+/** TS_Eye TSI sample program using Adafruit 2.8" TFT with Touch
+ *
+ * @note Just like the good old X11 eyes
+ * @note this program stares at the point where
+ * @note the TSI sensor of FRDM is being touched.
+ * @note By touching the right most side of the sensor
+ * @note program exits the staring loop and pretend to sleep.
+ * @note Then touching the TFT starts the staring loop again.
+ */
+ 
+ /* 
+  * 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).
