Masato YAMANISHI / Mbed 2 deprecated SPI18TFT_FRDM-KL25Z

for Aitendo TFT LCD (M018C7735SPI)

Dependencies:   mbed

original http://mbed.org/users/smultron1977/code/SPI18TFT/

I'd changed for Aitendo TFT LCD(M018C7735SPI). see http://mbed.org/users/masato/notebook/aitendo-graphic-lcd-m018c7735spi/

http://mbed.org/users/smultron1977/code/SPI18TFT/ を使って Aitendo の TFT-LCD (M018C7735SPI)を動かしてみると、ちょっと不具合があったので適当にいじってみました。ついでに FRDM-KL25Z 用に 8bit SPI のみにしたのがこれ。テキストが切れることがあって原因を調べたところ、printf などが 通常の PC と同じく、非同期動作するためでした。必要に応じて flush すれば良いです。こちらのページに動作中の写真とかあります。http://mbed.org/users/masato/notebook/aitendo-graphic-lcd-m018c7735spi/
