I have a custom board SDK 15.2 API 6.1
I have a simple PWM going but it seems to just turn the low and set it high when i turn it on. It does not however seem to pulse according to my scope. Nor does it stop. This is in a ble application that has softdevices enabled and LFCLK source. I am tyring to use app_pwm.h instead of the nrf_drv_pwm. I am curious why a simple application doe snot seem to operate though.
static nrf_drv_pwm_t m_pwm0 = NRF_DRV_PWM_INSTANCE(0);
nrf_pwm_values_individual_t seq_values[] = {DUTY_CYCLE, 0, 0, 0};
nrf_pwm_sequence_t const seq =
{
.values.p_individual = seq_values,
.length = NRF_PWM_VALUES_LENGTH(seq_values),
.repeats = 0,
.end_delay = 0
};
void pwm_start(void)
{
nrf_drv_pwm_simple_playback(&m_pwm0, &seq, 1, NRF_DRV_PWM_FLAG_LOOP);
}
void pwm_stop(void)
{
nrf_drv_pwm_stop(&m_pwm0, false);
}
static void pwm_init(void)
{
nrf_drv_pwm_config_t const config0 =
{
.output_pins =
{
OUTPUT_PIN, // 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_LOWEST,
.base_clock = NRF_PWM_CLK_1MHz,
.count_mode = NRF_PWM_MODE_UP,
.top_value = 100,
.load_mode = NRF_PWM_LOAD_INDIVIDUAL,
.step_mode = NRF_PWM_STEP_AUTO
};
// Init PWM without error handler
APP_ERROR_CHECK(nrf_drv_pwm_init(&m_pwm0, &config0, NULL));
}
void int main(void){
pwm_init();
pwm_start();
nrf_delay_ms(2000);
pwm_stop();
}
