Re: 3.12.12版本 PWM会翻转

{
OPERATE_RET rt = OPRT_OK;
UINT32_T frequency = PWM_FREQUENCY;
UINT32_T count = 0;

Code: Select all

/*pwm init*/
TUYA_PWM_BASE_CFG_T pwm_cfg = {
    .duty = PWM_DUTY, /* 1-10000 */
    .frequency = PWM_FREQUENCY,
    .polarity  = TUYA_PWM_NEGATIVE,
};
TUYA_CALL_ERR_GOTO(tkl_pwm_init(PWM_ID, &pwm_cfg), __EXIT);

/*start PWM3*/
TUYA_CALL_ERR_GOTO(tkl_pwm_start(PWM_ID), __EXIT);
TAL_PR_NOTICE("PWM%d start", PWM_ID);

while (1) {
    /*Frequency, duty cycle settings*/
    pwm_cfg.frequency = frequency;
    TUYA_CALL_ERR_LOG(tkl_pwm_info_set(PWM_ID, &pwm_cfg)); //If tkl_pwm_frequency_set is implemented, you can call this function.

    TUYA_CALL_ERR_LOG(tkl_pwm_start(PWM_ID));
    TAL_PR_NOTICE("PWM%d , frequency: %d", PWM_ID,  frequency);

    /*close pwm*/
    if(count >= 3) {
        break;
    }
    count++;
    frequency = frequency+10000;

    tal_system_sleep(2000);
}

TUYA_CALL_ERR_LOG(tkl_pwm_stop(PWM_ID));

__EXIT:
TAL_PR_NOTICE("PWM task is finished, will delete");
tal_thread_delete(sg_pwm_handle);
return;
}

demo少了tkl_io_pin_to_func设置接口，内部能完善一下demo吗

该 demo 需要兼容不同芯片平台，这里代码上不能添加 tkl_io_pin_to_func 操作。但添加了注释提示用户如何获取 pwm id
