单片机设计_智能蓝牙电子秤(51单片机、HX711AD)

想要更多项目私wo!!!

一、电路设计

       智能蓝牙电子称由51单片机、HX711AD称重模块、HC-05蓝牙模块、LCD1602等电路组成硬件部分,然后上传至APP。

二、运行结果

三、部分代码

#include "main.h"
#include "HX711.h"
#include "uart.h"
#include "LCD1602.h"
#include <intrins.h>
#define uchar unsigned char  //ÎÞ·ûºÅ×Ö·ûÐÍ ºê¶¨Òå	±äÁ¿·¶Î§0~255
#define uint  unsigned int	 //ÎÞ·ûºÅÕûÐÍ ºê¶¨Òå	±äÁ¿·¶Î§0~65535

unsigned long HX711_Buffer = 0;
unsigned long Weight_Maopi = 0;
long Weight_Shiwu = 0;

unsigned char flag = 0;
bit Flag_ERROR = 0;
sbit beep= P1^7;

#define GapValue 405

            Send_ASCII(Weight_Shiwu);
