GLCD and Graphics
PostPosted: Thu Sep 15, 2011 9:36 pm     Reply with quote
Hi everyone,

I need to be able to draw icons on a glcd (KS0108) screen that are 11 x 11 pixels. I can draw icons fine is they are in multiples of 8, but I simply can't get my head around odd sizes.

I have tried the following code found here http://www.ccsinfo.com/forum/viewtopic.php?t=20912&highlight=bitmap

Code:

void glcd_sprite(int8 col, lig , x , y , int16 adresse)
{
   int8  *p;
   int8 i, j, data;
   int16 temp;


   for(i=0; i<lig; ++i)
   {
      temp =  y + i;
      temp *= 64;
      temp += x;
      for(j=0; j<col; ++j)
      {
         p = temp + j;
         if(x + j > 63)
         {
           p += displayData.right - 64;
         }
         else
         {
           p += displayData.left;
         }
         *p = image[i++];
      }

   }
}



Problem with that code is it will not allow me to position the image where ever I want on the y axis.

I guess my question is, has anyone got a function to display oddball image sized images on a GLCD??

Thanks

Mark

You may be able to run the graphic through fontgen to reorganize the data.
