Dear friends,
I am trying to run the PWM in my project. I have:
-
added the PWM driver successfully (4.0.0-2.alpha, nrf_drv_pwm.c, nrf_drv_pwm.h) ;
-
set #define PWM0_ENABLED 1 into nrf_drv_config.h
-
enabled PWM into sdk_config.h;
-
PWM initialization routine is like this:
/* --------------------------------------------------------------------*/
static nrf_drv_pwm_t m_pwm0 = NRF_DRV_PWM_INSTANCE(0);
void init_pwm(void) { uint32_t err_code;
nrf_drv_pwm_config_t const config0 =
{
.output_pins =
{
5|NRF_DRV_PWM_PIN_INVERTED, // channel 0
NRF_DRV_PWM_PIN_NOT_USED, // channel 1
NRF_DRV_PWM_PIN_NOT_USED, // channel 2
NRF_DRV_PWM_PIN_NOT_USED, // channel 3
},
.irq_priority = APP_IRQ_PRIORITY_LOW,
.base_clock = NRF_PWM_CLK_125kHz,
.count_mode = NRF_PWM_MODE_UP,
.top_value = 7812,
.load_mode = NRF_PWM_LOAD_INDIVIDUAL,
.step_mode = NRF_PWM_STEP_AUTO
};
// Init PWM without error handler
err_code=nrf_drv_pwm_init(&m_pwm0, &config0, NULL);
}
/--------------------------------------------------------------------------/
- nrf_drv_pwm_init returns NRF_SUCCESS
After all this effort the PWM obviously doesn't start; add/remove NRF_DRV_PWM_PIN_INVERTED has influence over the state of the output pin, but things stop there. I would be grateful for any advice how to solve/investigate the problem.
