tuya 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_funcin platformtkl_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);
}
