Casio USB Power Graphic 2 : Add-in Compatibility List

2012-09-20T19:46:31Z

Helder7:

The new casio Fx9860 with label ''USB Power Graphic 2'', now support sdhc cards up to 32gb and use an SH-4A CPU without FPU (SH-7305) like on the Prizm.x

However, programs/games compatibility is compromised, with changes in [http://www.casiopeia.net/forum/viewtopic.php?f=20&t=1421 some sdk functions] and [http://www.casiopeia.net/forum/viewtopic.php?p=12607#p12607 port addresses]. According to the reports of some users maybe more than 70% of the add-in games/programs do not work in the new model.

On the left of the image is the new model USB Power Graphic 2, on the right is the old model.

Helder7: /* Set up multiple strong back */

{{MsgBox|title=Hello !|text=New version ('''1.2''') released! If you are using an older version [http://www.casio-scene.com/downloads.php?do=file&id=396 update now]! This page will be improved in next days.|TitleStyle=color:#00FF44;text-decoration:underline;}}
 
==Getting Started==
Copy the two files inside the bin folder (WSC.g1a, FVM.g1a) to the calculator.
In order to edit the source code on calc, you may need to use the [http://www.casio-scene.com/downloads.php?do=file&id=119 EDITv1.51], of course, you can also edit the source code on the computer, it is plain text.

After the installation is complete, the main menu should be as follows:

[[File:Wsc-fvm-installed.jpg]]

===Making a hello world===
Open the EDIT, the storage Mem (Warning: Do not use the Main Mem) and create a new document.

[[File:Wsc-fvm-hello-c.jpg]]

Enter the text:
<pre>void main( )
{
printf( “Hello World!\n” );
}</pre>

(P.S. EDIT could adjust the font size（shift--set up to enter the setting interface）, you can see more code on a screen by using the small font, it is recommended to use the small print,the recommended settings below)

[[File:Edit-settings.png]]

The input is completed as follows:

[[File:Wsc-fvm-hello-c-code.jpg]]

To compile the file, exit, enter the WSC, press the F1 (compile) to compile the source code.

[[File:Wsc-fvm-compile-file.jpg]]

If there are no errors, the screen will output “Done”, if there are some errors, you can go back to EDIT to modify. After compiling, enter FVM, press F1(run) to run the bytecode file. the screen will output “hello world”

[[File:Wsc-fvm-hello-f.jpg]][[File:Wsc-fvm-run-hello.jpg]]

==WSC Support the C language features==
===The operator===

+ - * / % += -= *= /= < <= > >= == != && || ! != &

note the last ‘&’ is geting address but not bitwise and

===Data type===

int char float mult-dimensions array pointer(can’t point to array) string constant

===Statement===

if else while for return break

===Notes===

C style /*............*/ and C++ style //............

===The function===

supports recursion, a detailed list of library functions, see [[#WSC_Functions|library section]]

===Preprocessor===

Simple macro replacement (with parameters) a #define, #include (not a real file contains internal use only)

==WSC Error reporting==
The error reporting of WSC is not perfect,

WSC will displayed the error message when the error is detected, as below:

[[File:Wsc-error-reporting.jpg]]

You can press menu key to exit and go back to modify source code. If you press any other key, the next error message will be displayed.

Note that WSC did not prompt a warning!

Any pointers, arrays are the same in its eyes,

Any assignment between int, char, float will not generate any errors.

A function that return type is not ‘void’ don’t return a value will not generate any errors.

==Some differences in the WSC with the standard C==
There ary some differences between the WSC and the standard C.

===Doesn’t require the function declaration===

As long as the function is defined in the file, regardless of location, you can call anywhere.

===Only two scopes===

The program has only two scopes, global scope and local scope of funcion.

<pre>void main()
{
int a;
{
int a;
}
}</pre>

the example program will recerve an error message “Variable ‘a’ redefinition”

===int * a, b；===
a and b will both be a pointer.(so, it recommended that written int* a, b; but not int *a, b;);

===int *p； p++；===
The actual value of p will add 4(i.e. sizeof(int) ) in the ANSI C, but WSC will only let p add 1

===char s[50] = “asdfjkl”；===
This initialization is not yet supported, sample sentence is wrong.

