STM32F103 單片機(jī)的AD采集程序

單片機(jī)源程序如下:

#include "led.h"
#include "delay.h"
#include "key.h"
#include "sys.h"
#include "lcd.h"
#include "usart.h"
#include "adc.h"
int main(void)
{
u16 adcx;
float temp;
delay_init(); //延時函數(shù)初始化
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);//設(shè)置中斷優(yōu)先級分組為組2：2位搶占優(yōu)先級，2位響應(yīng)優(yōu)先級
uart_init(115200); //串口初始化為115200
LED_Init(); //LED端口初始化
LCD_Init();
Adc_Init(); //ADC初始化
POINT_COLOR=RED;//設(shè)置字體為紅色
LCD_ShowString(60,50,200,16,16,"WarShip STM32");
LCD_ShowString(60,70,200,16,16,"ADC TEST");
LCD_ShowString(60,90,200,16,16,"ATOM@ALIENTEK");
LCD_ShowString(60,110,200,16,16,"2015/1/14");
//顯示提示信息
POINT_COLOR=BLUE;//設(shè)置字體為藍(lán)色
LCD_ShowString(60,130,200,16,16,"ADC_CH0_VAL:");
LCD_ShowString(60,150,200,16,16,"ADC_CH0_VOL:0.000V");
while(1)
{
adcx=Get_Adc_Average(ADC_Channel_1,10);
LCD_ShowxNum(156,130,adcx,4,16,0);//顯示ADC的值
temp=(float)adcx*(3.3/4096);
adcx=temp;
LCD_ShowxNum(156,150,adcx,1,16,0);//顯示電壓值
temp-=adcx;
temp*=1000;
LCD_ShowxNum(172,150,temp,3,16,0X80);
LED0=!LED0;
delay_ms(250);
}
}
