Thanks, but that part in the readme doesn't explain much how to use the flash memory for fs20/fht traffic.
I would think the 2MB flash wold be used automatically by the CUNO as a buffer but the fact is that if a shutdown FHEM for an hour, I lose all information for that period.
Also there is no info about the microsd card, how to use it.
Any help is appreciated but there is no rush.

Do you have you're CUNO at work yet? I wonder if you already have some experience with the 2mb onboard and the microsd card. I've inserted a 1gb microsd card but so far no buffering is done. How can I tell if the card is working correctly? Do I have to format it?
Many questions, maybe you have an answer
Well i asked the question in the "fhem-users" google group, and this was the awnser i got:
Code: Select all
Note 1: Please post such messages in the cul_fans group.
Note 2: the MicroSD is not supported by culfw.
Note 3: Storing data on the 2mb flash is not really "foolproof", and I did not
tested it for over a year. It was a quick hack, designed to be used by
the CUR, since it needs an FS anyway for its menus.
Note 4: Currently I wont support it.
If you still want to spend some time:
Essentially you have to enable HAS_FS in board.h, and make sure that df_init,
fs_init and log_init is called in CUNO.c. And then you have to add the
read_file and write_file commands to the fntab in CUNO.c. You may have to enter
the correct pin numbers for DF_... in board.h
CUR.c may be your guide, but on the other hand I did not flashed the CUR for
over a year now and as there are only 3 prototypes, I don't think somebody
else did it either.
Not really satisfying but hey....... its working perfectly without. Maybe in the future
