Posted on January 17, 2015 at 18:54Hi,
I'm using HAL driver to configure ADC module. This is my code:
void adc_config()
{
AdcHandle.Instance = ADC1;
__ADC1_CLK_ENABLE();
HAL_ADC_DeInit(&AdcHandle);
AdcHandle.Init.ClockPrescaler = ADC_CLOCKPRESCALER_PCLK_DIV2;
AdcHandle.Init.Resolution = ADC_RESOLUTION12b;
AdcHandle.Init.DataAlign = ADC_DATAALIGN_RIGHT;
AdcHandle.Init.ScanConvMode = DISABLE;
AdcHandle.Init.EOCSelection = DISABLE;
AdcHandle.Init.ContinuousConvMode = ENABLE;
AdcHandle.Init.DMAContinuousRequests = DISABLE;
AdcHandle.Init.NbrOfConversion = 1;
AdcHandle.Init.DiscontinuousConvMode = DISABLE;
AdcHandle.Init.NbrOfDiscConversion = 0;
AdcHandle.Init.ExternalTrigConvEdge = ADC_EXTERNALTRIGCONVEDGE_NONE;
AdcHandle.Init.ExternalTrigConv = ADC_EXTERNALTRIGCONV_T1_CC1;
HAL_ADC_Init(&AdcHandle);
ADC_ChannelConfTypeDef sConfig;
sConfig.Channel = ADC_CHANNEL_10; //PC0
sConfig.Rank = 1;
sConfig.SamplingTime = ADC_SAMPLETIME_3CYCLES;
sConfig.Offset = 0;
HAL_ADC_ConfigChannel(&AdcHandle, &sConfig);
}
int adc_convert()
{
HAL_ADC_Start(&AdcHandle);//Start the conversion
HAL_ADC_PollForConversion(&AdcHandle,10);//Processing the conversion
return HAL_ADC_GetValue(&AdcHandle); //Return the converted data
}
When I compile that, i get an error messages ''undefined reference to `HAL_ADC_DeInit'''. The error message is the same for all HAL_ADC functions... I use Eclipse + GCC.
When I manually open stm32f4xx_hal_adc.c file, I can find the definition of the HAL functions.
When I use CTR+Left click on the function in main.c, i get the .h file od hal_adc, but when i again click on the function i don't get the .c file of the hal_adc.
What is the problem?
Thanks
