Simple test program for FRDM-KL25Z and Adafruit 2.8" TFT display. For the touch sensor, only polling mode is implemented.
Dependencies: MMA8451Q SPI_STMPE610 TSI UniGraphic mbed
This program was to test Adafruit 2.8" TFT with touch with FRDM-KL25Z.
After download the binary to the FRDM-KL25Z and push the reset button ,
a simple welcome message will be displayed.
このプログラムは私が秋月で購入した Adafruit 2.8" TFT
http://akizukidenshi.com/catalog/g/gM-07747/
をFRDM-KL25Z で試すために書いたものです。
ダウンロード後にFRDM-KL25Zのリセットスイッチを押すと
最初の画面が表示されます。
Now using UniGraphic library.
And the problem of remaining previous screen is gone. ;-)
For a little bonus, TS_Eyes and Maze are also included.
UniGraphic ライブラリ版になり、画面にごみが残るバグが治りました。
おまけに TS_Eyes と Maze も追加してあります。 (^ ^)v
If you push and keep the right side of the screen,
the screen will advance to the page2, which is a simple graph sample.
ここで画面の右側をしばらく押していると、次のページに移行します。
このページでは、簡単なグラフを表示する例を描画しています。
And if you do the same again, the program advances to the page3,
which is a data display page of MMA8451Q accelerometer mounted on
the FRDM-KL25Z.
さらに画面の右側をしばらく押していると、次のページに移行します。
ここでは、FRDM-KL25Zに搭載されている MMA8451Q という３軸の
加速度センサの値を表示しています。
And this is the last page of this program, so far, so if you
try to advance page, it will return to the first page.
このページが最後のページになっているので、さらにページ送りをすると
最初のページに戻ります。
