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 )


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.


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.

Thanks in advance.

As I understand it Marlin doesn’t know anything about vfat but I do see some VFAT structure details in the code.

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

But in saying that, it is really over due!I

this is a good idea. i always do the labeling after the print. but i guess this is doable. ill try this one too

The vfat stuff to acquire the filename off the SD filesystem must be ok because the file name displayed has more than 8 characters and includes spaces, so it's likely just an issue with fitting it on the display.

Cheers,

Dear Zedsquared,

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.

Take a look at what's in repetier firmware. It DOES scroll for long file names.

How you display filenames is a compromise between readability when the name is long, and how many filenames you can fit on one screen. On PanelDue I use 2 columns:



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.

It's not as simple as it seems.

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.

2 Years later and this problem still persist, sadly.

For PanelDue, if the general consensus is that it would be better to have a single column of filenames so that longer names can be displayed, I'll change it.
