自己筆記本系統(tǒng)是kalilinux，自帶anduino開發(fā)環(huán)境，但沒有microduino的板子驅(qū)動。
將winddows下的IDE目錄下的hardware/Microduino/ 目錄拷貝到linux下/usr/share/duino/。
啟動Arduino IDE就能在工具=>板卡 內(nèi)找到Microduino core的4種類型的板了，
Microduino Core （Atmega328P@16M,5V）
Microduino Core （Atmega328P@8M,3.3V）選擇這個
Microduino Core （Atmega168PA@16M,5V）
Microduino Core （Atmega168PA@8M,3.3V）
接上lcd1602，四線接法，做個測試
軟件：
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 ); //設(shè)置地址
while (*s) //寫字符串
{
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線 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個地址起
delay(50);
LCD_Write_String(2,1,str2);//第2行，第2個地址起
delay(5000);
LCD_Command_Write(0x01);//
delay(50);
LCD_Write_String(0,0,str3);
delay(50);
LCD_Write_String(0,1,str4);
delay(5000);
}
顯示正常。
