BLK202A-4BR Keypad in Linux
Posted: Sun Jan 19, 2003 5:39 pm
I am trying to create an MP3 Jukebox using Linux and C. I am able to pass information to the LCD, however when I try to read from the keypad, I have no luck. I am trying to use the F1 (N) key to enter a menu. Listed below is the code, please show me where I am going wrong.
Code: Select all
while(a != 'N')
{
clear_display();
cursor_home();
write(fd, " MP3 Jukebox Ready! ", 40);
for(i=1; i<100000000; i++);
write(fd, " MP3 Jukebox Press F1 for Menu ", 40);
for(i=1; i<100000000; i++);
read(fd, &a, 1);
}
