STM32F4 Discovery dual adc timer triggered

Good evening everyone, I'm trying to sample two signals through TIM2 using ADC in dual regular simultaneous mode with a trigger from TIM2. When configuring the ADC in dual mode, it only reads and performs a single conversion on one channel. Does anyone have any idea what I might be doing wrong?

 

//Start of Multimode HAL_ADC_Start(&hadc2); if(HAL_ADCEx_MultiModeStart_DMA(&hadc1 , (uint32_t *)dmaBuffer, 100) != HAL_OK){ Error_Handler(); } if(HAL_TIM_Base_Start(&htim2) != HAL_OK){ Error_Handler(); } // Timer 2 Config static void MX_TIM2_Init(void) { /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_OC_InitTypeDef sConfigOC = {0}; /* USER CODE BEGIN TIM2_Init 1 */ /* USER CODE END TIM2_Init 1 */ htim2.Instance = TIM2; htim2.Init.Prescaler = 0; htim2.Init.CounterMode = TIM_COUNTERMODE_UP; htim2.Init.Period = 1; htim2.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; htim2.Init.AutoReloadPreload = TIM_AUTORELOAD_PRELOAD_DISABLE; if (HAL_TIM_Base_Init(&htim2) != HAL_OK) { Error_Handler(); } sClockSourceConfig.ClockSource = TIM_CLOCKSOURCE_INTERNAL; if (HAL_TIM_ConfigClockSource(&htim2, &sClockSourceConfig) != HAL_OK) { Error_Handler(); } if (HAL_TIM_OC_Init(&htim2) != HAL_OK) { Error_Handler(); } sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE; sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_ENABLE; if (HAL_TIMEx_MasterConfigSynchronization(&htim2, &sMasterConfig) != HAL_OK) { Error_Handler(); } sConfigOC.OCMode = TIM_OCMODE_TIMING; sConfigOC.Pulse = 0; sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH; sConfigOC.OCFastMode = TIM_OCFAST_DISABLE; if (HAL_TIM_OC_ConfigChannel(&htim2, &sConfigOC, TIM_CHANNEL_1) != HAL_OK) { Error_Handler(); } /* USER CODE BEGIN TIM2_Init 2 */ /* USER CODE END TIM2_Init 2 */ } // ADC1 hadc1.Instance = ADC1; hadc1.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc1.Init.Resolution = ADC_RESOLUTION_12B; hadc1.Init.ScanConvMode = DISABLE; hadc1.Init.ContinuousConvMode = DISABLE; hadc1.Init.DiscontinuousConvMode = DISABLE; hadc1.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_RISING; hadc1.Init.ExternalTrigConv = ADC_EXTERNALTRIGCONV_T2_TRGO; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.NbrOfConversion = 1; hadc1.Init.DMAContinuousRequests = DISABLE; hadc1.Init.EOCSelection = ADC_EOC_SINGLE_CONV; //ADC2 hadc2.Instance = ADC2; hadc2.Init.ClockPrescaler = ADC_CLOCK_SYNC_PCLK_DIV2; hadc2.Init.Resolution = ADC_RESOLUTION_12B; hadc2.Init.ScanConvMode = DISABLE; hadc2.Init.ContinuousConvMode = DISABLE; hadc2.Init.DiscontinuousConvMode = DISABLE; hadc2.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc2.Init.NbrOfConversion = 1; hadc2.Init.DMAContinuousRequests = DISABLE; hadc2.Init.EOCSelection = ADC_EOC_SINGLE_CONV;

Period of 1 seems a bit wishful

Don't think it needs master/slave mode enable

Suspect you need to configure multi-mode

Did this successfully on the F4, but was using the SPL

The thing I don't understand is why it only reads one channel and then with the period at 1 it works fine.

Perhaps show the full code. Why do you think it only performs one of the conversions?

Because i'm printing the signals that i'm acquiring
