一、ADC概念

      实现模拟信号转换成数字信号就是这样子= =  

二、代码框架

#include "stm32f10x.h" void delay(u32 kk) { while(kk--); } int main() { u16 ad=0,adc0=0; GPIO_InitTypeDef GPIO_InitStructure; ADC_InitTypeDef ADC_InitStructure; RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA|RCC_APB2Periph_ADC1, ENABLE); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN; GPIO_Init(GPIOA, &GPIO_InitStructure); ADC_InitStructure.ADC_Mode= ADC_Mode_Independent; ADC_InitStructure.ADC_ScanConvMode=DISABLE; 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); ADC_RegularChannelConfig(ADC1,ADC_Channel_0, 1,ADC_SampleTime_1Cycles5); ADC_Cmd(ADC1,ENABLE); ADC_SoftwareStartConvCmd(ADC1,ENABLE); while(1) { while(ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC)==RESET); ad=ADC_GetConversionValue(ADC1); adc0=ad; } }
