Need some newbie help please

[MrMagoo Profile]

Ok that got rid of those errors, but now I get this one

** L2310 (E) Undefined external symbol "_AddIn_main" referenced in "E:\Casio\OS\FX\lib\setup.obj"

[SimonLothar]

** L2310 (E) Undefined external symbol "_AddIn_main" referenced in "E:\Casio\OS\FX\lib\setup.obj"

This error occurs, when the source file, which contains AddIn_main is not included in the SDK's source file list.

Got it!
All working as expected now.
When we initialise a double variable, can it be a blank value?
The prompts are printing the inital value, which shows up as 0.0000000 and we have to delete that string before we can input the new one.

[SimonLothar]

When we initialise a double variable, can it be a blank value?

That would be NaN (Not a Number). Alas, I could not find NaN within the CASIO SDK (f. i. in limits.h, where it should be).
Hence add...

Code: Select all

// IEEE 754 double quiet NaN
static unsigned char cqNAN[ 8 ] = { 0x7F, 0xF8, 0, 0, 0, 0, 0, 0 };      // qNaN

//
double qNaN( void ){
   return *(double*)cqNAN;
};

//
int is_qNaN( double d ){
   return !memcmp( &d, cqNAN, sizeof( cqNAN ) );
}


to input.cpp.

In input.cpp change

Code: Select all

   memset( buffer, 0, sizeof( buffer ) );   
   sprintf( (char*)buffer, "%f", d );


to

Code: Select all

   memset( buffer, 0, sizeof( buffer ) );   
   if ( !is_qNaN( d ) ) sprintf( (char*)buffer, "%f", d );


Add this

Code: Select all

double qNaN( void );
int is_qNaN( double d );


to input.hpp.

In Addin_main initialize d

Code: Select all

   d = qNaN();


BTW: of course you can isolate the NaN-thing in a separate source module.

Done all that, got this error :-/

C5020 (E) Identifier "is_qNaN" is undefined

[SimonLothar]

I think you added the definition of is_qNaN(...) at the end of input.cpp, after its first use.
The definition of is_qNaN(...) must either precede its first use inside of input.cpp or you'd have to declare the interface of is_qNaN(...) at the beginning of input.cpp.

Code: Select all

// IEEE 754 double
static unsigned char cqNAN[ 8 ] = { 0x7F, 0xF8, 0, 0, 0, 0, 0, 0 };      // qNaN

//
double qNaN( void ){
   return *(double*)cqNAN;
};

//
int is_qNaN( double d ){
   return !memcmp( &d, cqNAN, sizeof( cqNAN ) );
}

//
int InputDouble( int x, int y, unsigned char*prompt, double&d ){
unsigned char buffer[20];
int editresult;
   memset( buffer, 0, sizeof( buffer ) );   
   if ( !is_qNaN( d ) ) sprintf( (char*)buffer, "%f", d );

Now the graphical menu, you need:

Define the bitmaps:

where do I define the bitmaps?

[SimonLothar]

where do I define the bitmaps?

I use ms-paint to create the 32x18 b/w-bmp file (the width has to be a multiple of 8).
Hint: the last two colums of the bitmap are ignored with this example, t. i. graphicMenu uses only a width of 30 pixels per icon.
Then I use my fileconverter to transfer the bmp-file to C-source.

EDIT: I misunderstood your question. I defined the bitmaps in the main-module (before iconlist is used). You could put the code in a separate file and include it.

[MrMagoo Profile]

Hi Simon,

I got this error

L2300 (E) Duplicate symbol "_iconlist" in "E:\Casio\Projects\Inputs\Debug\Bitmaps.obj"

I have the bitmap defs in a cpp file, which is included. #include "bitmaps.cpp"
