We can't communicate :D :D :D :D

I need a function that draw to the LCD the bytes. The function you post here, only converts pixels into hexadecimal values. I need the function that draw this pixels (in hexadecimal).

Thanks

Ok, here's one piece of code that writes a bitmap to T6963C. I have translated this from some delphi code last spring so this isn't my work.

Code:
void cT6963C::ShowBMP(Graphics::TBitmap *pBitmap)
{
  int x=0,y=0,z;
  int i;
  int addr;
  float pp;
  TColor p;

  Randomize();

  addr = G_BASE + (y*BYTES_PER_ROW_GFX) + (x/font_width);

  T6963C.WriteData(addr & 0xFF);
  T6963C.WriteData(addr >> 8);
  T6963C.WriteCtrl(0x24);
  for (y=0;y<ypixels;y++)
    for (x=0;x<xpixels/font_width;x++)
    {
      i=0;
      for(z=0;z<font_width;z++)
      {
        p=pBitmap->Canvas->Pixels[x*font_width+z][y];
        pp=0.6*(p & 0xFF)+0.30*((p >> 8) & 0xFF)+0.1*((p >> 16) & 0xFF);
        i=i << 1;
        if (pp<=random(255))
           i=i | 1;
      }
      T6963C.WriteData(i);
      T6963C.WriteCtrl(0xC0);
    }
}
