  1. 3D加速器與RTC

  2. 範例程式 • 由網站下載LCM-RTC-mma.rar • 編譯執行

  3. 實驗 • 轉動發展板 • 觀查X,Y,Z值與位置的關係

  4. 水平靜止狀態 Z X G

  5. 斜置靜止狀態 Z=G * cos 傾斜角度 X=G * sin G

  6. lcm_disp_int_10(2, Coordinates[1]); • lcm_disp_int_10(3, Coordinates[2]); • lcm_disp_int_10(4, Coordinates[0]);

  7. x = x + (Coordinates[1] - x_base)/KFACTOR; //x • y = y + (Coordinates[2] - y_base)/KFACTOR; //y • z = z + (Coordinates[0] - z_base)/KFACTOR; //z

  8. // calibrate • for(g=0; g<64; g++) { • GetCoordinates(); • } • x_base = Coordinates[1]; • z_base = Coordinates[0]; • y_base = Coordinates[2];

  9. while(1) { • // unsigned int i; • // mma and ball ------------------------------------------------------------ • GetCoordinates(); • // with calibrate when start • x = x + (Coordinates[1] - x_base)/KFACTOR; //x • y = y + (Coordinates[2] - y_base)/KFACTOR; //y • z = z + (Coordinates[0] - z_base)/KFACTOR; //z • // unsigned int i; • char min=0, hour=0; • if (sec >= 60 ) • {sec=0; • min=min+1;

  10. void main( void ) • { • char min=0, hour=0; • // variables • // r - row variable, c - column variable • char x=128, y=128, z=128; • // g - temp variable • char g;
