Hi,
For understanding the app_timer lib, I created a piece of very simple code with SDK 12.3.0 and S132 present, but got some problem with it.
My intention is to start a single shoot timer, and start it again when it got expired and toggle a LED at the same time, but it's been found that the handler has never been performed.
here is the code:
#include <stdint.h>
#include "nrf_gpio.h"
#include "nrf_gpiote.h"
#include "sdk_config.h"
//#include "nrf_ud_gpiote.h"
#include "SystemConfig.h"
#include "app_timer.h"
#define APP_TIMER_OP_QUEUE_SIZE 4
APP_TIMER_DEF(m_led_timer_id);
void led_timer_handler(void *p_context)
{
app_timer_start(m_led_timer_id, APP_TIMER_TICKS(200, APP_TIMER_PRESCALER), NULL);
nrf_gpio_pin_toggle(LED2_PIN);
}
int main(void)
{
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
ret_code_t err_code = app_timer_create(&m_led_timer_id,
APP_TIMER_MODE_SINGLE_SHOT,
led_timer_handler);
APP_ERROR_CHECK(err_code);
nrf_gpio_cfg_output(LED2_PIN);
//GPIOTE_init();
err_code = app_timer_start(m_led_timer_id, APP_TIMER_TICKS(200, APP_TIMER_PRESCALER), NULL);
APP_ERROR_CHECK(err_code);
while (true) {
}
}
I'm wondering if I've missed anything?
Any comments are appreciated!!!
