【1】（添加/删减）定时器

static u32 my_led_timer1 = 0;//初始化
u16 usr_timer_add(void *priv, void (*func)(void *priv), u32 msec, u8 priority);//声明

void my_led_on(void){//需要定时运行的函数
    gpio_direction_output(My_LED_GPIO1, 1);//输出1
}

my_led_timer1 = usr_timer_add(NULL, my_led_on, flashtime, 0);//添加

usr_timer_del(my_led_timer1);//删减

【2】ADC电压检测

//**************app_power_manage.c**************//
u32 my_adc_get_voltage(u32 ch);
void adc_init();
void adc_test();
int adc_init_flag = 0;
static u32 my_GetADC_voltage_timer = 0;

my_GetADC_voltage_timer = usr_timer_add(NULL, adc_test, 1*000, 0);
//**************adc_api.c**************//
adc_add_sample_ch(AD_CH_PA3);
adc_set_sample_freq(AD_CH_PA3, VBAT_SAMPLE_FREQ);
adc_sample(AD_CH_PA3);

void adc_test()
{
     printf("Func:%s() VBAT:value->%d voltage->%d mv\n", __func__,adc_get_value(AD_CH_VBAT), adc_get_voltage(AD_CH_VBAT) * 4);
     printf("Func:%s() PA3:value->%d voltage->%d mv\n", __func__,adc_get_value(AD_CH_PA3), adc_get_voltage(AD_CH_PA3));

}
//**************adc_api.h**************//
//AD channel define
#define AD_CH_PA3    (0x1)

【3】利用定时器实现gpio高低电平交替

//gpio电平输出	1：高电平	0：低电平
#define PB4 IO_PORTA_04
gpio_direction_output(PB4, 1);
//定时器定义
static u32 my_led_timer1 = 0;
static u32 my_led_timer2 = 0;
//函数声明
u16 usr_timer_add(void *priv, void (*func)(void *priv), u32 msec, u8 priority);
//下面是LED事件的设置
//开灯（即高电平输出）
void my_led_on(void){//100ms
   gpio_direction_output(PB4, 1);
}
//关灯（即低电平输出）
void my_led_off(void){
    gpio_direction_output(PB4, 0);
 }
//利用定时器结合开关灯
void my_led_lowflash(void){//慢闪
    int flashtime = 250;//时间可自定义
    usr_timer_del(my_led_timer1);
    usr_timer_del(my_led_timer2);
    my_led_timer1 = usr_timer_add(NULL, my_led_on, flashtime, 0);
    my_led_timer2 = usr_timer_add(NULL, my_led_off, flashtime*2, 0);
}
void my_led_fastflash(void){//快闪
    int flashtime = 100;
    usr_timer_del(my_led_timer1);
    usr_timer_del(my_led_timer2);
    my_led_timer1 = usr_timer_add(NULL, my_led_on, flashtime, 0);
    my_led_timer2 = usr_timer_add(NULL, my_led_off, flashtime*2, 0);
}
void my_led_LongOn(void){
	//删除定时器
    usr_timer_del(my_led_timer1);
    usr_timer_del(my_led_timer2);
    //重新开灯
    my_led_off();
    my_led_on();
}
