 /* 
  * Note: This program is derived from the SeeeStudioTFTv2 program.
  * Although both program share same ILI9341 TFT driver,
  * the touch sensor was not same with the Display I purchased from Akizuki.
  * http://akizukidenshi.com/catalog/g/gM-07747/
  * The touch sensor on the display is STMPE610,
  * so I hacked the minimum spi driver for it (polling mode only).
