+ A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
+ The servos are pulsed in the background using the value most recently written using the write() method
+
+ Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
+ Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
+
+ The methods are:
+
+ Servo - Class for manipulating servo motors connected to Arduino pins.
+
+ attach(pin )  - Attaches a servo motor to an i/o pin.
+ attach(pin, min, max  ) - Attaches to a pin setting min and max values in microseconds
+ default min is 544, max is 2400
+
+ write()     - Sets the servo angle in degrees.  (invalid angle that is valid as pulse in microseconds is treated as microseconds)
+ writeMicroseconds() - Sets the servo pulse width in microseconds
+ read()      - Gets the last written servo pulse width as an angle between 0 and 180.
+ readMicroseconds()   - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
+ attached()  - Returns true if there is a servo attached.
+ detach()    - Stops an attached servos from pulsing its i/o pin.

+/*
+
+  A servo is activated by creating an instance of the Servo class passing the desired pin to the attach() method.
+  The servos are pulsed in the background using the value most recently written using the write() method
+
+  Note that analogWrite of PWM on pins associated with the timer are disabled when the first servo is attached.
+  Timers are seized as needed in groups of 12 servos - 24 servos use two timers, 48 servos will use four.
+  The sequence used to sieze timers is defined in timers.h
+
+  The methods are:
+
+   Servo - Class for manipulating servo motors connected to Arduino pins.
+
+   attach(pin )  - Attaches a servo motor to an i/o pin.
+   attach(pin, min, max  ) - Attaches to a pin setting min and max values in microseconds
+   default min is 544, max is 2400
+
+   write()     - Sets the servo angle in degrees.  (invalid angle that is valid as pulse in microseconds is treated as microseconds)
+   writeMicroseconds() - Sets the servo pulse width in microseconds
+   read()      - Gets the last written servo pulse width as an angle between 0 and 180.
+   readMicroseconds()   - Gets the last written servo pulse width in microseconds. (was read_us() in first release)
+   attached()  - Returns true if there is a servo attached.
+   detach()    - Stops an attached servos from pulsing its i/o pin.

-WARNING: 
---------
-THIS IS RELEASE CANDIDATE 2 FOR MARLIN 1.0.0
-
-The configuration is now split in two files
-Configuration.h for the normal settings
-Configuration_adv.h for the advanced settings
-
-Gen7T is not supported.
-
-Quick Information
-===================
-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. Sonney Jeon (Chamnit) improved some parts of grbl
-A fork by bkubicek for the Ultimaker was merged, and further development was aided by him.
-Some features have been added by:
-Lampmaker, 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
-*   SD Card support
-*   SD Card folders (works in pronterface)
-*   SD Card autostart support
-*   LCD support (ideally 20x4) 
-*   LCD menu system for autonomous SD card printing, controlled by an click-encoder. 
-*   EEPROM storage of e.g. max-velocity, max-acceleration, and similar variables
-*   many small but handy things originating from bkubicek's fork.
-*   Arc support
-*   Temperature oversampling
-*   Dynamic Temperature setpointing aka "AutoTemp"
-*   Support for QTMarlin, a very beta GUI for PID-tuning and velocity-acceleration testing. https://github.com/bkubicek/QTMarlin
-*   Endstop trigger reporting to the host software.
-*   Updated sdcardlib
-*   Heater power reporting. Useful for PID monitoring.
-*   PID tuning
-*   CoreXY kinematics (www.corexy.com/theory.html)
-*   Configurable serial port to support connection of wireless adaptors.
-
-The default baudrate is 250000. This baudrate has less jitter and hence errors than the usual 115200 baud, but is less supported by drivers and host-environments.
-
-
-Differences and additions to the already good Sprinter firmware:
-================================================================
-
-*Look-ahead:*
-
-Marlin has look-ahead. While sprinter has to break and re-accelerate at each corner, 
-lookahead will only decelerate and accelerate to a velocity, 
-so that the change in vectorial velocity magnitude is less than the xy_jerk_velocity.
-This is only possible, if some future moves are already processed, hence the name. 
-It leads to less over-deposition at corners, especially at flat angles.
-
-*Arc support:*
-
-Slic3r can find curves that, although broken into segments, were ment to describe an arc.
