/*
 * 'clock_2' とは？
 */

  NeoPixel 1/4 60 Ring (RGB タイプ)(adafruit) と LPC812 で、丸い LED 時計を
  作るためのファームウェアです。

  LPC812 を使うため CLKIN と ISP-sel が分離され起動失敗がなくなります。
  また 赤外リモコン IrT の使用をやめ 直接つないだスイッチで制御します。

    /*
     * I/O pin usage (LPC810+=2)
     *   pin#I3: PIO0_3 (output) - drive WS2812B (GPIO or SPI)
     *   pin#I5: PIO0_12 input   - SW input for control
     *   pin#O8: PIO0_1 (input)  - CLKIN from external X'tal
     */

/*
 * how to use ?
 */

  PIO0_12 につないだプッシュスイッチ一つを使い、長押し・短押しを使い分けて
  操作します。なお時刻は、電源を入れるたびに設定してください。
