Rhyme 0:cd5e3d371b54 16 * the touch sensor was not same with the Display I purchased from Akizuki.
Rhyme 0:cd5e3d371b54 17 * http://akizukidenshi.com/catalog/g/gM-07747/
Rhyme 0:cd5e3d371b54 18 * The touch sensor on the display is STMPE610,
Rhyme 0:cd5e3d371b54 19 * so I hacked the minimum spi driver for it (polling mode only).