-Marlin is able to print those arcs. The advantage is the firmware can choose the resolution,
-and can perform the arc with nearly constant velocity, resulting in a nice finish. 
-Also, less serial communication is needed.
-
-*Temperature Oversampling:*
-
-To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.
-
-*AutoTemp:*
-
-If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly.
-Usually, higher speed requires higher temperature.
-This can now be performed by the AutoTemp function
-By calling M109 S<mintemp> T<maxtemp> F<factor> you enter the autotemp mode.
-
-You can leave it by calling M109 without any F.
-If active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec].
-The wanted temperature then will be set to t=tempmin+factor*maxerate, while being limited between tempmin and tempmax.
-If the target temperature is set manually or by gcode to a value less then tempmin, it will be kept without change.
-Ideally, your gcode can be completely free of temperature controls, apart from a M109 S T F in the start.gcode, and a M109 S0 in the end.gcode.
-
-*EEPROM:*
-
-If you know your PID values, the acceleration and max-velocities of your unique machine, you can set them, and finally store them in the EEPROM.
-After each reboot, it will magically load them from EEPROM, independent what your Configuration.h says.
-
-*LCD Menu:*
-
-If your hardware supports it, you can build yourself a LCD-CardReader+Click+encoder combination. It will enable you to realtime tune temperatures,
-accelerations, velocities, flow rates, select and print files from the SD card, preheat, disable the steppers, and do other fancy stuff.
-One working hardware is documented here: http://www.thingiverse.com/thing:12663 
-Also, with just a 20x4 or 16x2 display, useful data is shown.
-
-*SD card folders:*
-
-If you have an SD card reader attached to your controller, also folders work now. Listing the files in pronterface will show "/path/subpath/file.g".
-You can write to file in a subfolder by specifying a similar text using small letters in the path.
-Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".
-
-*SD card folders:*
-
-If you place a file auto[0-9].g into the root of the sd card, it will be automatically executed if you boot the printer. The same file will be executed by selecting "Autostart" from the menu.
-First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.
-
-*Endstop trigger reporting:*
-
-If an endstop is hit while moving towards the endstop, the location at which the firmware thinks that the endstop was triggered is outputed on the serial port.
-This is useful, because the user gets a warning message.
-However, also tools like QTMarlin can use this for finding acceptable combinations of velocity+acceleration.
-
-*Coding paradigm:*
-
-Not relevant from a user side, but Marlin was split into thematic junks, and has tried to partially enforced private variables.
-This is intended to make it clearer, what interacts which what, and leads to a higher level of modularization.
-We think that this is a useful prestep for porting this firmware to e.g. an ARM platform in the future.
-A lot of RAM (with enabled LCD ~2200 bytes) was saved by storing char []="some message" in Program memory.
-In the serial communication, a #define based level of abstraction was enforced, so that it is clear that
-some transfer is information (usually beginning with "echo:"), an error "error:", or just normal protocol,
-necessary for backwards compatibility.
-
-*Interrupt based temperature measurements:*
-
-An interrupt is used to manage ADC conversions, and enforce checking for critical temperatures.
-This leads to less blocking in the heater management routine.
-
-
-Non-standard M-Codes, different to an old version of sprinter:
-==============================================================
-Movement:
-
-*   G2  - CW ARC
-*   G3  - CCW ARC
-
-General:
-
-*   M17  - Enable/Power all stepper motors. Compatibility to ReplicatorG.
-*   M18  - Disable all stepper motors; same as M84.Compatibility to ReplicatorG.
-*   M30  - Print time since last M109 or SD card start to serial
-*   M42  - Change pin status via gcode
-*   M80  - Turn on Power Supply
-*   M81  - Turn off Power Supply
-*   M114 - Output current position to serial port 
-*   M119 - Output Endstop status to serial port
-
-Movement variables:
-
-*   M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
-*   M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
-*   M204 - Set default acceleration: S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2  also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate
-*   M206 - set home offsets.  This sets the X,Y,Z coordinates of the endstops (and is added to the {X,Y,Z}_HOME_POS configuration options (and is also added to the coordinates, if any, provided to G82, as with earlier firmware)
-*   M220 - set build speed mulitplying S:factor in percent ; aka "realtime tuneing in the gcode". So you can slow down if you have islands in one height-range, and speed up otherwise.
