Need some newbie help please

Did you include bitmaps.cpp in the project's file list? Then try to delete the include-statement. Or delete bitmaps.cpp from the project's file list. Highlander - There can be only one!

Ok, got rid of that error, but now getting this one.

E:\Casio\Projects\Inputs\Main.cpp(21) : C5020 (E) Identifier "iconlist" is undefined
E:\Casio\Projects\Inputs\Main.cpp(17) : C5550 (W) Variable "editresult" was set but never used

E:\Casio\Projects\Inputs\Main.cpp(21) : C5020 (E) Identifier "iconlist" is undefined

Remove bitmaps.cpp from the project's file list, rename it to bitmaps.hpp and include it at the beginning of the main-file, t. i. before Addin_main.

E:\Casio\Projects\Inputs\Main.cpp(17) : C5550 (W) Variable "editresult" was set but never used

This is only a warning. If you assign a value to a variable and you do not use this variable, the C++ compiler assumes, that you forgot something and hence warns you.

Love it!

I have created my own bitmaps too!

Two more questions, how do i set the menu grid size? so maybe 4x3?
how do I process the result of the item selected? I tried printing editresult, but it was the wrong variable type, and I tried using;

Code: Select all

sprintf( (char*)out_buffer, "%f", editresult );   // convert the processing result back to a presentable string


but just got zero

Love it!

That lightens my heart.

At present this is fixed and cannot be parameterized. I intended to do some enhanced version of graphicMenu with variable icon sizes this weekend...provided the weather does not redirect me to some beer garden.

We cannot blame the compiler for that. "%f" is for doubles. editresult is int. int needs "%d" as formatstring.
Best refer to page 358..363 of "SHC Manual.PDF". There all secrets become reveiled.

Ha Ha Ha, I dont blame you.
Would a work-around be to restrict the movement? So only the first 12 are accessible?

[MrMagoo Profile]

Yes! you can. I changed the 4 to 3 in the up and down getkey cases.

Boom! It's done

change

Code: Select all

const unsigned char* iconlist[] = { ICON1, ICON2, ICON3, ICON4,
                           ICON5, ICON1, ICON2, ICON3,
                           ICON4, ICON5, ICON1, ICON2,

Ok this is awesome, got it working perfectly

Next question, how do I display a bitmap in a given position, at a given size?
Does the width of the bmp file still have to be a multiple of 8?

Also, in my old casio basic programs I used the matrix to store and retrieve data, can this be done with SDK? or can I store data someehere more secure?

Thanks!

fine

...how do I display a bitmap in a given position, at a given size?

In the definition of a bitmap the width has always to be a multiple of 8.

Code: Select all

const unsigned char ICON1[]={
0xFF,0xFF,0xFF,0xFC,
0x80,0,0,0x04,
0x80,0,0,0x04,
...
0 };

But the displaying function Bdisp_WriteGraph_VRAM clips unneeded bits, if you pass a smaller width or height:

Code: Select all

DISPGRAPH dg;

  dg.x = 10;  // 0..127
  dg.y = 20;  // 0..63
  dg.GraphData.width = 30;
  dg.GraphData.height = 18;
  dg.GraphData.pBitmap = (unsigned char*)ICON1;
  dg.WriteModify = IMB_WRITEMODIFY_NORMAL;
  Bdisp_WriteGraph_VRAM( &dg );

Also, in my old casio basic programs I used the matrix to store and retrieve data, can this be done with SDK? or can I store data someehere more secure?

It is possible to access a built-in matrix from out of an add-in.
But as you said, it would not be secure, because the built-in matrix could be changed by the built-in MAIN MENU functions, as well.

To save data from out of an add-in, there are two basic options.

You could use the main memory:
Advantage: fast, no optimization necessary.
Disadvantage: limited space; looses all changes since the last proper "switch off", if the calculator is not shut down properly, f. i. by a reset. Take care: some games do a reset indeed!

You could use the storage memory:
Advantage: a lot of space (if it isn't crammed with games); data are immediately saved.
Disadvantage: if used heavily with deleting, creating and writing, some day optimization will be necessary.

If you need a real big dump (up to 2 GB), a SD card would be an option with some models. But it is rather slow.
