Rhyme 0:0b7a110bfceb 1 /** TS_Eye TSI sample program using Adafruit 2.8" TFT with Touch
Rhyme 0:0b7a110bfceb 2 *
Rhyme 0:0b7a110bfceb 3 * @note Just like the good old X11 eyes
Rhyme 0:0b7a110bfceb 4 * @note this program stares at the point where
Rhyme 0:0b7a110bfceb 5 * @note the TSI sensor of FRDM is being touched.
Rhyme 0:0b7a110bfceb 6 * @note By touching the right most side of the sensor
Rhyme 0:0b7a110bfceb 7 * @note program exits the staring loop and pretend to sleep.
Rhyme 0:0b7a110bfceb 8 * @note Then touching the TFT starts the staring loop again.

Rhyme 0:0b7a110bfceb 12 * Note: This program is derived from the SeeeStudioTFTv2 program.
Rhyme 0:0b7a110bfceb 13 * Although both program share same ILI9341 TFT driver,
Rhyme 0:0b7a110bfceb 14 * the touch sensor was not same with the Display I purchased from Akizuki.
Rhyme 0:0b7a110bfceb 15 * http://akizukidenshi.com/catalog/g/gM-07747/
Rhyme 0:0b7a110bfceb 16 * The touch sensor on the display is STMPE610,
Rhyme 0:0b7a110bfceb 17 * so I hacked the minimum spi driver for it (polling mode only).