===int a[2][2] = { 1, 2, 3, 4 }；===
This initialization is not yet supported, sample sentence is wrong.

Mult-idimensional array initialization must be grouped properly, such as

int a[2][2] = { {1, 2}, {3, 4} };

the follow is alse correct:

int a[2][2] = { {1}, {3} };

==Notice & Tips==

===int a[10]；printf( “%d”, a )；===
The programmer’s intent is to get the value of a. But as mentioned above, all the pointer are the same in WSC, WSC see a as a pointer to char. so some errors occur.

a correct way as follw:

int a[10]; int t = a; printf( “%d”, t );

===char ch；scanf( “%c”, &ch )；===
For some reasons, the statement is wrong, it is recommended to use getchar();

===Enter the uppercase letters===
Press F6 in the input interface, than you can enter the uppercase letters

===FVM will automatically initialize the random number seed===
Don’t require the programmer calling srand();

===Enter the uppercase letters===

Press F6 in the input interface switch case

===Set up multiple strong back===

<pre>#progma FORCE_BREAK</pre>

add the statement above in the source code, then you can hold down F1 + F2 + F6 to force quit the running program.

==List of library functions==
Has now completed most of 9860 to support the c standard functions, the next version will be added to the SDK functions.

printf, sprintf, scanf, sscanf is the overloaded function. Note that they do not have a variable argument list

===File name format===
A few examples to illustrate the format of the file name:
File named 2.txt in the Storage Mem in the root directory is "\\\\fls0\\2.txt"
File named 2.txt in the directory book in the Storage Mem is "\\\\fls0\\book\\2.txt"
File named 2.txt in the root directory of the SD card is "\\\\crd0\\2.txt"
Directory book in SD card is “\\\\crd0\\book”

In this moment you can’t operate the file in Main Mem

Note that the filename is case sensitive!

\exemple\FILE.c shows how to operate file

WSC and FVM

2012-07-07T18:20:34Z

Helder7: /* Enter the uppercase letters */

{{MsgBox|title=Hello !|text=New version ('''1.2''') released! If you are using an older version [http://www.casio-scene.com/downloads.php?do=file&id=396 update now]! This page will be improved in next days.|TitleStyle=color:#00FF44;text-decoration:underline;}}
 
==Getting Started==
Copy the two files inside the bin folder (WSC.g1a, FVM.g1a) to the calculator.
In order to edit the source code on calc, you may need to use the [http://www.casio-scene.com/downloads.php?do=file&id=119 EDITv1.51], of course, you can also edit the source code on the computer, it is plain text.

After the installation is complete, the main menu should be as follows:

[[File:Wsc-fvm-installed.jpg]]

===Making a hello world===
Open the EDIT, the storage Mem (Warning: Do not use the Main Mem) and create a new document.

[[File:Wsc-fvm-hello-c.jpg]]

Enter the text:
<pre>void main( )
{
printf( “Hello World!\n” );
}</pre>

(P.S. EDIT could adjust the font size（shift--set up to enter the setting interface）, you can see more code on a screen by using the small font, it is recommended to use the small print,the recommended settings below)

[[File:Edit-settings.png]]

The input is completed as follows:

[[File:Wsc-fvm-hello-c-code.jpg]]

To compile the file, exit, enter the WSC, press the F1 (compile) to compile the source code.

[[File:Wsc-fvm-compile-file.jpg]]

If there are no errors, the screen will output “Done”, if there are some errors, you can go back to EDIT to modify. After compiling, enter FVM, press F1(run) to run the bytecode file. the screen will output “hello world”

[[File:Wsc-fvm-hello-f.jpg]][[File:Wsc-fvm-run-hello.jpg]]

==WSC Support the C language features==
===The operator===

+ - * / % += -= *= /= < <= > >= == != && || ! != &

note the last ‘&’ is geting address but not bitwise and

===Data type===

int char float mult-dimensions array pointer(can’t point to array) string constant

===Statement===

if else while for return break

===Notes===

C style /*............*/ and C++ style //............

