hd44780 display problem

[shebu_18]

Hy i have a problem with an hd44780 compatible lcd, it is 4x20. I made all the connections write, i verified them 4 times. The problem is this: when i connect it to the powersuply it displays the first and the third row(the rectangle 5x7 dots are white), after this i plug the data connectro(paralel) in to the slot and nothing happens. i installed port95nt and lcd smartie is configured write. i made it work one time but after 3 weeks it didn't work(i used the same computer).

Please help, Thanks

You are still using Windows XP or older?

If you changed to Vista or 7 then you must use inpout32 instead of port95nt.

Also, the correct procedure is: connect LCD to computer, power it, start Smartie.

I use WIn 7 x64. I tried it with inpout32.dll but still nothing. I don't have a paralel port on my MB so i bought a pci card that creates an paralel port. i think i have a problem with the adressing of lcdsmartie.

For PCI parallel port cards, you must find the address of the card and put that into the Startup Parameters. Look in Device Manager under Ports, double-click the entry for the parallel/printer port, then look at the Resources tab for the I/O Range. Use the first number as the parameter for Smartie, preceded by a $ sign (eg $9C00).

Thanks for the help! It works now thank you so much! I worked on an Usb to paralel board and now i don't have to make the PCB. I thought it must be something with the I/O, but didn't know what. Thanks again. Nice program!
THanks again.
