file name Limitations

[clear-sky]

hi dear György Kovács
and thanks for your nice code!
a question!
why file name must have 8 capitalized char ?
is there any way to solve this Limitations?
as far as i know sd cards dos not have this limitation.

Hi, @clear-sky . The chip are support the so-called MS-DOS-compatible short file name in 8.3 format. It is also possible to implement long filename support, but I do not find information on this in the incomplete (difficult to understand) documentation

Hi dear @djuseeq . After much searching, I was able to find examples cited in the datasheet, such as: " 8.4.10. Operation lower-case file name and long file name, please refer to the explain of example EXAM11 "
library-->BOSSEN_USB_FOR_WT
All the examples mentioned in Datasheet are in this library, but the problem is that they are not suitable for Arduino, and I tried my best to match them with Arduino , but didn't.
I will enclose everything I have integrated with your library so that you can correct its problems if possible (pray for me if the structure I created made you laugh)
my edited library-->Ch376msc.zip

That will not works in this way :( . I will check the source you attached.

Thanx dear @djuseeq

Hi is there any update with this? This chip seems to be the first choice to be used with all the arduino family

Hi!

Any chance to have Long Filename Support? https://openbuilds.com/threads/interface-cnc-touch-controller.16906/page-11#post-129152 refers

The CH376 does support long file names. It is specifically mentioned in the specs. It may just be a limitation for writing files.

"Provide file management functions: open, create or delete files, enumerate and search files, create subdirectories, support long file names;"

Their doc specifies an example "EXAM1" for long file names, which I cannot seem to find on their site...

this could be a very interesting addition to the library, indeed.
Any chance there is some good news about it?
