STM32F103 单片机的AD采集程序
单片机源程序如下:
- #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(); //延时函数初始化
- NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);//设置中断优先级分组为组2：2位抢占优先级，2位响应优先级
- uart_init(115200); //串口初始化为115200
- LED_Init(); //LED端口初始化
- LCD_Init();
- Adc_Init(); //ADC初始化
- POINT_COLOR=RED;//设置字体为红色
- 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");
- //显示提示信息
- POINT_COLOR=BLUE;//设置字体为蓝色
- 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);//显示ADC的值
- temp=(float)adcx*(3.3/4096);
- adcx=temp;
- LCD_ShowxNum(156,150,adcx,1,16,0);//显示电压值
- temp-=adcx;
- temp*=1000;

- LED0=!LED0;
- delay_ms(250);
