/*** LCD Size *****************************************************************
 *      
 *      Used mainly during testing on an 8515/stk500. The 8515 has 512 bytes RAM,
 *      and the frame buffer is 6x84=504 bytes leaving too little (8b) for other
 *      stuff. My solution was to decrease the vertical lines available (temporarily
 *      of course) to let me use 5x84=420 bytes, and have enough for other stuff.
 *
 *      If you are using a processor with less than 1K of RAM, you can decrease the
 *      'fbRows' value to 5. You can draw to the last LCD row without the frame
 *      buffer by calling "lcdXY(x,5)" (where 'x' is 0 to 84) and then writing a
 *      byte by calling "lcdByte(value)" to fill in one column at a time.
 *

        #define fbCols          84

/*** Global Vars **************************************************************

 *      Just the framebuffer and frame buffer cursor
 *      
 **************************************************************************///{
//      uint8 frameBuffer[fbCols][fbRows];      // __attribute__ ((section (".noinit")));
