i am very new to stm32 and i am trying to use ADC module in my stm32f103c6 board, here is the code i've been working on:
#include "main.h"ADC_HandleTypeDef hadc1;DMA_HandleTypeDef hdma_adc1;uint32_t adcBuffer[2];uint32_t adcData[2];void SystemClock_Config(void);static void MX_GPIO_Init(void);static void MX_DMA_Init(void);static void MX_ADC1_Init(void);int main(void){ HAL_Init(); SystemClock_Config(); MX_GPIO_Init(); MX_DMA_Init(); MX_ADC1_Init(); HAL_ADC_Start_DMA(&hadc1, (uint32_t*)adcBuffer, 2); while (1) { HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_5); HAL_Delay(1000); }}void SystemClock_Config(void){ RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; RCC_PeriphCLKInitTypeDef PeriphClkInit = {0}; /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDef structure. */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI; RCC_OscInitStruct.HSIState = RCC_HSI_ON; RCC_OscInitStruct.HSICalibrationValue = RCC_HSICALIBRATION_DEFAULT; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSI_DIV2; RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL2; if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK) { Error_Handler(); } /** Initializes the CPU, AHB and APB buses clocks */ RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK |RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2; RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK; RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1; RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV1; RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV1; if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_0) != HAL_OK) { Error_Handler(); } PeriphClkInit.PeriphClockSelection = RCC_PERIPHCLK_ADC; PeriphClkInit.AdcClockSelection = RCC_ADCPCLK2_DIV2; if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK) { Error_Handler(); }}/** * @brief ADC1 Initialization Function * @param None * @retval None */static void MX_ADC1_Init(void){ /* USER CODE BEGIN ADC1_Init 0 */ /* USER CODE END ADC1_Init 0 */ ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Init 1 */ /* USER CODE END ADC1_Init 1 */ /** Common config */ hadc1.Instance = ADC1; hadc1.Init.ScanConvMode = ADC_SCAN_ENABLE; hadc1.Init.ContinuousConvMode = ENABLE; hadc1.Init.DiscontinuousConvMode = DISABLE; hadc1.Init.ExternalTrigConv = ADC_SOFTWARE_START; hadc1.Init.DataAlign = ADC_DATAALIGN_RIGHT; hadc1.Init.NbrOfConversion = 2; if (HAL_ADC_Init(&hadc1) != HAL_OK) { Error_Handler(); } /** Configure Regular Channel */ sConfig.Channel = ADC_CHANNEL_8; sConfig.Rank = ADC_REGULAR_RANK_1; sConfig.SamplingTime = ADC_SAMPLETIME_1CYCLE_5; if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK) { Error_Handler(); } /** Configure Regular Channel */ sConfig.Channel = ADC_CHANNEL_9; sConfig.Rank = ADC_REGULAR_RANK_2; if (HAL_ADC_ConfigChannel(&hadc1, &sConfig) != HAL_OK) { Error_Handler(); } /* USER CODE BEGIN ADC1_Init 2 */ /* USER CODE END ADC1_Init 2 */}/** * Enable DMA controller clock */static void MX_DMA_Init(void){ /* DMA controller clock enable */ __HAL_RCC_DMA1_CLK_ENABLE(); /* DMA interrupt init */ /* DMA1_Channel1_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA1_Channel1_IRQn, 0, 0); HAL_NVIC_EnableIRQ(DMA1_Channel1_IRQn);}/** * @brief GPIO Initialization Function * @param None * @retval None */static void MX_GPIO_Init(void){ GPIO_InitTypeDef GPIO_InitStruct = {0};/* USER CODE BEGIN MX_GPIO_Init_1 *//* USER CODE END MX_GPIO_Init_1 */ /* GPIO Ports Clock Enable */ __HAL_RCC_GPIOA_CLK_ENABLE(); __HAL_RCC_GPIOB_CLK_ENABLE(); /*Configure GPIO pin Output Level */ HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7|GPIO_PIN_8 |GPIO_PIN_9|GPIO_PIN_10|GPIO_PIN_11, GPIO_PIN_RESET); /*Configure GPIO pins : PA5 PA6 PA7 PA8 PA9 PA10 PA11 */ GPIO_InitStruct.Pin = GPIO_PIN_5|GPIO_PIN_6|GPIO_PIN_7|GPIO_PIN_8 |GPIO_PIN_9|GPIO_PIN_10|GPIO_PIN_11; GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);/* USER CODE BEGIN MX_GPIO_Init_2 *//* USER CODE END MX_GPIO_Init_2 */}/* USER CODE BEGIN 4 *//* USER CODE END 4 *//** * @brief This function is executed in case of error occurrence. * @retval None */void Error_Handler(void){ /* USER CODE BEGIN Error_Handler_Debug */ /* User can add his own implementation to report the HAL error return state */ __disable_irq(); while (1) { } /* USER CODE END Error_Handler_Debug */}#ifdef USE_FULL_ASSERT/** * @brief Reports the name of the source file and the source line number * where the assert_param error has occurred. * @param file: pointer to the source file name * @param line: assert_param error line source number * @retval None */void assert_failed(uint8_t *file, uint32_t line){ /* USER CODE BEGIN 6 */ /* User can add his own implementation to report the file name and line number, ex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */ /* USER CODE END 6 */}#endif /* USE_FULL_ASSERT */My problem is that the LED on pin 5 toggles when i remove the line:
HAL_ADC_Start_DMA(&hadc1, (uint32_t*)adcBuffer, 2);But when i add the line i see no change in the led connected to that pin? I can provide more information if there is more you need to know in my ide, thanks everyone in advance.