-*   M221 - set the extrude multiplying S:factor in percent
-*   M400 - Finish all buffered moves.
-
-Temperature variables:
-*   M301 - Set PID parameters P I and D
-*   M302 - Allow cold extrudes
-*   M303 - PID relay autotune S<temperature> sets the target temperature. (default target temperature = 150C)
-
-Advance:
-
-*   M200 - Set filament diameter for advance
-*   M205 - advanced settings:  minimum travel speed S=while printing T=travel only,  B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk
-
-EEPROM:
-
-*   M500 - stores paramters in EEPROM. This parameters are stored:  axis_steps_per_unit,  max_feedrate, max_acceleration  ,acceleration,retract_acceleration,
-  minimumfeedrate,mintravelfeedrate,minsegmenttime,  jerk velocities, PID
-*   M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).  
-*   M502 - reverts to the default "factory settings".  You still need to store them in EEPROM afterwards if you want to.
-*   M503 - print the current settings (from memory not from eeprom)
-
-MISC:
-
-*   M240 - Trigger a camera to take a photograph
-*   M999 - Restart after being stopped by error
-
-Configuring and compilation:

+*   Support for QTMarlin, a very beta GUI for PID-tuning and velocity-acceleration testing. https://github.com/bkubicek/QTMarlin
+*   Endstop trigger reporting to the host software.
+*   Updated sdcardlib
+*   Heater power reporting. Useful for PID monitoring.

+
+The default baudrate is 250000. This baudrate has less jitter and hence errors than the usual 115200 baud, but is less supported by drivers and host-environments.
+
+
+Differences and additions to the already good Sprinter firmware:
+================================================================
+
+*Look-ahead:*
+
+Marlin has look-ahead. While sprinter has to break and re-accelerate at each corner, 
+lookahead will only decelerate and accelerate to a velocity, 
+so that the change in vectorial velocity magnitude is less than the xy_jerk_velocity.
+This is only possible, if some future moves are already processed, hence the name. 
+It leads to less over-deposition at corners, especially at flat angles.
+
+*Arc support:*
+
+Slic3r can find curves that, although broken into segments, were ment to describe an arc.
+Marlin is able to print those arcs. The advantage is the firmware can choose the resolution,
+and can perform the arc with nearly constant velocity, resulting in a nice finish. 
+Also, less serial communication is needed.
+
+*Temperature Oversampling:*
+
+To reduce noise and make the PID-differential term more useful, 16 ADC conversion results are averaged.
+
+*AutoTemp:*
+
+If your gcode contains a wide spread of extruder velocities, or you realtime change the building speed, the temperature should be changed accordingly.
+Usually, higher speed requires higher temperature.
+This can now be performed by the AutoTemp function
+By calling M109 S<mintemp> T<maxtemp> F<factor> you enter the autotemp mode.
+
+You can leave it by calling M109 without any F.
+If active, the maximal extruder stepper rate of all buffered moves will be calculated, and named "maxerate" [steps/sec].
+The wanted temperature then will be set to t=tempmin+factor*maxerate, while being limited between tempmin and tempmax.
+If the target temperature is set manually or by gcode to a value less then tempmin, it will be kept without change.
+Ideally, your gcode can be completely free of temperature controls, apart from a M109 S T F in the start.gcode, and a M109 S0 in the end.gcode.
+
+*EEPROM:*
+
+If you know your PID values, the acceleration and max-velocities of your unique machine, you can set them, and finally store them in the EEPROM.
+After each reboot, it will magically load them from EEPROM, independent what your Configuration.h says.
+
+*LCD Menu:*
+
+If your hardware supports it, you can build yourself a LCD-CardReader+Click+encoder combination. It will enable you to realtime tune temperatures,
+accelerations, velocities, flow rates, select and print files from the SD card, preheat, disable the steppers, and do other fancy stuff.
+One working hardware is documented here: http://www.thingiverse.com/thing:12663 
+Also, with just a 20x4 or 16x2 display, useful data is shown.