===The function===

supports recursion, a detailed list of library functions, see [[#WSC_Functions|library section]]

===Preprocessor===

Simple macro replacement (with parameters) a #define, #include (not a real file contains internal use only)

==WSC Error reporting==
The error reporting of WSC is not perfect,

WSC will displayed the error message when the error is detected, as below:

[[File:Wsc-error-reporting.jpg]]

You can press menu key to exit and go back to modify source code. If you press any other key, the next error message will be displayed.

Note that WSC did not prompt a warning!

Any pointers, arrays are the same in its eyes,

Any assignment between int, char, float will not generate any errors.

A function that return type is not ‘void’ don’t return a value will not generate any errors.

==Some differences in the WSC with the standard C==
There ary some differences between the WSC and the standard C.

===Doesn’t require the function declaration===

As long as the function is defined in the file, regardless of location, you can call anywhere.

===Only two scopes===

The program has only two scopes, global scope and local scope of funcion.

<pre>void main()
{
int a;
{
int a;
}
}</pre>

the example program will recerve an error message “Variable ‘a’ redefinition”

===int * a, b；===
a and b will both be a pointer.(so, it recommended that written int* a, b; but not int *a, b;);

===int *p； p++；===
The actual value of p will add 4(i.e. sizeof(int) ) in the ANSI C, but WSC will only let p add 1

===char s[50] = “asdfjkl”；===
This initialization is not yet supported, sample sentence is wrong.

===int a[2][2] = { 1, 2, 3, 4 }；===
This initialization is not yet supported, sample sentence is wrong.

Mult-idimensional array initialization must be grouped properly, such as

int a[2][2] = { {1, 2}, {3, 4} };

the follow is alse correct:

int a[2][2] = { {1}, {3} };

==Notice & Tips==

===int a[10]；printf( “%d”, a )；===
The programmer’s intent is to get the value of a. But as mentioned above, all the pointer are the same in WSC, WSC see a as a pointer to char. so some errors occur.

a correct way as follw:

int a[10]; int t = a; printf( “%d”, t );

===char ch；scanf( “%c”, &ch )；===
For some reasons, the statement is wrong, it is recommended to use getchar();

===Enter the uppercase letters===
Press F6 in the input interface, than you can enter the uppercase letters

===FVM will automatically initialize the random number seed===
Don’t require the programmer calling srand();

===Enter the uppercase letters===

Press F6 in the input interface switch case

===Set up multiple strong back===

<pre>#progma FORCE_BREAK</pre>

Anywhere in the source code to add the above statement, you can hold down the F1 + F2 + F6 to force quit the program execution.

==List of library functions==
Has now completed most of 9860 to support the c standard functions, the next version will be added to the SDK functions.

printf, sprintf, scanf, sscanf is the overloaded function. Note that they do not have a variable argument list

WSC and FVM

2012-07-07T18:20:11Z

Helder7: /* FVM will automatically initialize the random number seed */

{{MsgBox|title=Hello !|text=New version ('''1.2''') released! If you are using an older version [http://www.casio-scene.com/downloads.php?do=file&id=396 update now]! This page will be improved in next days.|TitleStyle=color:#00FF44;text-decoration:underline;}}
 
==Getting Started==
Copy the two files inside the bin folder (WSC.g1a, FVM.g1a) to the calculator.
In order to edit the source code on calc, you may need to use the [http://www.casio-scene.com/downloads.php?do=file&id=119 EDITv1.51], of course, you can also edit the source code on the computer, it is plain text.

After the installation is complete, the main menu should be as follows:

[[File:Wsc-fvm-installed.jpg]]

===Making a hello world===
Open the EDIT, the storage Mem (Warning: Do not use the Main Mem) and create a new document.

[[File:Wsc-fvm-hello-c.jpg]]

Enter the text:
<pre>void main( )
{
printf( “Hello World!\n” );
}</pre>

(P.S. EDIT could adjust the font size（shift--set up to enter the setting interface）, you can see more code on a screen by using the small font, it is recommended to use the small print,the recommended settings below)

[[File:Edit-settings.png]]

The input is completed as follows:

[[File:Wsc-fvm-hello-c-code.jpg]]

To compile the file, exit, enter the WSC, press the F1 (compile) to compile the source code.

