STM32新手ADC改編輸出十六個(gè)通道數(shù)據(jù)程序源碼

ID:387303 · 發(fā)表于 2018-8-23 11:14

剛開始學(xué) 調(diào)程序可以參考下

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 i=0;
u16 times=0;
u16 adcx;
float temp;
//float temp;
delay_init(); //延時(shí)函數(shù)初始化
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //設(shè)置NVIC中斷分組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
KEY_Init(); //初始化與按鍵連接的硬件接口
Adc_Init();
