In STM32F0 series, you have to update this code as follows:

...

/* ADCCLK = PCLK/2 */

RCC_ADCCLKConfig(RCC_ADCCLK_PCLK_Div2);

/* Enable ADC1 clock */

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

/* ADC1 configuration */

ADC_InitStructure.ADC_Resolution = ADC_Resolution_12b;

ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;

ADC_InitStructure.ADC_ExternalTrigConvEdge =

ADC_ExternalTrigConvEdge_None;

ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_T1_TRGO;;

ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;

ADC_InitStructure.ADC_ScanDirection = ADC_ScanDirection_Backward;

ADC_Init(ADC1, &ADC_InitStructure);

/* Convert the ADC1 Channel 1 with 55.5 Cycles as sampling time */

ADC_ChannelConfig(ADC1, ADC_Channel_11 , ADC_SampleTime_55_5Cycles);

/* ADC Calibration */

ADC_GetCalibrationFactor(ADC1);

/* ADC DMA request in circular mode */

ADC_DMARequestModeConfig(ADC1, ADC_DMAMode_Circular);

/* Enable ADC_DMA */

ADC_DMACmd(ADC1, ENABLE);
