Vision sensor setup

and here is how to set a color code using two signatures.

pretty much the same code used.

int main() {        
    // Draw an area representing the vision sensor field of view
    Brain.Screen.clearScreen( vex::color::black );
    Brain.Screen.setPenColor( vex::color::green );
    Brain.Screen.drawRectangle( screen_origin_x-1, screen_origin_y-1, screen_width+2, screen_height+2 );

    while(1) {
      // request any objects with color code C1
      int numberObjects = Vision1.takeSnapshot( C1 );
      
      Brain.Screen.setPenColor( vex::color::white );
      Brain.Screen.setFont( mono20 );
      Brain.Screen.setCursor( 2, 2 );
      Brain.Screen.print( "CC 1 %2d", (int)numberObjects );

      // draw any objects found
      drawObjects( Vision1, vex::color::green, true );

      // run 10 times/second
      this_thread::sleep_for(100);      
    }   
}

and a screen grab
