Motoo Tanaka / Mbed 2 deprecated TS_Eyes Featured

TS Eyes A simple program to test TSI function of FRDM-KL25Z board using the Adafruit 2.8" TFT with Touch Sensor. It behaves like the X11eyes, but this time it follows the point where the TSI sensor is being touched. When the right most edge of the TSI is touched, the program exits the loop and pretend to be sleeping. By touching TFT display, program resume to the staring eye loop.

TS Eyes Just like the good old X11eyes, this program follows the point where the TSI sensor of FRDM is being touched.

When downloaded and reset, the eyes see the left side as the TSI read value is 0.

The eyes follow where you touch on the TSI sensor of FRDM board.　

TSIセンサを触るとその方向に瞳が動きます。

When the right most side of the sensor is touched, the program exits the following loop and pretend to be sleeping.

指が一番右端にかかりますと、ループを抜けてお休みモードに入ります。 TFTの表面をタップすることで、起こすことができます。

 /* 
  * 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).
