/**
 * Anet V1.0 board pin assignments
 */

/**
 * Rev B    16 JUN 2017
 *
 * 1) no longer uses Sanguino files to define some of the pins
 * 2) added pointers to useable Arduino IDE extensions
 *
 */

/**
 * The standard Arduino IDE extension (board manager) for this board
 * is located at https://github.com/SkyNet3D/anet-board.
 *
 * Installation instructions are on that page.
 *
 * After copying the files to the appropriate location, restart Arduino and
 * you'll see "Anet V1.0" and "Anet V1.0 (Optiboot)" in the boards list.
 *
 * "Anet V1.0" uses the bootloader that was installed on the board when
 * it shipped from the factory.
 *
 * "Anet V1.0 (Optiboot)" frees up another 3K of FLASH.  You'll need to burn
 * a new bootloader to the board to be able to automatically download a
 * compiled image.
 *
 */

/**
 * Another usable Arduino IDE extension (board manager) can be found at
 * https://github.com/Lauszus/Sanguino
 *
 * This extension has been tested on Arduino 1.6.12 & 1.8.0
 *
 * Here's the JSON path:
 * https://raw.githubusercontent.com/Lauszus/Sanguino/master/package_lauszus_sanguino_index.json
 *
 * When installing select 1.0.2
 *
 * Installation instructions can be found at https://learn.sparkfun.com/pages/CustomBoardsArduino
 * Just use the above JSON URL instead of Sparkfun's JSON.
 *
 * Once installed select the Sanguino board and then select the CPU.
 *
 */

/**
 *  To burn a new bootloader:
 *
 *   1. Connect your programmer to the board.
 *   2. In the Arduino IDE select the board 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.
