No, that's not it. I am referring to this file. It's in the SDK. At least in 1.1.2 and 1.20. It seems to come from the application example, they didn't remove the references to the examples.
Code: Select all
#ifndef __PWM_H__
#define __PWM_H__
/*pwm.h: function and macro definition of PWM API , driver level */
/*user_light.h: user interface for light API, user level*/
/*user_light_adj: API for color changing and lighting effects, user level*/
/*NOTE!! : DO NOT CHANGE THIS FILE*/
/*SUPPORT UP TO 8 PWM CHANNEL*/
#define PWM_CHANNEL_NUM_MAX 8
struct pwm_param {
uint32 period;
uint32 freq;
uint32 duty[PWM_CHANNEL_NUM_MAX]; //PWM_CHANNEL<=8
};
/* pwm_init should be called only once, for now */
void pwm_init(uint32 period, uint32 *duty,uint32 pwm_channel_num,uint32 (*pin_info_list)[3]);
void pwm_start(void);
void pwm_set_duty(uint32 duty, uint8 channel);
uint32 pwm_get_duty(uint8 channel);
void pwm_set_period(uint32 period);
uint32 pwm_get_period(void);
uint32 get_pwm_version(void);
void set_pwm_debug_en(uint8 print_en);
