+ *  There are two Arduino IDE extensions that are compatible with this board
+ *  and with the mainstream Marlin software.
+ *
+ *  Teensyduino - http://www.pjrc.com/teensy/teensyduino.html
+ *    Select Teensy++ 2.0 in Arduino IDE from the 'Tools -> Boards' menu
+ *
+ *    Installation instructions are at the above URL.  Don't bother loading the
+ *    libraries - they are not used with the Marlin software.
+ *
+ *  Printrboard - https://github.com/scwimbush/Printrboard-HID-Arduino-IDE-Support
+ *
+ *    Installation:
+ *
+ *       1. Go to the above URL, click on the "Clone or Download" button and then
+ *          click on "Download ZIP" button.
+ *       2. Unzip the file, find the "printrboard" directory and then copy it to the
+ *          hardware directory in Arduino.  The Arduino hardware directory will probably
+ *          be located in a path similar to this: C:\Program Files (x86)\Arduino\hardware.
+ *       3. Restart Arduino.
+ *       4. Select "Printrboard" from the 'Tools -> Boards' menu.
+ *
+ *  Teensyduino is the most popular option. Printrboard is used if your board doesn't have
+ *  the Teensyduino bootloader on it.
+ */
+
+/**
+ *  To burn the bootloader that comes with Printrboard:
+ *
+ *   1. Connect your programmer to the board.
+ *   2. In the Arduino IDE select "Printrboard" and then select the programmer.
+ *   3. In the Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.
+ *   4. The programmer is no longer needed. Remove it.

+ *  There are two Arduino IDE extensions that are compatible with this board
+ *  and with the mainstream Marlin software.
+ *
+ *  Teensyduino - http://www.pjrc.com/teensy/teensyduino.html
+ *    Select Teensy++ 2.0 in Arduino IDE from the 'Tools -> Boards' menu
+ *
+ *    Installation instructions are at the above URL.  Don't bother loading the
+ *    libraries - they are not used with the Marlin software.
+ *
+ *  Printrboard - https://github.com/scwimbush/Printrboard-HID-Arduino-IDE-Support
+ *
+ *    Installation:
+ *
+ *       1. Go to the above URL, click on the "Clone or Download" button and then
+ *          click on "Download ZIP" button.
+ *       2. Unzip the file, find the "printrboard" directory and then copy it to the
+ *          hardware directory in Arduino.  The Arduino hardware directory will probably
+ *          be located in a path similar to this: C:\Program Files (x86)\Arduino\hardware.
+ *       3. Restart Arduino.
+ *       4. Select "Printrboard" from the 'Tools -> Boards' menu.
+ *
+ *  Teensyduino is the most popular option. Printrboard is used if your board doesn't have
+ *  the Teensyduino bootloader on it.

+ *  To burn the bootloader that comes with Printrboard:
+ *
+ *   1. Connect your programmer to the board.
+ *   2. In the Arduino IDE select "Printrboard" and then select the programmer.
+ *   3. In the Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.

