いきさつ
Arduino TFT LCD ScreenというLCD moduleをmbedで使用しました。(module詳細 switch science web)
このLCD moduleのLCD driver ICはST7735 ですが、複数のバージョンがあり、libraryとICのバージョンが合わないと正常に表示しません。
mbedにはこのICに対応したlibrary(ST7735_TFT)がありますが、私が入手したLCD moduleではICの種類が違うためか正常に動作しませんでした。幸い、switch scienceのwebにarduino用の対応libraryがあったので、これを元にmbedのlibrary(ST7735_TFT)に移植しました。
libraryの移植
移植元のArduino library
移植元はswitch science webにある置き換え用TFTライブラリ(Arduino IDE1.0.5用)を使用します。このファイルを解凍してできる、"Adfruit_ST7735.cpp"の230行目以降のGcmd[]配列が該当するdriver ICの設定データになります。

移植先のmbed library
移植先となるmbed libraryはST7735_TFT libraryとなります。この中のST7735_TFT.cppのtft_reset() にIC設定データを追加します。追加したコードを区別するため"ST7735B"というdefine定義で条件コンパイルするようにしました。
追加したコードの最後にある"switch(orientation)"の節はarduinoのlibraryにはなく、mbedのlibraryから修正したものです。

mbed library自体の修正
上記のdriver IC設定値の修正だけでは、LCDの表示領域がずれるなどの不具合がありました。この修正も行います。この不具合の原因が、driver ICの種類の違いよるものなのか、コードそのものの不具合なのかはわかりません。
修正コードは"@ss"のコメントをつけた行になります。
1.driver ICへの画像データバッファアドレス指示の修正
pixel()関数で使用しているwindow()関数の引数が間違っています。元のコードは、終点のx,yが絶対座標形式のようになっていますが、視点からの相対座標を設定しないといけません。
ST7735_TFT.cpp
・ ・ ・ void ST7735_TFT::pixel(int x, int y, int color) { if ((x >= width()) || (y >= height())) return; window(x,y,1,1); //@ss //@ss window(x,y,x+1,y+1); // setup for data ・ ・ ・
2.window()関数の座標原点のずれ
driver ICの仕様かもしれませんが、driver ICの画像データバッファの原点が、x=2, y=1となっています。このlibraryで使用される原点はx=0, y=0なので、offsetを追加します。
ST7735_TFT.cpp
・ ・ ・ void ST7735_TFT::window (unsigned int x, unsigned int y, unsigned int w, unsigned int h) { //@ss なぜか CASET(X軸)で2, RASET(Y軸)で1 が最小値になっており、これがLCDDisplayのx,y原点になっていない(LCDの原点を設定するためには(-2,-1)を指示する必要がある //@ss プログラム上はLCD原点を0,0にするために、この関数でoffsetをかける。 x-=2; //@ss y-=1; //@ss wr_cmd(ST7735_CASET); // column addr set wr_dat(0x00); ・ ・ ・
3.端子定義処理での"orientation"変数の初期値設定タイミングの変更
"ST7735_TFT()"関数内の"orientation"変数の初期値設定がtft_reset()の後になっていますが、tft_reset()内でこの変数を使用しているので、tft_reset()実行前に、変数値を設定する必要があります。
ST7735_TFT.cpp
・ ・ ・ ST7735_TFT::ST7735_TFT(PinName mosi, PinName miso, PinName sclk, PinName cs, PinName rs, PinName reset, const char *name) : _spi(mosi, miso, sclk), _cs(cs), _rs(rs), _reset(reset),GraphicsDisplay(name) { orientation = 1; //@ss tft_reset(); //@ss orientation = 2; char_x = 0; ・ ・ ・
補足:LCD 表示原点の設定
今回使用したmoduleのLCDは160*128ピクセルのものです。画像データの送信によって、x,y軸を入れ替える(横長、縦長)ことができます。これを設定するのが、上記"3"のorientation変数になります。この変数は"set_orientation()"関数の引数として与えることで変更することができます。引数は0,1,2,3となります。
<縦横選択>
0,2 : 縦長(x=0-127, y=0-159)
1,3 : 横長(x=0-159, y=0-127)
<縦(y軸)座標値増加方向>
0,1を基準にした場合、2,3は上下が逆転する
<表示例>
orientation = 0
orientation = 1
orientation =2
orientation=3
