有关Arduino lcd1602显示实时数据的问题
我想使用HX711采集压力数据,并且实时显示在lcd1602显示屏上,但是实验的结果是显示屏毫无反应。。。麻烦各位大神看下我的程序,是不是程序出错了啊
const int led=9;
const int button=13;
bool currentbutton=LOW;
bool lastbutton=LOW;
bool buttonstate=false;
#include<LiquidCrystal.h>
#include <HX711.h>
LiquidCrystal lcd(12,11,5,4,3,2);
HX711 hx(7, 8, 128, -0.00011890216);
void setup()
{
pinMode(led,OUTPUT);
pinMode(button,INPUT);
lcd.begin(16,2);
Serial.begin(9600);
}
bool xiaodou(bool last)
{
bool current=digitalRead(button);
if(current!=last)
{
delay(5);
current=digitalRead(button);
}
return current;
}
void loop()
{
currentbutton=xiaodou(lastbutton);
if(lastbutton==LOW&¤tbutton==HIGH)
{
buttonstate=!buttonstate;
}
lastbutton = currentbutton;
digitalWrite(led,buttonstate);
double sum1 = 0;
if(digitalRead(led) == HIGH)
{
for (int i = 0; i < 10; i++)
{
sum1 += hx.bias_read();
}
Serial.print("Force:");
Serial.print(sum1/10);
Serial.println("Kg");
if(Serial.available())
{
delay(1000);
lcd.clear();
while(Serial.available()>0)
{
lcd.write(Serial.read());
}
}
}
}

没有这样的实物,测试不了的。。。。。。不是有串口吗,连接串口去逐行 调试调试