 /**
- *  rev B    30 DEC 2016
+ *  Rev C  2 JUN 2017
  *
- *  The original version of this file did NOT result in a useful program because:
- *   1. The pin numbers assumed that the "#define AT90USBxx_TEENSYPP_ASSIGNMENTS" line
- *      in FASTIO.h was commented out. There wasn't an Arduino IDE 1.6.x extension/package
- *      that supported this pin map so the latest Marlin wouldn't compile.
- *   2. The silkscreen for the four end stops don't agree with the schematic. Activating
- *      the X endstop would tell the software that the Y endstop just went active.
- *   3. The thermistor inputs also had heater names assigned to them. The result was
- *      thermistor inputs that were set to digital outputs.
+ *  Converted to Arduino pin numbering
+ */
+
+/**
+ *  There are two Arduino IDE extensions that are compatible with this board
+ *  and with the mainstream Marlin software.  All have been used with Arduino 1.6.12
+ *
+ *  Teensyduino - http://www.pjrc.com/teensy/teensyduino.html
+ *    Select Teensy++ 2.0 in Arduino IDE from the 'Tools -> Boards' menu
  *
- *  Rev B corrects the above problems by:
- *   1. The "Marlin_AT90USB" extension/package was developed.  This extension enables the
- *      latest Marlin software to compile using Arduino IDE 1.6.x and 1.80.
- *   2. The endstop pin numbers in this file were changed to match the silkscreen.  This
- *      makes it a little confusing when trying to correlate the schematic with the pin
- *      numbers used in this file.
- *   3. The offending heater names were deleted.
+ *    Installation instructions are at the above URL.  Don't bother loading the
+ *    libraries - they are not used with the Marlin software.
  *
- *  To create a useable image for Teensylu do the following:
- *   a) Install the Marlin_AT90USB extension with either of the following methods:
- *        Automatic - paste this URL into preferences and then use Boards manager
- *            https://rawgit.com/Bob-the-Kuhn/Marlin_AT90USB/master/package_MARLIN_AT90USB_index.json
- *        Manual:
- *           1. Copy the following URL into Go to "https://github.com/Bob-the-Kuhn/Marlin_AT90USB",
- *              click on the "Clone or Download" button and then click on "Download ZIP" button.
- *           2. Unzip the file, find the "Marlin_AT90USB" directory and then copy it to the
- *              hardware directory in Arduino.  The Arduino hardware directory will probably be
- *              located in a path similar to this: C:\Program Files (x86)\Arduino\hardware
- *   b) Connect the USBtinyISP to the board.
- *   c) In the Arduino IDE select the "AT90USB1286_STANDARD" board in the of the "Marlin_AT90USB"
- *      section and select the "USBtinyISP" programmer.
- *   d) In the Arduino IDE click on "burn bootloader".  Don't worry about the "verify
- *      failed at 1F000" error message.
- *   e) The USBtinyISP programmer is no longer needed.  Remove it.
- *   f) In FASTIO.h comment out the "#define AT90USBxx_TEENSYPP_ASSIGNMENTS" line.
- *   g) To upload a sketch do the following:
- *       1. remove the jumper
- *       2. press reset
- *       3. click on the "upload" button in the Arduino IDE
- *       4. wait until the upload finishes (less than a minute)
- *       5. put the jumper back on
- *       6. press the reset button
+ *  Printrboard - https://github.com/scwimbush/Printrboard-HID-Arduino-IDE-Support
+ *    This is basically Teensyduino but with a bootloader that can handle image sizes
+ *    larger than 64K.
  *
+ *    Installation:
+ *
+ *       1. Go to the above URL, click on the "Clone or Download" button and then
+ *          click on "Download ZIP" button.
+ *       2. Unzip the file, find the "printrboard" directory and then copy it to the
+ *          hardware directory in Arduino.  The Arduino hardware directory will probably
+ *          be located in a path similar to this: C:\Program Files (x86)\Arduino\hardware.
+ *       3. Restart Arduino.
+ *       4. Select "Printrboard" from the 'Tools -> Boards' menu.
+ *
+ *  Teensyduino is the most popular option. Printrboard is used if your board doesn't have
+ *  the Teensyduino bootloader on it.
+ */
+
+/**
+ *  To burn the bootloader that comes with Printrboard:
  *
- *  NOTE - the "Marlin_AT90USB" pin maps make PWM0A available rather than the usual PWM1C.
- *         These PWMs share the same physical pin. Marlin uses TIMER1 to generate
- *         interrupts and sets it up such that PWM1A, PWM1B & PWM1C can't be used.
+ *   1. Connect your programmer to the board.
+ *   2. In the Arduino IDE select "Printrboard" and then select the programmer.
+ *   3. In the Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.
+ *   4. The programmer is no longer needed. Remove it.
