TuyaOS PWM (tkl_pwm)

Demo: …/examples/driver_pwm/example_driver_pwm.c

Confirm first

• PWM id and pin. Demo notes: if pin→pwm mapping is unclear, use tkl_io_pin_to_func in platform tkl_pinmux (when available).

Pattern

#include "tkl_pwm.h"
#include "tal_log.h"

#define PWM_ID  0

void app_pwm_start(void)
{
    TUYA_PWM_BASE_CFG_T pwm_cfg = {0};
    /* frequency / duty / polarity — copy fields from demo for this SDK */
    if (tkl_pwm_init(PWM_ID, &pwm_cfg) != OPRT_OK) {
        TAL_PR_ERR("pwm init fail");
        return;
    }
    tkl_pwm_start(PWM_ID);

    /* update duty/freq at runtime */
    tkl_pwm_info_set(PWM_ID, &pwm_cfg);
}

void app_pwm_stop(void)
{
    tkl_pwm_stop(PWM_ID);
}
