尝试编译一个非常简单的程序来测试 hd44780 lcd 控制器的wiringpi库:
#include <iostream>
#include <wiringPi.h>
#include <lcd.h>
...
int main()
{
init_wiringpi;
fd = lcdInit(2, 16, 4, 11,10 , 0,1,2,3,0,0,0,0) ;
...
return = 0;
}
Build Messages
LCD_first.cpp - undefined reference to `lcdInit'
LCD_first.cpp - undefined reference to `lcdPosition'
LCD_first.cpp - undefined reference to `lcdPuts'
