现在AD口使用TIM1触发AD转换大部分AD转换不准确
13个转换，只有3个是准确的,通道0、1、2是准确的，其他都不准确



	 



	上升中断采样  U＿ＡＤ   Ｖ＿ＡＤ      初始化ＡＤ１转换 其他通道



	               ↓
下降中断  ＡＤ１采样其他中断，ＡＤ２不采样， ＡＤ１再次指向Ｕ＿ＡＤ



	 



	疑问？



	1、定时器TIM1触发哪些引脚上升中断采样？



	2、定时器TIM1触发哪些引脚下降中断采样？



	3、哪些引脚采样是正确的，哪些是不正确的？

初始化：
void ini_ad1()
{
	NVIC_InitTypeDef  	 NVIC_InitStructure;
	
	RCC->APB2ENR |= 1<<9;	//使能ADC1时钟	 
	RCC->CFGR |=(2<<14);   	//ADC分频因子  4分频
	
	ADC1->CR1 = (0<<16);  //+(1<<5);//设置注入同步，开启注入中断
	ADC1->CR2 = (1<<15)+(0<<20);//ADC1上电，设置左右对齐，设置为TROG事件
	ADC1->SMPR1 = 0;		//采样为1.5个周期
	ADC1->SMPR2 = 0;	//采样为1.5个周期  采样频率为14MHZ
	ADC1->SQR3 =1;
	ADC1->CR2 |= 9;
	while(ADC1->CR2 & 8){}
	ADC1->CR2 |= 5;
	while(ADC1->CR2 & 4){}
}
上升沿中断读取AD值：
		if(!(SIGN_1.STOP_electric_bit))
		{
			while(!(ADC1->SR & 4)){}
			U_adc = ADC1->JDR1 & 0xfff;
			while(!(ADC2->SR & 4)){}
			V_adc = ADC2->JDR1 & 0xfff;
		}
		ADC1->SR = 0;
		ADC2->SR = 0;
上升沿中断换AD通道：
void time1_ad_updata()
{
	unsigned int i=AD_counter;
	if(i & 0xfff)
	{
		ADC1->CR2 &= ~1;
		return;
	}
	switch((i>>12) & 0xf)
	{
		case 0:
			ADC1->SQR3 = 0;
//			ADC1->CR2 |= 1;
			break;
		case 1:
			ADC1->SQR3 = 3;
//			ADC1->CR2 |= 1;
			break;
		case 2:
			ADC1->SQR3 = 4;
//			ADC1->CR2 |= 1;
			break;
		case 3:
			ADC1->SQR3 = 5;
//			ADC1->CR2 |= 1;
			break;
		case 4:
			ADC1->SQR3 = 6;
//			ADC1->CR2 |= 1;
			break;
		case 5:
			ADC1->SQR3 = 7;
//			ADC1->CR2 |= 1;
			break;
		case 6:
			ADC1->SQR3 = 11;
//			ADC1->CR2 |= 1;
			break;
		case 7:
			ADC1->SQR3 = 12;
//			ADC1->CR2 |= 1;
			break;
		case 8:
			ADC1->SQR3 = 14;
//			ADC1->CR2 |= 1;
			break;
		case 9:
			ADC1->SQR3 = 13;
//			ADC1->CR2 |= 1;
			break;
		default:
			ADC1->CR2 &= ~1;
			break;
	}
}
下降沿中断读AD值：
void read_other_ad()
{
	if(!(SIGN_1.STOP_electric_bit))
	{
		switch(ADC1->SQR3 & 0x1F)
		{
			case 0:
				while(!(ADC1->SR & 4)){}
				adc_30v_data = ADC1->JDR1 & 0xfff;
				break;
			case 3:
				while(!(ADC1->SR & 4)){}
				adc_led_i_data = ADC1->JDR1 & 0xfff;
				break;
			case 4:
				while(!(ADC1->SR & 4)){}
				adc_5v_i_data = ADC1->JDR1 & 0xfff;
				break;
			case 5:
				while(!(ADC1->SR & 4)){}
				adc_12v_i_data = ADC1->JDR1 & 0xfff;
				break;
			case 6:
				while(!(ADC1->SR & 4)){}
				adc_30v_i_data = ADC1->JDR1 & 0xfff;
				break;
			case 7:
				while(!(ADC1->SR & 4)){}
				adc_5v_data = ADC1->JDR1 & 0xfff;
				break;
			case 11:
				while(!(ADC1->SR & 4)){}
				adc_bat30v_data = ADC1->JDR1 & 0xfff;
				break;
			case 12:
				while(!(ADC1->SR & 4)){}
				adc_bat_data = ADC1->JDR1 & 0xfff;
				break;
			case 13:
				while(!(ADC1->SR & 4)){}
				adc_hot_data = ADC1->JDR1 & 0xfff;
			case 14:
				while(!(ADC1->SR & 4)){}
				adc_12v_data = ADC1->JDR1 & 0xfff;
				break;
			default:
				break;
		}
	}
	ADC1->SR = 0;
	ADC1->SQR3 =1;
	ADC2->CR2 |= 1;
	ADC1->CR2 |= 1;
}
T1中断（去掉不必要的）：
void TIM1_UP_IRQHandler(void)	
{
	TIM1->SR = 0;
	if(TIM1->CR1 & 0X10)
	{
		if(!(SIGN_1.STOP_electric_bit))
		{
			while(!(ADC1->SR & 4)){}
			U_adc = ADC1->JDR1 & 0xfff;
			while(!(ADC2->SR & 4)){}
			V_adc = ADC2->JDR1 & 0xfff;
		}
		ADC1->SR = 0;
		ADC2->SR = 0;
		ADC2->CR2 &= ~1;
		time1_ad_updata();
	}
	else
	{
		read_other_ad();
	}
