[Request] SDHxC - On the fly floppy disk creation

Post by Godzil »

Hello everyone,

I just got a SD HxC (rev B) from a friend that give me, I started to investigate this marvelous board, but I can't find something that seems important for me (and maybe everyone)

We can't create blank floppy images on the fly on the SDHxC device, removing the SD card from the SDHxC, plug it in a computer, create an empty disk image, is not a quick process, and beeing able to do it directly on the SDHxC would be marvelous!

Not possible on Rev B hardware.

Maybe possible on Rev C hardware but not implemented.

Basically to do this you need a more expensive hardware...

So Maybe later on the next HxC (re) evolution ;)

To create an empty file with a header? Or it is only due to the "GUI" that need to be added?

To add and alloc an file on a FAT32 file system you need some memory buffer and cache...
And actually the 64KB PIC flash memory is almost full. (left ~512bytes...).

Yup, your right, I just think about this.

Thanks
