ARM, RISC-V контроллеры

я в четверке вот так делаю, у двушки по моему будет также.  #define ADC_DR_ADDRESS ((uint32_t) & (ADC1->DR)) /******************************************************************************* */ void adc1Init(void){ ADC_InitTypeDef ADC_InitStructure = {0}; ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b; ADC_InitStructure.ADC_ScanConvMode = DISABLE; ADC_InitStructure.ADC_ContinuousConvMode = ENABLE; ADC_InitStructure.ADC_ExternalTrigConvEdge = ADC_ExternalTrigConvEdge_None; ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_T1_CC1; ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right; ADC_InitStructure.ADC_NbrOfConversion = 1; ADC_Init(ADC1, &ADC_InitStructure); /* ADC regular channel configuration */ //ADC_RegularChannelConfig(ADC1, ADC_Channel_TempSensor, 2, ADC_SampleTime_480Cycles); //ADC_RegularChannelConfig(ADC1, ADC_Channel_Vrefint, 1, ADC_SampleTime_480Cycles); ADC_RegularChannelConfig(ADC1, ADC_Channel_10, 1, ADC_SampleTime_15Cycles); ADC_Cmd(ADC1, ENABLE); } void Applicaton_tag::init(void){ DMA_InitTypeDef DMA_InitStructure = {0}; /* Enable ADC3, DMA2 and GPIO clocks ****************************************/ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_DMA2, ENABLE); DMA_DoubleBufferModeConfig(DMA2_Stream0, (uint32_t)dmaBuf[1], DMA_Memory_1); DMA_DoubleBufferModeCmd(DMA2_Stream0, ENABLE); /* DMA2 Stream0 channel2 configuration **************************************/ DMA_InitStructure.DMA_Channel = DMA_Channel_0; DMA_InitStructure.DMA_PeripheralBaseAddr = (uint32_t)ADC_DR_ADDRESS; DMA_InitStructure.DMA_Memory0BaseAddr = (uint32_t)dmaBuf[0]; DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralToMemory; DMA_InitStructure.DMA_BufferSize = DMA_BUF_SIZE; DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable; DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable; DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord; DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord; DMA_InitStructure.DMA_Mode = DMA_Mode_Circular; DMA_InitStructure.DMA_Priority = DMA_Priority_High; DMA_InitStructure.DMA_FIFOMode = DMA_FIFOMode_Disable; DMA_InitStructure.DMA_FIFOThreshold = DMA_FIFOThreshold_HalfFull; DMA_InitStructure.DMA_MemoryBurst = DMA_MemoryBurst_Single; DMA_InitStructure.DMA_PeripheralBurst = DMA_PeripheralBurst_Single; DMA_Init(DMA2_Stream0, &DMA_InitStructure); DMA_Cmd(DMA2_Stream0, ENABLE); adcCmnInit(); adc1Init(); adc2Init(); //adc3Init(); /* Enable DMA request after last transfer (Single-ADC mode) */ ADC_DMARequestAfterLastTransferCmd(ADC1, ENABLE); /* Enable ADC3 DMA */ ADC_DMACmd(ADC1, ENABLE); ADC_AnalogWatchdogThresholdsConfig(ADC2, limitVal[SI_I2].max, limitVal[SI_I2].min); /* Configure channel14 as the single analog watchdog guarded channel */ ADC_AnalogWatchdogSingleChannelConfig(ADC2, ADC_Channel_13); /* Enable analog watchdog on one regular channel */ ADC_AnalogWatchdogCmd(ADC2, ADC_AnalogWatchdog_AllRegEnable); //DACconfig(); //TIM_Config(); ADC2->CR1 &= ~(uint32_t)ADC_CR1_AWDIE; ADC1->CR2 |= (uint32_t)ADC_CR2_SWSTART; ADC2->CR2 |= (uint32_t)ADC_CR2_SWSTART; //ADC3->CR2 |= (uint32_t)ADC_CR2_SWSTART; NVIC_InitTypeDef NVIC_InitStructure = {0}; NVIC_InitStructure.NVIC_IRQChannel = DMA2_Stream0_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); DMA_ITConfig(DMA2_Stream0 ,DMA_IT_TC , ENABLE); } /******************************************************************************* */ extern "C" void DMA2_Stream0_IRQHandler(void){ if (DMA_GetITStatus(DMA2_Stream0, DMA_IT_TCIF0) != RESET){ register uint16_t *pt; register uint32_t dataL = 0; #pragma data_alignment=4 //static uint32_t dataSum = 0; static uint32_t cnt = 0; X1_ON(); DMA_ClearITPendingBit(DMA2_Stream0, DMA_IT_TCIF0); if (DMA_GetCurrentMemoryTarget(DMA2_Stream0) != 0){ pt = (uint16_t *) dmaBuf[0]; }else pt = (uint16_t *) dmaBuf[1]; cnt++; for(int i = 0; i < (DMA_BUF_SIZE / 8); i++){ dataL += pt[0]; dataL += pt[1]; dataL += pt[2]; dataL += pt[3]; dataL += pt[4]; dataL += pt[5]; dataL += pt[6]; dataL += pt[7]; pt += 8; } dataL = dataL / DMA_BUF_SIZE; X1_OFF(); } дма работет в режиме двойной буферизации. ну и блюмбатека, не кошерно. Звиняйте.
