/**
 *  rev B    30 DEC 2016
 *
 *  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.
 *
 *  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.
 *
 *  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
 *
 *
 *  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 not be used.

 /**
  *  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.
