/*     SN_PWM_TIM3_OUT_init模块的使用方法：

方法一：初始定时器3的pwm输出：
     int main(void){
		 
       SN_SYSCLK_set(SYSCLK_48MHZ);
			 std_delay_init();
       SN_PWM_TIM3_OUT_init(TIM3_CH1_PA0|TIM3_CH2_PA4 ，1000); //设置定时器3通道1 和 通道2 输出占空比数是1000的方波，输出io分别是PA0 ,PA4
			 
			 while(1){
			     std_delayms(500);
			     SN_PWM_TIMx_CH_Duty(TIM3,TIM_CHANNEL_1,3000); //调整通道1 输出的占空比大小
			 }

   }
	 
	 
方法二：初始定时器1的pwm输出：
     int main(void){
		 
       SN_SYSCLK_set(SYSCLK_48MHZ);
			 std_delay_init();
       SN_PWM_TIM1_OUT_init(TIM1_CH1_PA0|TIM1_CH2_PA1 	 ，1000); //设置定时器3通道1 和 通道2 输出占空比数是1000的方波，输出io分别是PA0 ,PA4
			 
			 while(1){
			     std_delayms(500);
			     SN_PWM_TIMx_CH_Duty(TIM1,TIM_CHANNEL_1,3000); //调整通道1 输出的占空比大小
			 }

   }	 
	 

方法三： 初始定时器1 的互补PWM输出
//注意：相关死区时间和空闲电平要在SN_PWM.h 文件中设定

main.c文件：
uint16_t EN = 0 ;  //仿真中修改该变量，控制PWM输出或关闭
uint32_t DUT = 1;
int main(void){
		 
       SN_SYSCLK_set(SYSCLK_48MHZ);
			 std_delay_init();
			 SN_PWM_TIM1_OUT_Complementary(TIM1_CH2N_PA0); //设置互补通道，注意要先设定互补通道后，才能初始化pwm输出
       SN_PWM_TIM1_OUT_init(TIM1_CH2_PA1,1000);     //设置定时器3通道1 和 通道2 输出占空比数是1000的方波，输出io分别是PA0 ,PA4

			 while(1){
			     std_delayms(500);
			     
				   if(EN){
						       SN_PWM_TIMx_CH_Duty(TIM1,TIM_CHANNEL_2,100*(DUT++)); //调整通道2 输出的占空比大小
					         SN_TIM_PWM_Start(TIM1,TIM_CHANNEL_2); 
					 }else{
					         SN_TIM_PWM_Stop(TIM1,TIM_CHANNEL_2);				 
					 }
				 
				 
				 
			 }
