Các bước khởi tạo ADC

1.  Enable the ADC interface clock using

RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADCx, ENABLE);
2.  ADC pins configuration
3.  Configure the ADC Prescaler, conversion resolution and data alignment using  the ADC_Init() function.

4.  Activate the ADC peripheral using ADC_Cmd() function.
