AVR Freaks

Hi,

I have created a simple project with  https://start.atmel.com/ for the SAMC21E18A (I have only init the PWM). Sadly, no matter what parameter I set with "pwm_set_parameters", the duty cycle stay at 99%.

Did I miss something for the initialization ?

struct pwm_descriptor PWM_0;

void PWM_1_PORT_init(void)
{

    gpio_set_pin_function(PA22, PINMUX_PA22E_TC0_WO0);
}

void PWM_1_CLOCK_init(void)
{
    hri_mclk_set_APBCMASK_TC0_bit(MCLK);
    hri_gclk_write_PCHCTRL_reg(GCLK, TC0_GCLK_ID, CONF_GCLK_TC0_SRC | (1 << GCLK_PCHCTRL_CHEN_Pos));
}

void PWM_1_init(void)
{
    PWM_1_CLOCK_init();
    PWM_1_PORT_init();
    pwm_init(&PWM_1, TC0, _tc_get_pwm());

}

int main(void)
{
    /* Initializes MCU, drivers and middleware */
    atmel_start_init();

    pwm_set_parameters(&PWM_1, 10000, 5000);
    
    pwm_enable(&PWM_1);

    /* Replace with your application code */
    while (1) {
    }
}
