uMMC Firmware Beta ReleaseWe've got a new firmware to test out. Please feel free to try it out. uMMC Firmware Beta 102-08-b004 If you have any questions, send an email to support @ roguerobotics.com Documentation can be found here: http://www.roguerobotics.com/wikidocs/
Features
========
FAT12, FAT16, FAT32:
- All FAT formats are supported (that means cards from 1MB up to 8TB - yes 8TB -
268,435,445 clusters max @ 32KB/cluster - once we support SDXC,
we can address up to 2TB of space)
MMC, SDC, and SDHC:
- We now support SDHC cards. That means you can use your 32GB SDHC card in your project.
(SDHC maximum card size is 32GB)
microSD and miniSD support (with adapters)
RTC:
- RTC built-in. Requires setting after start.
- File times are updated with current time.
Configuration on card:
- Settings stored in /UMMC.CFG are read in on start.
- One setting per line.
e.g. D5
R5
L1
Random writes:
- You can write to any location in a file.
New open mode - "RW" mode:
- Files can now be opened in RW mode, so you can read, as well as write data.
File attributes:
- File attributes can be set/cleared.
File seek:
- Used for jumping around in a file for reading or writing.
- You can use the file seek (jump) to pre-allocate files for quicker writing.
File truncation:
- Used to truncate a file.
File listing (two modes):
- 1) original format (e.g. [D|num] name)
- 2) new format with dates/attributes
Change file timestamp:
- Set file timestamps to anything you want.
Readline command:
- Read from a file, one line at a time.
Writeline command:
- Write until end of line.
- Configurable terminator: just CR, just LF, or CR/LF.
File copy:
- Copy data from one file to another directly.
- Configurable copy progress status.

COMMAND LIST (* = new, ! = updated/new features)
=====
*A - set attributes "A +|- A|H|R|S path"
*B - copy file "B fh1 fh2 [num]"
C - close file "C fh"
*D - change timestamp "D year month day hour min sec path"
E - erase file/directory "E path"
F - free file "F"
I - file info "I fh"
*J - file jump/seek "J fh addr|E" (E = end)
!K - CSD/CID "K [B|I]" (new: "I" - gets more info from card)
L - list file/directory "L [path]"
M - make directory "M path"
*N - rename file/directory "N path|newpath"
!O - open file "O fh r|w|a|rw path" (new: "rw" mode)
!Q - query volume "Q [A]" (new: "A" - lists FS type)
R - read file "R fh [num] [addr]"
*RL - read line "RL fh [num] [addr]" (see "E" setting for EOL handling)
S - settings "S setting [value]"
*T - get/set time "T [yr [m [d [h [m [s]]]]]]"
*U - truncate at position "U fh"
V - version "V"
W - write file "W fh [num]"
*WL - write line "WL fh" (check "E" setting for end of line handling)
!Z - card/file status "Z [fh]" (new: "Z fh" - OK or EOF)
=====
