カラーセンサー情報取得６
カラーセンサーが２チャネル分あるとき、緑色だけの
情報を取得することもできます。
緑色の場合、情報は２種しかないので、どちらかを基準と
してバーの長さを決定します。
２チャネルの情報をga、gbとすると、次の場合分けで
バーの長さを調整します。
- ga < gb → gbを基準に、その何％がgaかを求める
- ga = gb → 同じ固定長とする
- ga > gb → gaを基準に、その何％がgbかを求める
バー表示を、フラグgflagの論理値で制御します。
対応するdraw中のブロックを見ると、以下。
/* draw bars */
int rate_rgbi ;
rate_rgbi = max(max(rxa,gxa),max(bxa,ixa));
if ( rate_rgbi > 0 ) { show_bars(rxa,gxa,bxa,ixa,0); }
rate_rgbi = max(max(rxb,gxb),max(bxb,ixb));
if ( rate_rgbi > 0 ) { show_bars(rxb,gxb,bxb,ixb,1); }
フラグgflagの判定処理を加えます。
/* draw bars */
int rate_rgbi ;
if ( gflag == true ) {
int rra,rrb ;
/* default */
rra = 100 ; rrb = 100 ;
/* compare */
if ( gxa == gxb ) {
rra = 50 ; rrb = 50 ;
} else {
if ( gxa < xgb ) {
rra = (int)(gxa * 100.0) / xgb);
} else {
rrb = (int)(gxb * 100.0) / xga);
}
}
/* draw */
fill( 0,255, 0); rect(100,70+27,rra,20);
fill( 0,255, 0); rect(290,70+27,rrb,20);
} else {
rate_rgbi = max(max(rxa,gxa),max(bxa,ixa));
if ( rate_rgbi > 0 ) { show_bars(rxa,gxa,bxa,ixa,0); }
rate_rgbi = max(max(rxb,gxb),max(bxb,ixb));
if ( rate_rgbi > 0 ) { show_bars(rxb,gxb,bxb,ixb,1); }
}
緑色だけのバーを表示する部分を、ひとつの関数に
まとめてわかりやすくします。
void show_green_bars(int x,int y)
{
int rra,rrb ;
/* default */
rra = 100 ; rrb = 100 ;
/* compare */
if ( x == y ) {
rra = 50 ; rrb = 50 ;
} else {
if ( x < y ) {
rra = (int)(x * 100.0 / y);
} else {
rrb = (int)(y * 100.0 / x);
}
}
/* draw */
fill( 0,255, 0); rect(100,70+27,rra,20);
fill( 0,255, 0); rect(290,70+27,rrb,20);
}
バー表示部分は、簡単になります。
int rate_rgbi ;
if ( gflag == true ) {
show_green_bars(gxa,gxb);
} else {
rate_rgbi = max(max(rxa,gxa),max(bxa,ixa));
if ( rate_rgbi > 0 ) { show_bars(rxa,gxa,bxa,ixa,0); }
rate_rgbi = max(max(rxb,gxb),max(bxb,ixb));
if ( rate_rgbi > 0 ) { show_bars(rxb,gxb,bxb,ixb,1); }
}
