SD - a slightly more friendly wrapper for sdfatlib
This library aims to expose a subset of SD card functionality
in the form of a higher level "wrapper" object.
License: GNU General Public License V3
(Because sdfatlib is licensed with this.)
(C) Copyright 2010 SparkFun Electronics
This library provides four key benefits:
* Including `SD.h` automatically creates a global
`SD` object which can be interacted with in a similar
manner to other standard global objects like `Serial` and `Ethernet`.
* Boilerplate initialisation code is contained in one method named
`begin` and no further objects need to be created in order to access
the SD card.
* Calls to `open` can supply a full path name including parent
directories which simplifies interacting with files in subdirectories.
* Utility methods are provided to determine whether a file exists
and to create a directory heirarchy.
Note however that not all functionality provided by the underlying
sdfatlib library is exposed.
*/
/*
Implementation Notes
In order to handle multi-directory path traversal, functionality that
requires this ability is implemented as callback functions.
Individual methods call the `walkPath` function which performs the actual
directory traversal (swapping between two different directory/file handles
along the way) and at each level calls the supplied callback function.
Some types of functionality will take an action at each level (e.g. exists
or make directory) which others will only take an action at the bottom
level (e.g. open).
*/

char *buffer) {
/*
Parse individual path components from a path.
e.g. after repeated calls '/foo/bar/baz' will be split
into 'foo', 'bar', 'baz'.
This is similar to `strtok()` but copies the component into the
supplied buffer rather than modifying the original string.
`buffer` needs to be PATH_COMPONENT_BUFFER_LEN in size.
`p_offset` needs to point to an integer of the offset at
which the previous path component finished.
Returns `true` if more components remain.
Returns `false` if this is the last component.
(This means path ended with 'foo' or 'foo/'.)

this function traverses the directories in the path and at each

the supplied object for context if required.
e.g. given the path '/foo/bar/baz'
the callback would be called at the equivalent of
'/foo', '/foo/bar' and '/foo/bar/baz'.
The implementation swaps between two different directory/file
handles as it traverses the directories and does not use recursion
in an attempt to use memory efficiently.
If a callback wishes to stop the directory traversal it should
return false--in this case the function will stop the traversal,
tidy up and return false.
If a directory path doesn't exist at some point this function will
also return false and not subsequently call the callback.
If a directory path specified is complete, valid and the callback
did not indicate the traversal should be interrupted then this
function will return true.

\section Intro Introduction
The Arduino SdFat Library is a minimal implementation of FAT16 and FAT32
file systems on SD flash memory cards. Standard SD and high capacity
SDHC cards are supported.
The SdFat only supports short 8.3 names.
The main classes in SdFat are Sd2Card, SdVolume, and SdFile.
The Sd2Card class supports access to standard SD cards and SDHC cards. Most
applications will only need to call the Sd2Card::init() member function.
The SdVolume class supports FAT16 and FAT32 partitions. Most applications
will only need to call the SdVolume::init() member function.
The SdFile class provides file access functions such as open(), read(),
remove(), write(), close() and sync(). This class supports access to the root
directory and subdirectories.
A number of example are provided in the SdFat/examples folder. These were
developed to test SdFat and illustrate its use.
SdFat was developed for high speed data recording. SdFat was used to implement
an audio record/play class, WaveRP, for the Adafruit Wave Shield. This
application uses special Sd2Card calls to write to contiguous files in raw mode.
These functions reduce write latency so that audio can be recorded with the
small amount of RAM in the Arduino.
\section SDcard SD\SDHC Cards
Arduinos access SD cards using the cards SPI protocol. PCs, Macs, and
most consumer devices use the 4-bit parallel SD protocol. A card that
functions well on A PC or Mac may not work well on the Arduino.
Most cards have good SPI read performance but cards vary widely in SPI
write performance. Write performance is limited by how efficiently the
card manages internal erase/remapping operations. The Arduino cannot
optimize writes to reduce erase operations because of its limit RAM.
SanDisk cards generally have good write performance. They seem to have
more internal RAM buffering than other cards and therefore can limit
the number of flash erase operations that the Arduino forces due to its
limited RAM.
\section Hardware Hardware Configuration
SdFat was developed using an
<A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
<A HREF = "http://www.ladyada.net/make/waveshield/"> Wave Shield</A>.
The hardware interface to the SD card should not use a resistor based level
shifter. SdFat sets the SPI bus frequency to 8 MHz which results in signal
rise times that are too slow for the edge detectors in many newer SD card
controllers when resistor voltage dividers are used.
The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
74HC4050N based circuit shown in the file SdLevel.png. The Adafruit Wave Shield
uses a 74AHC125N. Gravitech sells SD and MicroSD Card Adapters based on the
74LCX245.
If you are using a resistor based level shifter and are having problems try
setting the SPI bus frequency to 4 MHz. This can be done by using
card.init(SPI_HALF_SPEED) to initialize the SD card.
\section comment Bugs and Comments
If you wish to report bugs or have comments, send email to fat16lib@sbcglobal.net.
\section SdFatClass SdFat Usage
SdFat uses a slightly restricted form of short names.
Only printable ASCII characters are supported. No characters with code point
values greater than 127 are allowed. Space is not allowed even though space
was allowed in the API of early versions of DOS.
Short names are limited to 8 characters followed by an optional period (.)
and extension of up to 3 characters. The characters may be any combination
of letters and digits. The following special characters are also allowed:
$ % ' - _ @ ~ ` ! ( ) { } ^ # &
Short names are always converted to upper case and their original case
value is lost.
\note
The Arduino Print class uses character
at a time writes so it was necessary to use a \link SdFile::sync() sync() \endlink
function to control when data is written to the SD card.
\par
An application which writes to a file using \link Print::print() print()\endlink,
\link Print::println() println() \endlink
or \link SdFile::write write() \endlink must call \link SdFile::sync() sync() \endlink
at the appropriate time to force data and directory information to be written
to the SD Card. Data and directory information are also written to the SD card
when \link SdFile::close() close() \endlink is called.
\par
Applications must use care calling \link SdFile::sync() sync() \endlink
since 2048 bytes of I/O is required to update file and
directory information. This includes writing the current data block, reading
the block that contains the directory entry for update, writing the directory
block back and reading back the current data block.
It is possible to open a file with two or more instances of SdFile. A file may
be corrupted if data is written to the file by more than one instance of SdFile.
\section HowTo How to format SD Cards as FAT Volumes
You should use a freshly formatted SD card for best performance. FAT
file systems become slower if many files have been created and deleted.
This is because the directory entry for a deleted file is marked as deleted,
but is not deleted. When a new file is created, these entries must be scanned
before creating the file, a flaw in the FAT design. Also files can become
fragmented which causes reads and writes to be slower.
Microsoft operating systems support removable media formatted with a
Master Boot Record, MBR, or formatted as a super floppy with a FAT Boot Sector
in block zero.
Microsoft operating systems expect MBR formatted removable media
to have only one partition. The first partition should be used.
Microsoft operating systems do not support partitioning SD flash cards.
If you erase an SD card with a program like KillDisk, Most versions of
Windows will format the card as a super floppy.
The best way to restore an SD card's format is to use SDFormatter
which can be downloaded from:
http://www.sdcard.org/consumers/formatter/
SDFormatter aligns flash erase boundaries with file
system structures which reduces write latency and file system overhead.
SDFormatter does not have an option for FAT type so it may format
small cards as FAT12.
After the MBR is restored by SDFormatter you may need to reformat small
cards that have been formatted FAT12 to force the volume type to be FAT16.
If you reformat the SD card with an OS utility, choose a cluster size that
will result in:
4084 < CountOfClusters && CountOfClusters < 65525
The volume will then be FAT16.
If you are formatting an SD card on OS X or Linux, be sure to use the first
partition. Format this partition with a cluster count in above range.

