Need help scroll display long file name on LCD Hi everyone, I've used 3D printer over 2 years. It's control software is Marlin firmware and Arduino mega2560 + RAMPS 1.4 ( Additionaly external stepper motor drivers). Also It' has graphic LCD from RepRapDiscount Full Graphic Smart Controller. I would like anyone to solve long file name display on LCD. Regradlee of CLCD or GLCD, it only display 19 charecters of file name. So if I make a print file with over 20 charcters, I can't recognize it. ( In picture below, in 3rd and 4th row ) [attachment 39384 DSC_2409_small.jpg] This problem is very inconvenent me and many users ,maybe. However, Sailfish firmware for Makerbot already support this long file name display using scrollong file name. [attachment 39386 SDCardFeature.JPG] Anyone who alreay solve and use long file name display gives the information Or how can I solve or implement this scrolling long file name.

With the full graphic LCD you have to redraw the entire page, you can't just update one line. This would cause an annoying flicker which is unavoidable because of a low refresh rate. U8Glib uses a frame buffer and needs to write an entire page at a time.]]> thetazzbot Developers Tue, 16 Jun 2015 01:50:10 -0400 https://reprap.org/forum/read.php?2,401779,504084#msg-504084 Re: Need help scroll display long file name on LCD https://reprap.org/forum/read.php?2,401779,504084#msg-504084


This means that some filenames get truncated. But when you select a file, it pops up a window so that you get to see more of the filename:



I think this is a reasonable compromise, but maybe I will make the number of columns configurable in future.

Thank you for your comment. When you solve this problem, please share your idea.
Thank you.]]> jhlee98y Developers Tue, 16 Sep 2014 18:33:21 -0400 https://reprap.org/forum/read.php?2,401779,408265#msg-408265 Re: Need help scroll display long file name on LCD https://reprap.org/forum/read.php?2,401779,408265#msg-408265
Thank you for your comment.

Yes. as like your mention, this problem is only display problem in long file name.
(Not FAT problem in SD file system, Marlin alreay solved FAT problem in large sized SD file system.)

However, I couldn't implement long file name scolling on LCD display source in Marlin firmware.

So. I just need help the implementation of long line text scrolling over LCD width.

Thank you.]]> jhlee98y Developers Tue, 16 Sep 2014 18:29:26 -0400 https://reprap.org/forum/read.php?2,401779,408047#msg-408047 Re: Need help scroll display long file name on LCD https://reprap.org/forum/read.php?2,401779,408047#msg-408047

So its its not just a simple display issue, its more fundamental than that.

But in saying that, it is really over due!I]]> Dust Developers Mon, 01 Sep 2014 05:35:24 -0400 https://reprap.org/forum/read.php?2,401779,401779#msg-401779 Need help scroll display long file name on LCD https://reprap.org/forum/read.php?2,401779,401779#msg-401779