[[File:Wsc-fvm-compile-file.jpg]]

If there are no errors, the screen will output “Done”, if there are some errors, you can go back to EDIT to modify. After compiling, enter FVM, press F1(run) to run the bytecode file. the screen will output “hello world”

[[File:Wsc-fvm-hello-f.jpg]][[File:Wsc-fvm-run-hello.jpg]]

==WSC Support the C language features==
===The operator===

+ - * / % += -= *= /= < <= > >= == != && || ! != &

note the last ‘&’ is geting address but not bitwise and

===Data type===

int char float mult-dimensions array pointer(can’t point to array) string constant

===Statement===

if else while for return break

===Notes===

C style /*............*/ and C++ style //............

===The function===

supports recursion, a detailed list of library functions, see [[#WSC_Functions|library section]]

===Preprocessor===

Simple macro replacement (with parameters) a #define, #include (not a real file contains internal use only)

==WSC Error reporting==
The error reporting of WSC is not perfect,

WSC will displayed the error message when the error is detected, as below:

[[File:Wsc-error-reporting.jpg]]

You can press menu key to exit and go back to modify source code. If you press any other key, the next error message will be displayed.

Note that WSC did not prompt a warning!

Any pointers, arrays are the same in its eyes,

Any assignment between int, char, float will not generate any errors.

A function that return type is not ‘void’ don’t return a value will not generate any errors.

==Some differences in the WSC with the standard C==
There ary some differences between the WSC and the standard C.

===Doesn’t require the function declaration===

As long as the function is defined in the file, regardless of location, you can call anywhere.

===Only two scopes===

The program has only two scopes, global scope and local scope of funcion.

<pre>void main()
{
int a;
{
int a;
}
}</pre>

the example program will recerve an error message “Variable ‘a’ redefinition”

===int * a, b；===
a and b will both be a pointer.(so, it recommended that written int* a, b; but not int *a, b;);

===int *p； p++；===
The actual value of p will add 4(i.e. sizeof(int) ) in the ANSI C, but WSC will only let p add 1

===char s[50] = “asdfjkl”；===
This initialization is not yet supported, sample sentence is wrong.

===int a[2][2] = { 1, 2, 3, 4 }；===
This initialization is not yet supported, sample sentence is wrong.

Mult-idimensional array initialization must be grouped properly, such as

int a[2][2] = { {1, 2}, {3, 4} };

the follow is alse correct:

int a[2][2] = { {1}, {3} };

==Notice & Tips==

===int a[10]；printf( “%d”, a )；===
The programmer’s intent is to get the value of a. But as mentioned above, all the pointer are the same in WSC, WSC see a as a pointer to char. so some errors occur.

a correct way as follw:

int a[10]; int t = a; printf( “%d”, t );

===char ch；scanf( “%c”, &ch )；===
For some reasons, the statement is wrong, it is recommended to use getchar();

===Enter the uppercase letters===
Press F6 in the input interface switch case.

===FVM will automatically initialize the random number seed===
Don’t require the programmer calling srand();

===Enter the uppercase letters===

Press F6 in the input interface switch case

===Set up multiple strong back===

<pre>#progma FORCE_BREAK</pre>

Anywhere in the source code to add the above statement, you can hold down the F1 + F2 + F6 to force quit the program execution.

==List of library functions==
Has now completed most of 9860 to support the c standard functions, the next version will be added to the SDK functions.

printf, sprintf, scanf, sscanf is the overloaded function. Note that they do not have a variable argument list

size is the bytes to be read from the file. 
readpos is the starting position to read. If the readpos parameter is -1, this functi on reads data from the position last read ended. If the readpos parameter greater than or equal to 0, this function reads data from the position indicated by the readpos parameter. 
If the function succeeds, this function returns the number of bytes actually read. It is greater than or equal to 0. 
If the function fails, the return value is an error code. It is a negative value.

====int writefile( int handle, void *buf, int size )====
handle is the return value of openfile() 
If the function succeeds, this function returns the number of bytes actually read. It is greater than or equal to 0. 
If the function fails, the return value is an error code. It is a negative value.

