示例程序

#include <LCD5110_Basic.h>
LCD5110 myGLCD(3,4,5,6,7);
extern uint8_t SmallFont[];
extern uint8_t MediumNumbers[];
extern uint8_t BigNumbers[];
void setup()
{
  myGLCD.InitLCD(); //Intializing LCD
}

void loop()
{
    myGLCD.setFont(SmallFont);
    myGLCD.print("Hello World",CENTER,16);
  
    delay(1000);
    myGLCD.clrScr();

}

常用函数

• LCD5110(SCK,MOSI,DC,RST,CS);//设置引脚
  Usage: LCD5110 myGLCD(8,9,10,11,12);
• InitLCD([contrast]);//初始化
  Usage:myGLCD.initLCD();
• setContrast(contrast);//设置对比度（0-127）
  Usage:myGLCD.setContrast(70);
• enableSleep();//设置睡眠状态
  Usage:myGLCD.enableSleep();
• disableSleep();//关闭睡眠状态
  Usage:myGLCD.disableSleep();
• clrScr();//清屏
  Usage:myGLCD.clrScr();
• clrRow(row[,start_x[,end_x]]);//清除行的一部分或者整行
  Usage:myGLCD.clrRow(5，42);
• invert(mode);//倒置
  Usage:myGLCD.invert(true);
• print(st,x,y);//显示字符串
  Usage:myGLCD.print("Hello Wrold", CENTER, 0);
• printNumI(num,x,y[,length[,filler]]);//显示整数
  Usage:myGLCD.printNumI(num, CENTER, 0);
• printNumF(num,dec,x,y[,divider[,length[,filler]]]);//显示小数
  Usage:myGLCD.printNumF(num, 3,CENTER, 0);
• setFont(fontname);//设置字体大小
  Usage:myGLCD.setFont(SmallFont);
• drawBitmap(x,y,data,sx,sy);//用于显示自定义字符
  Usage:myGLCD.drawBitmap(0,0,bitmap,32,32);
