The table below presents the MISC driver API correspondence between STM32F10x and

STM32F0xx Libraries.

ADC configuration

This section gives an example of how to port existing code from STM32F1 series to

STM32F0 series.

The example below shows how to configure the ADC1 to convert continuously channel 14 in

STM32F1 series:

/* ADCCLK = PCLK2/4 */

RCC_ADCCLKConfig(RCC_PCLK2_Div4);

/* Enable ADC's APB interface clock */

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);

/* Configure ADC1 to convert continously channel14 */

ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;

ADC_InitStructure.ADC_ScanConvMode = ENABLE;

ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;

ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;

ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;

ADC_InitStructure.ADC_NbrOfChannel = 1;

ADC_Init(ADC1, &ADC_InitStructure);

/* ADC1 regular channel14 configuration */

ADC_RegularChannelConfig(ADC1, ADC_Channel_14, 1,

ADC_SampleTime_55Cycles5);

/* Enable ADC1's DMA interface */

ADC_DMACmd(ADC1, ENABLE);

/* Enable ADC1 */