====int seekfile( int handle, int pos )====
moves the file pointer of an open file 
If the function succeeds, this function returns the number of bytes that can continuously be read. It is greater than or equal to 0. 
If the function fails, the return value is an error code. It is a negative value.

====int closefile( int handle )====
closes an open file handle

====int getfree( int type, int *freebytes )====
retrieves the size of the free space, in bytes, of the specified device 
The following definitions are declared for type.

<table width="300" border="1">
<tr>
<td>MAIN_FREE</td>
<td>main memory</td>
</tr>
<tr>
<td>STO_FREE</td>
<td>storage memory</td>
</tr>
<tr>
<td>SD_FREE</td>
<td>sd card</td>
</tr>
</table>
( getfree( SD_FREE, &size ); )

freebytes is the pointer to the size of the free space 
If the function succeeds, this function returns 0. 
If the function fails, the return value is an error code. It is a negative value.

====int getsize( int handle )====
retrieves the size, in bytes, of the specified file.

====int createfile( const char *name, int size )====
Creates a file ([[#File_name_format|View File Name Format]]) 
If the function succeeds, the return value is 0. 
If the function fails, the return value is an error code. It is a negative value.

====int createdir( const char *name )====
Creates a directory ([[#File_name_format|View File Name Format]]) 
If the function succeeds, the return value is 0. 
If the function fails, the return value is an error code. It is a negative value.

====int deletefile( const char *name )====
Delete a file ([[#File_name_format|View File Name Format]]) 
If the function succeeds, the return value is 0. 
If the function fails, the return value is an error code. It is a negative value.

====int deletedir( const char *name )====
Delete a directory ([[#File_name_format|View File Name Format]]) 
If the function succeeds, the return value is 0. 
If the function fails, the return value is an error code. It is a negative value.

====int getkey( int *keycode )====
Performs a key wait and returns a value indicating the pressed key

If there are no characters in the key buffer, this func tion waits until a character arrives and then returns immediately. 
Even if the menu key pressed, this function does not return menu key code. The system processes the menu key event. 
Off event, Auto Power Off event, and contrast adjustment are also handled by this function. If an off or Auto Power Off event occurs the application will not be notified. Once the calculator is turned back on control is returned to the GetKey function.

If a character key was pressed, the return value is 1. 
If a control key was pressed, the return value is 0.

([[#Keycode|View key code]])

====int waitkey( void )====
Wait for a key, and return the key code.

It is a simplify of getkey 
([[#Keycode|View key code]])

====int iskeydown( int keycode )====
Checks whether the specified key is pressed. 
The parameter is a key code of the key that you check. 
When you wait events only by this function, the calculator never turns off. Only use this function when you need to wait for key input to continue. 
If the specified key is pressed, the return value is 1. 
If the specified key is not pressed, the return value is 0. 
([[#Keycode|View key code]])

====void sleep( int millsecond )====
Suspends the execution of the current thread for a specified interval.

===File name format===
A few examples to illustrate the format of the file name:
File named 2.txt in the Storage Mem in the root directory is "\\\\fls0\\2.txt"
File named 2.txt in the directory book in the Storage Mem is "\\\\fls0\\book\\2.txt"
File named 2.txt in the root directory of the SD card is "\\\\crd0\\2.txt"
Directory book in SD card is “\\\\crd0\\book”

In this moment you can’t operate the file in Main Mem

Note that the filename is case sensitive!

\exemple\FILE.c shows how to operate file

===Keycode===
The following definitions are declared for some common key in fxlib.h

<pre>#define KEY_UP 30018
#define KEY_DOWN 30023
#define KEY_LEFT 30020
#define KEY_RIGHT 30021
#define KEY_EXIT 30002
#define KEY_AC 30015
#define KEY_DEL 30025
#define KEY_EXE 30024
#define KEY_SHIFT 30006
#define KEY_ALPHA 30007
#define KEY_MENU 30003
#define KEY_OPTN 30008
#define KEY_F1 30009
#define KEY_F2 30010
#define KEY_F3 30011</pre>
