使用DMA通道1将ADC1DMA中断中的采样值传输到变量tempV

以下是一个示例代码，用于将ADC1DMA中断中的采样值传输到变量tempV：\n\nc\n// 声明变量tempV\nuint16_t tempV;\n\n// 初始化ADC1和DMA通道1\nvoid ADC1_DMA_Init(void)\n{\n // 启用ADC1时钟\n RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);\n \n // 初始化GPIO引脚\n // ...\n \n // 配置ADC1\n ADC_InitTypeDef ADC_InitStructure;\n ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;\n ADC_InitStructure.ADC_ScanConvMode = DISABLE;\n ADC_InitStructure.ADC_ContinuousConvMode = DISABLE;\n ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;\n ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;\n ADC_InitStructure.ADC_NbrOfChannel = 1;\n ADC_Init(ADC1, &ADC_InitStructure);\n \n // 配置ADC1规则序列\n ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_55Cycles5);\n \n // 启用ADC1 DMA模式\n ADC_DMACmd(ADC1, ENABLE);\n \n // 配置DMA通道1\n RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);\n \n DMA_InitTypeDef DMA_InitStructure;\n DMA_DeInit(DMA1_Channel1);\n DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)&ADC1->DR;\n DMA_InitStructure.DMA_MemoryBaseAddr = (uint32_t)&tempV;\n DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralSRC;\n DMA_InitStructure.DMA_BufferSize = 1;\n DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;\n DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Disable;\n DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;\n DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;\n DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;\n DMA_InitStructure.DMA_Priority = DMA_Priority_High;\n DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;\n DMA_Init(DMA1_Channel1, &DMA_InitStructure);\n \n // 启用DMA通道1\n DMA_Cmd(DMA1_Channel1, ENABLE);\n \n // 启用ADC1\n ADC_Cmd(ADC1, ENABLE);\n \n // 启动ADC1校准\n ADC_ResetCalibration(ADC1);\n while(ADC_GetResetCalibrationStatus(ADC1));\n ADC_StartCalibration(ADC1);\n while(ADC_GetCalibrationStatus(ADC1));\n \n // 启动ADC1转换\n ADC_SoftwareStartConvCmd(ADC1, ENABLE);\n}\n\n// ADC1DMA中断处理函数\nvoid DMA1_Channel1_IRQHandler(void)\n{\n if(DMA_GetFlagStatus(DMA1_FLAG_TC1))\n {\n // 清除DMA1通道1传输完成标志位\n DMA_ClearFlag(DMA1_FLAG_TC1);\n \n // 处理ADC值\n // ...\n }\n}\n\n\n此代码初始化了ADC1和DMA通道1，配置了ADC1的规则序列，并启用了DMA传输。在ADC1DMA中断处理函数中，可以通过处理ADC值来完成后续操作。在本例中，将ADC值传输到变量tempV中。请根据实际需求进行修改。