* >>>> May include the 60Hz notch filter by Chip Audette <<<<
* >>>> SUPPORTS 16 CHANNELS WITH DAISY MODULE EXPANSION CARD <<<<
*
* This code is written to target a PIC32MX250F128B with UDB32-MX2-DIP bootloader
* To Program, user must manually reset the PIC32 on the OpenBCI 32bit Board
* press RST, then press PROG, then release RST, then release PROG
* press RST, then press PROG, then release RST, then release PROG
* Adjust as needed if you are testing on different hardware.
*
* Find the custom libraries here https://github.com/OpenBCI/OpenBCI_32bit_Libraries
* download and place the libraries inside your: User/Documents/Arduino/libraries folder.
*
* You need the latest version of the chipKIT-core hardware files.
* Go to the chipKIT website http://chipkit.net/
* or directly to their core Wiki http://chipkit.net/wiki/index.php?title=ChipKIT_core
* and follow the directions to install chipKIT board files into the latest Arduino IDE.
* Then, when you open up Arduino IDE, you can select 'OpenBCI 32' from the boards menu!
*
* Made by Joel Murphy, Luke Travis, Conor Russomanno Summer, 2014.
* Note that to USE the OpenBCI system, you will generally use the OpenBCI USB Dongle.
*The dongle requries that you install the FTDI drivers for your particular operating system:
* http://www.ftdichip.com/FTDrivers.htm
* Before you upload the firmware, you need to place the OpenBCI board variant files inside the mpide program folder:
* This will allow you to find the OpenBCI 32 board in mpide dropdown selection tree!
* Place the OpenBCI folder into the mpide application:
* On A Mac, right click the application mpide, and select 'Show Package Contents'
* place the entire OpenBCI folder in the variants folder here:
* Mpide/Contents/Resources/Java/hardware/pic32/variants
* On a Windows, place the entire OpenBCI folder in the variants folder here:
* C:\Program Files\mpide-blah\hardware\pic32\variants
* Remove the files OpenBCI_32 and SD from the OpenBCI_32_Library folder and put it in your documents/mpide/libraries folder.
* Put the OpenBCI_32_SD folder into your documents/mpide folder and restart mpide to be able to select the sketch.
* When you upload the firmware, select the 'OpenBCI 32' from the Tools -> Board -> chipKIT menu,
* Then select the serial port of the dongle, then press upload!
* We are uploading the sketch over air! There is a chance that the mpide will timeout during the upload process!
* If this happens, you will need to unplug the dongle, and re-insert it to stop the upload.
* Then, power cycle the OpenBCI board, as it is best that the Board radio comes on line after the dongle radio.
* Then try again to upload.
* This is a known issue, and we can confirm that all boards shipped will take the upload process,
* it just might take a couple of times to stick.
*
* Any SDcard code is based on RawWrite example in SDFat library
* Any SDcard code is based on RawWrite example in SDFat library
* ASCII commands are received on the serial port to configure and control
* Serial protocol uses '+' immediately before and after the command character
* We call this the 'burger' protocol. the '+' are the buns. Example:
* We call this the 'burger' protocol. the '+' re the buns. Example:
* To begin streaming data, send '+b+'
* The addition of the '+'s is handled by the RFduino radios in OpenBCI V3
* The OpenBCI Dongle firmware takes care of the burger protocol
*
* This software is provided as-is with no promise of workability
* Use at your own risk, wysiwyg.
* Made by Joel Murphy, Luke Travis, Conor Russomanno Summer, 2014.
