If not, see <http://www.gnu.org/licenses/>.**//*** Rev C 2 JUN 2017** 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** 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* 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:** 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.*//*** SILKSCREEN ERROR** The silkscreen for the endstops do NOT match the schematic. The silkscreen SHOULD* read (from left to right) X-STOP, Y-STOP, Z-STOP & E-STOP. The silkscreen actually* reads E-STOP, X-STOP, Y-STOP & Z-STOP.** The pin assignments in this file match the silkscreen.*/#if !defined(__AVR_AT90USB1286__) && !defined(__AVR_AT90USB1286P__)#error "Oops!
