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