小弟是新手，参考国外网站

http://milesburton.com/LCD_Smartie_Powered_By_Arduino_Liquid_Crystal_library
但位置不对，和有乱码
希望大大可赐教

你买的是什么型号的？国产的12864可能改过了，特别是带汉字字库的。
也许可以试试这个

我試用了这个库，ST7920串口显示，但只出数字

#include "LCD12864RSPI.h"
#define AR_SIZE( a ) sizeof( a ) / sizeof( a )

LCD12864RSPI LCDA(A0,A1,A2);

///LCD12864RSPI(int _latchPin,int _dataPin,int _clockPin):
//RS->A0,R/W->A1,E->A2

//LCD Smartie matrix.dll 4x16 ;

void setup() {
Serial.begin(9600);
}

byte serial_getch(){

int incoming;
while (Serial.available()==0){}
incoming = Serial.read();
return (byte) (incoming &0xff);
}
void loop(){
byte rxbyte;
byte temp;
int row = 0;
rxbyte = serial_getch();
if (rxbyte == 254) //Matrix Orbital uses 254 prefix for commands
{
switch (serial_getch())
{
case 66: //backlight on (at previously set brightness)
   // not implemented
   break;
case 70: //backlight off
   // not implemented
   break;

case 71://set cursor position
   row = (serial_getch() - 1);//get column byte
   switch (serial_getch())//get row byte
   {
   case 1:
   row = 0;//row1
   break;
   case 2:
   row = 1;//row2
   break;
   case 3:
   row = 2;//row3
   break;
   case 4:
   row = 3;//row4
   break;
   default:
   break;
   }
   LCDA.setCursor(row,0);
   break;
   case 72://cursor home (reset display position)
   break;
case 74://show underline cursor
   break;
case 75://underline cursor off
case 84://block cursor off
   break;
case 76://move cursor left
   break;
case 77://move cursor right
   break;
case 78://define custom char
   break;
case 83://show blinking block cursor
   break;
case 86://GPO OFF
   //implement later
   break;
case 87://GPO ON
   break;
case 88://clear display, cursor home
   LCDA.clear();
   break;
case 152: //set and remember (doesn't save value, though)
case 153: //set backlight brightness
   //not implemented
   break;

   //these commands ignored (no parameters)
case 35: //read serial number
case 36: //read version number
case 55: //read module type
case 59: //exit flow-control mode
case 65: //auto transmit keypresses
case 96: //auto-repeat mode off (keypad)
case 67: //auto line-wrap on
case 68: //auto line-wrap off
case 81: //auto scroll on
case 82: //auto scroll off
case 104: //init horiz bar graph
case 109: //init med size digits
case 115: //init narrow vert bar graph
case 118: //init wide vert bar graph
   break;
default:
   //all other commands ignored and parameter byte discarded
   temp = serial_getch();//dump the command code
   break;
}
return;
}

LCDA.print(rxbyte);//otherwise a plain char so we print it to lcd
return;

}

在LCD 中出现的是全DEC 数字例如串口输出”A” LCD 是６５请问如何解决
谢谢

Serial.print("A");
LCDA.print("A");

Serial.print("A");
LCDA.print("A");

原来最尾是
LCDA.print(char(rxbyte));
谢谢大大回覆

请问可不可以用u8glib做同一結果？可教教小弟吗？
