linux下microduino的驱动

ID:83710 · 发表于 2015-6-25 02:18

   自己笔记本系统是kalilinux，自带anduino开发环境，但没有microduino的板子驱动。
   将winddows下的IDE目录下的hardware/Microduino/  目录拷贝到linux下/usr/share/duino/。
      启动Arduino IDE就能在工具=>板卡内找到Microduino core的4种类型的板了，

Microduino Core （Atmega328P@16M,5V）
Microduino Core （Atmega328P@8M,3.3V）选择这个
Microduino Core （Atmega168PA@16M,5V）
Microduino Core （Atmega168PA@8M,3.3V）

接上lcd1602，四线接法，做个测试

软件：
int LCD1602_RS=12;
int LCD1602_RW=11;
int LCD1602_EN=10;
int DB[] = { 6, 7, 8, 9};
char str1[]="amserver.";
char str2[]="";
char str3[]="This is the";
char str4[]="4-bit interface";

void LCD_Command_Write(int command)
{
int i,temp;
digitalWrite( LCD1602_RS,LOW);
digitalWrite( LCD1602_RW,LOW);
digitalWrite( LCD1602_EN,LOW);

temp=command & 0xf0;
for (i=DB[0]; i <= 9; i++)
{
   digitalWrite(i,temp & 0x80);
   temp <<= 1;
}

digitalWrite( LCD1602_EN,HIGH);
delayMicroseconds(1);
digitalWrite( LCD1602_EN,LOW);

temp=(command & 0x0f)<<4;
for (i=DB[0]; i <= 9; i++)
{
   digitalWrite(i,temp & 0x80);
   temp <<= 1;
}

digitalWrite( LCD1602_EN,HIGH);
delayMicroseconds(1);
digitalWrite( LCD1602_EN,LOW);
}

void LCD_Data_Write(int dat)
{
int i=0,temp;
digitalWrite( LCD1602_RS,HIGH);
digitalWrite( LCD1602_RW,LOW);
digitalWrite( LCD1602_EN,LOW);

temp=dat & 0xf0;
for (i=DB[0]; i <= 9; i++)
{
   digitalWrite(i,temp & 0x80);
   temp <<= 1;
}

digitalWrite( LCD1602_EN,HIGH);
delayMicroseconds(1);
digitalWrite( LCD1602_EN,LOW);

temp=(dat & 0x0f)<<4;
for (i=DB[0]; i <= 9; i++)
{
   digitalWrite(i,temp & 0x80);
   temp <<= 1;
}

digitalWrite( LCD1602_EN,HIGH);
delayMicroseconds(1);
digitalWrite( LCD1602_EN,LOW);
}

void LCD_SET_XY( int x, int y )
{
   int address;
   if (y ==0) address = 0x80 + x;
   else       address = 0xC0 + x;
   LCD_Command_Write(address);
}

void LCD_Write_Char( int x,int y,int dat)
{
   LCD_SET_XY( x, y );
   LCD_Data_Write(dat);
}

void LCD_Write_String(int X,int Y,char *s)
{
      LCD_SET_XY( X, Y ); //设置地址
      while (*s)          //写字符串
      {
      LCD_Data_Write(*s);
      s ++;
      }
}

void setup (void)
{
   int i = 0;
   for (i=6; i <= 12; i++)
   {
      pinMode(i,OUTPUT);
   }
   delay(100);
   LCD_Command_Write(0x28);//4线 2行 5x7
   delay(50);
   LCD_Command_Write(0x06);
   delay(50);
   LCD_Command_Write(0x0c);
   delay(50);
   LCD_Command_Write(0x80);
   delay(50);
   LCD_Command_Write(0x01);
   delay(50);

}

void loop (void)
{
   LCD_Command_Write(0x01);
   delay(50);
   LCD_Write_String(3,0,str1);//第1行，第4个地址起
   delay(50);
   LCD_Write_String(2,1,str2);//第2行，第2个地址起
   delay(5000);
   LCD_Command_Write(0x01);//
   delay(50);
   LCD_Write_String(0,0,str3);
   delay(50);
   LCD_Write_String(0,1,str4);
   delay(5000);

}

显示正常。
