequency = NRF_TIMER_FREQ_1MHz,
.mode = NRF_TIMER_MODE_TIMER,
.bit_width = NRF_TIMER_BIT_WIDTH_16,
};
err = nrfx_timer_init(&timer_led, &timer_cfg, wait_timer_handler);
if (err != NRFX_SUCCESS) {
printk("nrfx_timer_init failed with: %d\n", err);
return -EAGAIN;
}
IRQ_CONNECT(TIMER1_IRQn, 3,
nrfx_timer_1_irq_handler, NULL, 0);
nrfx_timer_compare(&timer_led,
NRF_TIMER_CC_CHANNEL0,
nrfx_timer_ms_to_ticks(&timer_led, 1000000),
true);
nrfx_timer_enable(&timer_led);
return 0;
}
void main(void)
{
int err;
err = timer_init();
if (err) {
return;
printk("timer init failed\n");
}
printk("timer initialized\n");
for(;;)
{
k_msleep(1000);
}
}
added all the config options too, as in dtm example and flashed it to the nrf52840 dk board. it just keeps resetting like this
