資源簡介
STM32F4 的16通道ADC采集例程,注釋清晰，
/****************************************************************************
PCLK2 = HCLK / 2
下面選擇的是2分頻
ADCCLK = PCLK2 /8 = HCLK / 8 = 168 / 8 = 21M
ADC采樣頻率： Sampling Time + Conversion Time = 480 + 12 cycles = 492cyc
Conversion Time = 21MHz / 492cyc = 42.6ksps.
*****************************************************************************/
/* ADC Common 配置 ----------------------------------------------------------*/
ADC_CommonInitStructure.ADC_Mode = ADC_Mode_Independent;
ADC_CommonInitStructure.ADC_Prescaler = ADC_Prescaler_Div2;
ADC_CommonInitStructure.ADC_DMAAccessMode = ADC_DMAAccessMode_Disabled;
ADC_CommonInitStructure.ADC_TwoSamplingDelay = ADC_TwoSamplingDelay_5Cycles;
ADC_CommonInit(&ADC;_CommonInitStructure);
