30 /**
31  * There are two Arduino IDE extensions that are compatible with this board
32  * and with the mainstream Marlin software.
33  *
34  * Teensyduino - http://www.pjrc.com/teensy/teensyduino.html
35  * Select Teensy++ 2.0 in Arduino IDE from the 'Tools > Board' menu
36  *
37  * Installation instructions are at the above URL. Don't bother loading the
38  * libraries - they are not used with the Marlin software.
39  *
40  * Printrboard - https://github.com/scwimbush/Printrboard-HID-Arduino-IDE-Support
41  *
42  * Installation:
43  *
44  * 1. Go to the above URL, click on the "Clone or Download" button and then
45  * click on "Download ZIP" button.
46  * 2. Unzip the file, find the "printrboard" directory and then copy it to the
47  * hardware directory in Arduino. The Arduino hardware directory will probably
48  * be located in a path similar to this: C:\Program Files (x86)\Arduino\hardware.
49  * 3. Restart Arduino.
50  * 4. Select "Printrboard" from the 'Tools > Board' menu.
51  *
52  * Teensyduino is the most popular option. Printrboard is used if your board doesn't have
53  * the Teensyduino bootloader on it.
54  */

56 /**
57  * To burn the bootloader that comes with Printrboard:
58  *
59  * 1. Connect your programmer to the board.
60  * 2. In the Arduino IDE select "Printrboard" and then select the programmer.
61  * 3. In the Arduino IDE click on "burn bootloader". Don't worry about the "verify failed at 1F000" error message.
62  * 4. The programmer is no longer needed. Remove it.

65 /**
66  * Teensy++ 2.0 Breadboard pin assignments (AT90USB1286)
67  * Requires the Teensyduino software with Teensy++ 2.0 selected in Arduino IDE!
68  * http://www.pjrc.com/teensy/teensyduino.html
