/** TS_Eyes 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).
