    40X4 LCD HDM40416L-4 Question

    Just today at work they were going to throw away 2 computerized cash register tops. So I yanked the LCD display. On the back it is listed as HDM40416L-4. Will this be compatible with the LCD drivers from http://www.markuszehnder.ch/projects...n/download.php ?

    I got two for free so I figured what the heck, I was going to buy some anyways, but probably 2X40. Only problem they are too long for my dash so I will have to think of something

    Question

    does anyone know if the plugin really works for this model? I got the blocks to come up but when I use the plugin it does nothing. Any ideas? I was wondering if I wired it up wrong.

    Because you may have the data lines wired back to front, and that would prevent it working.

    is there some generic program to test if I hooked it all up right? I just am not sure if the LCD Software Winamp plugins are compatible with my model.