+
+*SD card folders:*
+
+If you have an SD card reader attached to your controller, also folders work now. Listing the files in pronterface will show "/path/subpath/file.g".
+You can write to file in a subfolder by specifying a similar text using small letters in the path.
+Also, backup copies of various operating systems are hidden, as well as files not ending with ".g".
+
+*SD card folders:*
+
+If you place a file auto[0-9].g into the root of the sd card, it will be automatically executed if you boot the printer. The same file will be executed by selecting "Autostart" from the menu.
+First *0 will be performed, than *1 and so on. That way, you can heat up or even print automatically without user interaction.
+
+*Endstop trigger reporting:*
+
+If an endstop is hit while moving towards the endstop, the location at which the firmware thinks that the endstop was triggered is outputed on the serial port.
+This is useful, because the user gets a warning message.
+However, also tools like QTMarlin can use this for finding acceptable combinations of velocity+acceleration.
+
+*Coding paradigm:*
+
+Not relevant from a user side, but Marlin was split into thematic junks, and has tried to partially enforced private variables.
+This is intended to make it clearer, what interacts which what, and leads to a higher level of modularization.
+We think that this is a useful prestep for porting this firmware to e.g. an ARM platform in the future.
+A lot of RAM (with enabled LCD ~2200 bytes) was saved by storing char []="some message" in Program memory.
+In the serial communication, a #define based level of abstraction was enforced, so that it is clear that
+some transfer is information (usually beginning with "echo:"), an error "error:", or just normal protocol,
+necessary for backwards compatibility.
+
+*Interrupt based temperature measurements:*
+
+An interrupt is used to manage ADC conversions, and enforce checking for critical temperatures.
+This leads to less blocking in the heater management routine.
+
+
+Non-standard M-Codes, different to an old version of sprinter:
+==============================================================
+Movement:
+
+*   G2  - CW ARC
+*   G3  - CCW ARC
+
+General:
+
+*   M17  - Enable/Power all stepper motors. Compatibility to ReplicatorG.
+*   M18  - Disable all stepper motors; same as M84.Compatibility to ReplicatorG.
+*   M30  - Print time since last M109 or SD card start to serial
+*   M42  - Change pin status via gcode
+*   M80  - Turn on Power Supply
+*   M81  - Turn off Power Supply
+*   M114 - Output current position to serial port 
+*   M119 - Output Endstop status to serial port
+
+Movement variables:
+
+*   M202 - Set max acceleration in units/s^2 for travel moves (M202 X1000 Y1000) Unused in Marlin!!
+*   M203 - Set maximum feedrate that your machine can sustain (M203 X200 Y200 Z300 E10000) in mm/sec
+*   M204 - Set default acceleration: S normal moves T filament only moves (M204 S3000 T7000) im mm/sec^2  also sets minimum segment time in ms (B20000) to prevent buffer underruns and M20 minimum feedrate
+*   M206 - set home offsets.  This sets the X,Y,Z coordinates of the endstops (and is added to the {X,Y,Z}_HOME_POS configuration options (and is also added to the coordinates, if any, provided to G82, as with earlier firmware)
+*   M220 - set build speed mulitplying S:factor in percent ; aka "realtime tuneing in the gcode". So you can slow down if you have islands in one height-range, and speed up otherwise.
+*   M221 - set the extrude multiplying S:factor in percent
+*   M400 - Finish all buffered moves.
+
+Temperature variables:
+*   M301 - Set PID parameters P I and D
+*   M302 - Allow cold extrudes
+*   M303 - PID relay autotune S<temperature> sets the target temperature. (default target temperature = 150C)
+
+Advance:
+
+*   M200 - Set filament diameter for advance
+*   M205 - advanced settings:  minimum travel speed S=while printing T=travel only,  B=minimum segment time X= maximum xy jerk, Z=maximum Z jerk

+*   M501 - reads parameters from EEPROM (if you need reset them after you changed them temporarily).  
+*   M502 - reverts to the default "factory settings".  You still need to store them in EEPROM afterwards if you want to.
+*   M503 - print the current settings (from memory not from eeprom)
+
+MISC:
+
+*   M240 - Trigger a camera to take a photograph
