/* Button Code Definitions for xDuoo X3 target */


/* NOTE X3 Button system
 * The x3 has an interesting button layout. Multiple key presses are
 * NOT supported unless [BUTTON_POWER] is one of the combined keys
 * as you can imagine this causes problems as the power button takes
 * precedence in the button system and initiates a shutdown if the
 * key is held too long
 * instead of BUTTON_POWER use BUTTON_PWRALT in combination with other keys
 * IF using as a prerequsite button then BUTTON_POWER should be used
 *
 * Multiple buttons are emulated by button_read_device but there are a few
 * caveats to be aware of:
 *
 * Button Order Matters!
 *  different keys have different priorities, higher priority keys 'overide' the
 *  lower priority keys
 * VOLUP[7] VOLDN[6] PREV[5] NEXT[4] PLAY[3] OPTION[2] HOME[1]
 *
 * There will be no true release or repeat events, the user can let off the button
 *  pressed initially and it will still continue to appear to be pressed as long as
 *  the second key is held
 * */
