I've got a 16x2 character LCD wired up on a breadboard, and I've switched back and forth between the Maxim design and the Hobby-Boards design, but I can't get anything to display on the LCD. I can see the DS2408 in owfs, and when I power up the LCD I see all all dark boxes on the top row, which I think is what it should look like before it's initialized. Then if I try to "echo hello > message" under LCD_H or LCD_M (depending on which way I have it wired at the time) the LCD goes blank. I've tried playing with the contrast and I can see the spaces getting darker but there are no characters displayed. I've checked and double checked my wiring, and switched back and forth between the two designs several times, swapped out 3 different DS2408s and three different LCDs, but I just can't get anything to display.
Is there a trick to getting it to work? Something I might have overlooked? I'd really appreciate any help or advice anyone could give.
Thanks,
Ben Griffith
