Here's a little movie of my first attempt at a graphic lcd program

Any comments/suggestions would be greatly appreciated (I'll u/l the source in a little bit...)

Ohh dear... let me encode that into DiVX...
And a huge THANK YOU to Henry!

As I said, just a first attempt, but I can see some seriously cool uses for this bad boy...

your going to have to use the hardware pixil scroll feature on theat next to make it really smooooooooth

There is a hardware pixel scroll?!?!? *GASP*

What's the command/how would I use it? I've been reading through the documentation and although there is an auto-scroll feature, I'm not exactly sure how to use it...

yes.. it's 0x99 and then the commands.. I'll get those for you... oly the -WBL and the -SM have this. The normal GLK12232-25 does not. That's why it's not documented...

Line scrolling

Code: Select all

{
  unsigned char val;

  ZComm1->WriteCommByte(0xfe);  //prefix
  ZComm1->WriteCommByte(0x99);  //comand
  ZComm1->WriteCommByte(0x02);  //line #2
  ZComm1->WriteCommByte(122);   //how many pixels to scroll

  for (val = 1; val <= 122; val++)
  {
    ZComm1->WriteCommByte(~val);
  }
}

And here is the code for val

Code: Select all

  static unsigned char statval = 0;
  unsigned char val;

  val = statval;

  switch (type)
  {
    case 1:
      ZComm1->WriteCommByte(0xfe);
      ZComm1->WriteCommByte(0x99);
      ZComm1->WriteCommByte(0x00);
      ZComm1->WriteCommByte(0x02);
      ZComm1->WriteCommByte(~statval++);
      ZComm1->WriteCommByte(~statval++);
      break;
    case 2:
      ZComm1->WriteCommByte(0xfe);
      ZComm1->WriteCommByte(0x99);
      ZComm1->WriteCommByte(0x00);
      ZComm1->WriteCommByte(0x01);
      if (val >= :cool:
      {
        ZComm1->WriteCommByte(0xff);
        val -= 8;
      }
      else
      {
        ZComm1->WriteCommByte(Fill[val]);
        val = 0;
      }

      ZComm1->WriteCommByte(0xfe);
      ZComm1->WriteCommByte(0x99);
      ZComm1->WriteCommByte(0x01);
      ZComm1->WriteCommByte(0x01);
      if (val >= :cool:
      {
        ZComm1->WriteCommByte(0xff);
        val -= 8;
      }
      else
      {
        ZComm1->WriteCommByte(Fill[val]);
        val = 0;
      }

      ZComm1->WriteCommByte(0xfe);
      ZComm1->WriteCommByte(0x99);
      ZComm1->WriteCommByte(0x02);
      ZComm1->WriteCommByte(0x01);
      if (val >= :cool:
      {
        ZComm1->WriteCommByte(0xff);
        val -= 8;
      }
      else
      {
        ZComm1->WriteCommByte(Fill[val]);
        val = 0;
      }

      ZComm1->WriteCommByte(0xfe);
      ZComm1->WriteCommByte(0x99);
      ZComm1->WriteCommByte(0x03);
      ZComm1->WriteCommByte(0x01);
      if (val >= :cool:
      {
        ZComm1->WriteCommByte(0xff);
        val -= 8;
      }
      else
      {
        ZComm1->WriteCommByte(Fill[val]);
        val = 0;
      }

      if (statval > 31)
        statval = 0;
      else
        statval++;
      break;
  }
}

Case 2 is timed counter x 2 and Case 3 is Whole screen I balive... it's a chunk of code from one of the test programs...
