\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 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.

This firmware is a mashup between Sprinter, grbl and many original parts.
(https://github.com/kliment/Sprinter)
(https://github.com/simen/grbl/tree)
Features:
- Interrupt based movement with real linear acceleration
- High steprate
- Look ahead (Keep the speed high when possible. High cornering speed)
- Interrupt based temperature protection
- preliminary support for Matthew Roberts advance algorithm
For more info see: http://reprap.org/pipermail/reprap-dev/2011-May/003323.html
This firmware is optimized for gen6 electronics.
The default baudrate is 250000.
This gives less communication errors then regular baudrates.
========================================================================================
Configuring and compilation
Install the arduino software version 0018
http://www.arduino.cc/en/Main/Software
Install the sanguino software, version 0018
http://sanguino.cc/useit
Install pronterface
https://github.com/kliment/Printrun
Copy the Marlin firmware
https:/github.com/ErikZalm/Marlin
(Use the download button)
Start the arduino IDE.
Select Tools -> Board -> Sanguino
Select the correct serial port in Tools ->Serial Port
Open Marlin.pde
Change the printer specific setting in Configuration.h to the correct values.
The following values are the most important:
- float axis_steps_per_unit[].... // Set the correct steps / mm in the corresponding field
- const bool ENDSTOPS_INVERTING = false; // Change if only positive moves are executed
- #define INVERT_x_DIR true // Change if the motor direction is wrong
Click the Upload button
If all goes well the firmware is uploading
Start pronterface
Select the correct Serial Port. Type 250000 in the baudrate field.
Press the Connect button
===============================================================================================
Known issues
On some systems we get compilation errors.
This is caused by the "wiring_serial.c" and "wiring.c".
The simple fix is to delete these files but this may have a performance impact.
The best workaround is to move these files to sanguino directory.
(".../arduino-0018/hardware/Sanguino/cores/arduino/" on windows systems)
This RepRap firmware is a mashup between Sprinter, grbl and many original parts.
(https://github.com/kliment/Sprinter)
(https://github.com/simen/grbl/tree)
Derived from Sprinter and Grbl by Erik van der Zalm.
Sprinters lead developers are Kliment and caru.
Grbls lead developer is Simen Svale Skogsrud.
It has been adapted to the Ultimaker Printer by:
Bernhard Kubicek, Matthijs Keuper, Bradley Feldman, and others...
Features:
- Interrupt based movement with real linear acceleration
- High steprate
- Look ahead (Keep the speed high when possible. High cornering speed)
- Interrupt based temperature protection
- preliminary support for Matthew Roberts advance algorithm
For more info see: http://reprap.org/pipermail/reprap-dev/2011-May/003323.html
- Full endstop support
- Simple LCD support (16x2)
- SD Card support
- Provisions for Bernhard Kubicek's new hardware control console and 20x4 lcd
This firmware is optimized for Ultimaker's gen6 electronics (including the Ultimaker 1.5.x daughterboard and Arduino Mega 2560).
The default baudrate is 115200.

WARNING: THIS IN A PROCESS OF HEAVY OVERWORKING.
DO NOT USE THIS ON YOUR MACHINE UNTIL FURTHER NOTICE!!!
===========================================
This RepRap firmware is a mashup between <a href="https://github.com/kliment/Sprinter">Sprinter</a>, <a href="https://github.com/simen/grbl/tree">grbl</a> and many original parts.
Derived from Sprinter and Grbl by Erik van der Zalm.
Sprinters lead developers are Kliment and caru.
Grbls lead developer is Simen Svale Skogsrud.
Some features have been added by and configuration has been added by:
Bernhard Kubicek, Matthijs Keuper, Bradley Feldman, and others...
Features:
- Interrupt based movement with real linear acceleration
- High steprate
- Look ahead (Keep the speed high when possible. High cornering speed)
- Interrupt based temperature protection
- preliminary support for Matthew Roberts advance algorithm
For more info see: http://reprap.org/pipermail/reprap-dev/2011-May/003323.html
- Full endstop support
- Simple LCD support (16x2)
- SD Card support
- Provisions for Bernhard Kubicek's new hardware control console and 20x4 lcd
This firmware is optimized for Ultimaker's gen6 electronics (including the Ultimaker 1.5.x daughterboard and Arduino Mega 2560).
The default baudrate is 115200.
========================================================================================

files to compare manually:
planner.cpp
stepper.cpp
temperature.cpp
---
things that changed:
* planner.cpp
estimate_acc_distance now works with floats.
in calculate_trapezoid:for_block
long acceleration_rate=(long)((float)acceleration*8.388608) is gone
so is block_>acceleration_rate
void planner_reverse_pass:
some stuff I don't understand right now changed
in planner_forward_pass:
done: BLOCK_BUFFER_SIZE is now necessarily power of 2 (aka 8 16, 32). Inportant to document this somewhere.
no more inline in void plan_discard_current_block()
no more inline in plan_get_current_block()
in plan_buffer_line(...)
the long target[4]; and calculations of thoose should go after the while(block_buffer_tail==..). if the axis_steps_per_unit are changed from the gcode (M92) the calculation for the currently planned buffer move will be corrupt, because Target is calculated with one value, and the stuff afterwards with another. At least this solved the problem I had with the M92 E* changes in the code. Very sure about this, I took me 20min to find this as the solution for the bug I was hunting.
around if(feed_rate<minimumfeedrate) this only should be done if it is not a pure extrusion. I think there is a bug right now.
~line 447 blockcount=
not sure if this also works if the difference is negative, as it would happen if the ringbuffer runs over the end and start at 0.
~line 507 tmp_aceleration. not sure whats going on, but a lot changed.
* stepper.cpp
~214: if (busy) should be a echoln, maybe
~331: great, The Z_M_PIN checks are in :)
*temperature.cpp
done: enum for heater, bed,
manage_heater() is seriously different.
done: if tem_meas_ready ==true->!true+return?
done #define K1 0.95 maybe in the configuration.h?
semi-done: PID-C checking needed. Untested but added.
----
still needed to finish the merge, before testin!
manage_heater
ISR
movement planner
TODO:
remove traveling at maxpseed
remove Simplelcd
remove DEBUG_STEPS?
block_t
pid_dt ->0.1 whats the changes to the PID, checking needed
----
second merge saturday morning:
done: PID_dt->0.1
