I couldn't find that part too, I assumed it's sending the low byte first then high byte,
that's what I did in my attempt. I think it's in Italian.

I only got that zip file. There was no contact infor for the guy, else I would have asked him.

Hi,
I'm making some progress , I manage to display something but it's not as expected.
I'm using 5x8 font only. The text display overlaps, characters are too close to each other or the mapping is incorrect, the graphics is chopped on the bottom. I think it's related to the current_addr_pointer().

Shyam: if you have time, maybe you could look at the attached. I can't figure out where the value 1024 came from, 128x8=1024, but the original author uses 128x128 lcd, mine is 240x128. Also perhaps you could make changes on the struct, it's tedious to add those brackets in the array, I get warnings/errors without them. If you do then wbm() would have to be changed too I think.

this is how test it, same as in the original

CODE:

  do

    {

      i = 0;

      do

        {

          gotoxy(i, i);

          box(239-4*i, 127-4*i);

          refresh_LCD(0);                                               //refresh for each box

          pause(QUARTER_SEC);

        }while (i++ < 16);

      set_display(F5x8, (flag) ? NORMAL : REVERSE);

      flag = !flag;

    }while (flag);

        pause(FIVE_SEC);

        //clearlcd (ALL);

        // test fonts

        set_display(F5x8, NORMAL);

        gotoxy(2,2); wrstr("5/8 FONT");

refresh_LCD(0);

Thanks.

the box routine is working ok, somehow I'm limited to 127x63 size of box. still trying to find which to hack in

the font drawing is still the same.

EDIT: fixed the box, parameters in hline/vline were signed char changed to int16_t, there's still problems
some pixels on the right are not drawn/erased.
EDIT2: now, the box is really fixed

changed in clearfiled()

CODE:

const uint8_t blank[] ={ 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 }; 

to:

CODE:

const uint8_t blank[] = { 0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 };

the font drawing is really tough I need help on that one, but I'm kinda a glad I got this going

Thanks guys, but I freaking did it

my bit rotation was wrong, I just have that cut and paste from post somewhere didn't really know it's inner working, I actually attempted it in assembly, but got lost.
I still don't know where the 1024 value came from tho.

Shyam: Thanks for the time, maybe you should look at this new attachment and see what I'm missing, although it seems to be working I'd like to be able to place bitmap graphic too.

Ajay: I actually just found out about 7zip, it's free why not support it?

I attached a screenshot.
BTW, this is just a home project, I'm just a hobbyist, that's why I'm glad I found this site, with lots of good tutorials and such, not to mention the knowledgeable people that are willing to help. Thank you.
