I'm having a great deal of difficulty getting the Timeline Densitron 40x4 character LCD to work. I've been using BoominVolvo's schematic but having little luck in getting the display to do anything but power up the backlight. On the LCD pcb, pin 1 is labeled on the opposite side that the red wire on the ribbon cable is connected to, so which is really pin 1? I have tried wiring the LCD both ways but neither seem to work. It is possible I may have hooked it up the wrong way the first time and fried the controller though, I suppose. I have pin3 connected to the ground instead of the wiper on the 10k contrast potentiometer just to ensure I would have full contrast, and similarly, I have no potentiometer connected to the backlight so that I would have full brightness. Any help is appreciated.
No announcement yet.
