STM32F030 Nucleo board da , AN0 analog giriş olarak seçip bu girişe bağlı pot dan gelen gerilimi ölçmek istiyorum.
Ama sürekli 0 okuyorum.
STM32cubemx in üretiği kodlar bunlar.

Bir yerde aşağıdakine benzer fonksiyon olması lazım. Ben kod üretirken ayrı ayrı üretilsin dediğimden adc.c dosyası içinde oluyor:

void HAL_ADC_MspInit(ADC_HandleTypeDef* hadc)
{

  GPIO_InitTypeDef GPIO_InitStruct;
  if(hadc->Instance==ADC1)
  {
  /* USER CODE BEGIN ADC1_MspInit 0 */

  /* USER CODE END ADC1_MspInit 0 */
    /* Peripheral clock enable */
    __ADC1_CLK_ENABLE();
  
    /**ADC GPIO Configuration    
    PA4     ------> ADC_IN4
    PA5     ------> ADC_IN5 
    */
    GPIO_InitStruct.Pin = GPIO_PIN_4|GPIO_PIN_5;
    GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

    /* Peripheral DMA init*/
  
    hdma_adc.Instance = DMA1_Channel1;
    hdma_adc.Init.Direction = DMA_PERIPH_TO_MEMORY;
    hdma_adc.Init.PeriphInc = DMA_PINC_DISABLE;
    hdma_adc.Init.MemInc = DMA_MINC_ENABLE;
    hdma_adc.Init.PeriphDataAlignment = DMA_PDATAALIGN_WORD;
    hdma_adc.Init.MemDataAlignment = DMA_MDATAALIGN_WORD;
    hdma_adc.Init.Mode = DMA_CIRCULAR;
    hdma_adc.Init.Priority = DMA_PRIORITY_MEDIUM;
    HAL_DMA_Init(&hdma_adc);

    __HAL_LINKDMA(hadc,DMA_Handle,hdma_adc);

  /* USER CODE BEGIN ADC1_MspInit 1 */

  /* USER CODE END ADC1_MspInit 1 */
  }
}

stm32f0xx_hal.c icerisinde var.

void HAL_ADC_MspInit(ADC_HandleTypeDef* hadc)
{

  GPIO_InitTypeDef GPIO_InitStruct;
  if(hadc->Instance==ADC1)
  {
  /* USER CODE BEGIN ADC1_MspInit 0 */

  /* USER CODE END ADC1_MspInit 0 */
    /* Peripheral clock enable */
    __ADC1_CLK_ENABLE();
  
    /**ADC GPIO Configuration    
    PA0     ------> ADC_IN0 
    */
    GPIO_InitStruct.Pin = GPIO_PIN_0;
    GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  /* USER CODE BEGIN ADC1_MspInit 1 */

  /* USER CODE END ADC1_MspInit 1 */
  }

}

Hocam donanımda bir hata olma ihtimali var mı? POT bozuk olabilir mi ya da? Gözden kaçabiliyor bazen.

sadogan · 06 Şubat 2016, 13:18:25

Benimde aklıma geldi.
Mbed ile denedim sorunsuz çalıştı.

Cemre. · 06 Şubat 2016, 13:36:56

Hocam MspInit kodunuzda hata var sanırım. IN0'dan okumak istiyorum demişsiniz ancak onu değil de IN4 ve 5'i Analog tanımlamışsınız. CubeMX böyle bir hata yapmadı bende, stm32F4Disco için.

sadogan · 06 Şubat 2016, 13:41:18

JKramer paylaştığı koda öyle,benim paylaştığım kod da AN0 da

JKramer · 06 Şubat 2016, 13:41:42

Yok, o benim koyduğum kod. Bu arada debug'dan (watch) bakıyorsunuz değil mi?

Ek: Sizin kodda HAL_ADC_Start() yok sanırım.

Alıntı Yap(++) ADC conversion by polling:
(+++) Activate the ADC peripheral and start conversions
using function HAL_ADC_Start()
(+++) Wait for ADC conversion completion
using function HAL_ADC_PollForConversion()
(+++) Retrieve conversion results
using function HAL_ADC_GetValue()
(+++) Stop conversion and disable the ADC peripheral
using function HAL_ADC_Stop()

sadogan · 06 Şubat 2016, 13:53:37

HAL_ADC_Start(&hadc);
	HAL_ADC_PollForConversion(&hadc,10);	
	
	adc_val=HAL_ADC_GetValue(&hadc);
	HAL_ADC_Stop(&hadc);

Değişen bir şey yok. hala 0 okuyorum.
Biryerde hatam var ama bulamadım.

Cemre. · 06 Şubat 2016, 14:06:22

Evet hocam haklısınız yanlış görmüşüm.

JKramer · 06 Şubat 2016, 14:09:25

HAL_ADC_Start ve HAL_ADC_PollForConversion fonksiyonları HAL_StatusTypeDef döndürüyor, bunları kontrol edebilirsiniz. 10 ms timeout az geliyordur belki.

hal kütüphanesinde DMA kullanmadan birden fazla kanalı nasıl okuyabiliriz.
örn: ADC1 üzerinde pin 3 ve pin 4 üzerindeki 2 adet potun değerini okuyacağız ?
