00002  *
00003  * @note Just like the good old X11 eyes
00004  * @note this program stares at the point where
00005  * @note the TSI sensor of FRDM is being touched.
00006  * @note By touching the right most side of the sensor
00007  * @note program exits the staring loop and pretend to sleep.
00008  * @note Then touching the TFT starts the staring loop again.

00011 /*
00012  * Note: This program is derived from the SeeeStudioTFTv2 program.
00013  * Although both program share same ILI9341 TFT driver,
00014  * the touch sensor was not same with the Display I purchased from Akizuki.
00015  * http://akizukidenshi.com/catalog/g/gM-07747/
00016  * The touch sensor on the display is STMPE610,
00017  * so I hacked the minimum spi driver for it (polling mode only).
