Motoo Tanaka / Mbed 2 deprecated Dentaku Featured

Simple integer calculator using FRDM-KL25Z and Adafruit 2.8" TFT with touch \\ "Dentaku" means "Desktop Calculator" in Japanese \\ On 5-Dec-2015, Support for FRDM-K64F, FRDM-K22F, NUCLEO-F411RE added.

Dependencies:   SPI_STMPE610 UniGraphic mbed vt100

Yet another simple desktop calculator program, only for integer.
As usual I used FRDM-KL25Z, Adafruit 2.8" TFT with touch and UniGraphic library.
Now works with FRDM-K64F, FRDM-K22F, and NUCLEO-F411RE.

整数計算のみの簡単な電卓プログラムです。
例によって、FRDM-KL25Z, Adafruit 2.8" TFT with touch, そして UniGraphic を使用しています。
FRDM-K64F, FRDM-K22F, NUCLEO-F411RE でも動くようになりました。
