00021 <span class="comment">/// This display driver performs the basic functions necessary to access</span>
00022 <span class="comment">/// any graphic LCD based on the KS0108 or HD61202 controller chip. For more</span>
00023 <span class="comment">/// advanced functions, use this driver in conjunction with glcd.c.</span>
00024 <span class="comment">/// KS0108/HD61202 displays typically range in size from 64x32 pixels to</span>
00025 <span class="comment">/// 128x128 pixels and up to 3" square. To determine whether a display is</span>
00026 <span class="comment">/// compatible, you should look for the above controller chips to be mounted</span>
00027 <span class="comment">/// on the PC board attached to the display glass. The controller chips are</span>
00028 <span class="comment">/// about 1/2" x 3/4" and have 80+ pins. On larger displays, you may also see</span>
00029 <span class="comment">/// slave LCD driver chips with the numbers KS0107 or HD61203. The display</span>
00030 <span class="comment">/// will likely have an 18 or 20-pin interface. The interface from the LCD</span>
00031 <span class="comment">/// to an AVR processor does not require any additional hardware. If you can</span>
00032 <span class="comment">/// locate a datasheet for your display, that plus the information in the</span>
00033 <span class="comment">/// ks0108conf.h file should be all you need to get hooked up.</span>
