/**
 * Brainwave 1.0 pin assignments (AT90USB646)
 *
 * Requires hardware bundle for Arduino:
 * https://github.com/unrepentantgeek/brainwave-arduino
 */

/**
 *  Rev B  16 JAN 2017
 *
 *  Added pointer to a currently available Arduino IDE extension that will
 *  allow this board to use the latest Marlin software
 */

/**
 *  Rev C  2 JUN 2017
 *
 *  Converted to Arduino pin numbering
 */

/**
 *  Marlin_AT90USB - https://github.com/Bob-the-Kuhn/Marlin_AT90USB
 *    This is the only known IDE extension that is compatible with the pin definitions
 *    in this file, Adrduino 1.6.12 and the latest mainstream Marlin software.
 *
 *    "Marlin_AT90USB" makes 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.
 *
 *  Installation:
 *
 *    1. In the Arduino IDE, under Files -> Preferences paste the following URL
 *       https://rawgit.com/Bob-the-Kuhn/Marlin_AT90USB/master/package_MARLIN_AT90USB_index.json
 *    2. Under Tools > Board -> Boards manager, scroll to the bottom, click on MARLIN_AT90USB
 *       and then click on "Install"
 *    3. Select "AT90USB646_TEENSYPP" from the 'Tools > Board' menu.
 */

/**
 *  To burn the bootloader that comes with Marlin_AT90USB:
 *
 *    1. Connect your programmer to the board.
 *    2. In Arduino IDE select "AT90USB646_TEENSYPP" and then select the programmer.
 *    3. In 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.
