Text displaying issue

[zvpdev]

Thanks for the work done and the provided schema and source code.

I try to connect the display 1x16. When I run the test program (in OS X) I get the result in the console:

MacBookPro:testapp zvp$ ./lcd2usb
-- LCD2USB test application --
-- (c) 2006 by Till Harbaum --

Found LCD2USB device on bus 020 device 022.
Echo test successful!
Firmware version 1.9
Installed controllers: CTRL0
Keys: 0:off 1:off

But only the first 8 positions on the left are used on the display, the remaining 8 are just empty. If I start LCD Smartie in Windows, everything works, but the situation is similar - only the first 8 characters. What could be the problem?

That's not a problem with the lcd2usb itself. Lcd2usb just forwards commands from the pc. And this part works just fine. Otherwise you wouldn't get any output.

So your display is either broken or differs otherwise from the standard.

Try set it up as a 4x20 display instead of 1x16. Then fill it completely with text and check if the other 8 characters come to life. Perhaps your display just arranges the characters differently in memory.

If I set the mode to 2x16 (4x20) for 1x16, the first line is displayed in the first 8 characters, the second line in the second 8 symbols of the display.

Tested work with displays 2x16 and 4x20 - all successfully.

So your 1*16 display is slightly 'odd'. But this sounds like you can easily work around this.

I guess, we can close here? :-)
