/**

/**
 *  There are two Arduino IDE extensions that are compatible with this board
 *  and with the mainstream Marlin software.
 *
 *  Teensyduino - https://www.pjrc.com/teensy/teensyduino.html
 *    Select Teensy++ 2.0 in Arduino IDE from the 'Tools > Board' 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 > Board' 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.
