Hey there all, I wired up and have kind of got working a maplin DEM16217 LCD (2x16) and setup LCDSmartie before hooking it up to the PC. I got a display but it looks like this.

Any ideas why?

Disregard that last note ... I got it working ... The cable I was using to connect the pc to the project was junk.

Now I have a new problem ... After about 5/10 minutes of displaying info the LCD shows nothing yet smartie is running and the only way to get back my display is to restart the machine ... Even if I unplug the LCD from power and PC and then reconnect it still doesn't show a thing.

Then after restarting tha machine it go's through the whole thing again.

Any ideas as to why?

it's very curious, if you unplug and the plug the display back to the power source it should show all dots black on the first line. If this is true then restarting just smartie should solve the problem temporarily.

For a permanent solution try increasing the delay when you set up the driver (it should show something there to help you)

I just restarted smartie this morning after seeing that it wa blank again and it seems to be fine, Fingers crossed.

I'll try some delay.

I increased the refresh to 200 and it seems to be working for longer ... Strange! I have smartie 5.4 and can't find the delay.

The delay is a value you write in the configuration part of the display adapter, it is something like LPT1,____; it is written there, i can't remember exactly what you should write.
