Casio Usb Power Graphic 2 SDK Info

[helder7]

The "IsKeyDown" function in "fx-9860G SDK Libraries" has been deprecated and is now
unsupported in "USB POWER GRAPHIC 2" version of "fx-9860GII(SD)",
"GRAPH75(95)" and "fx-9860G AU PLUS".
Instead of "IsKeyDown", please use "GetKey" or "Bkey_GetKeyWait"(new function)
according to the use cases illustrated below.
The following use cases are only examples, “GetKey” and “Bkey_GetKeyWait” are not
guaranteed to perform identically to “IsKeyDown”.


Case1: Poll key state until a particular key is pressed
・Code example (using "IsKeyDown")

Code: Select all

while (1){
if (IsKeyDown(KEY_CHAR_0)) break;
}

・Code example (using "GetKey" instead of "IsKeyDown")

Code: Select all

unsigned int key;
while (1){
GetKey(&key);
if (KEY_CHAR_0 == key) break;
}

Case2: Check to see if a key is pressed (with an optional wait/timeout)
・Code example (using "IsKeyDown")

Code: Select all

int flag0 = 0;
if (IsKeyDown(KEY_CHAR_0))
flag0 = 1;

・Code example (using "Bkey_GetKeyWait" instead of "IsKeyDown")

Code: Select all

int kcode1 = 0, kcode2 = 0, flag0 = 0;
short unused = 0;
if (Bkey_GetKeyWait(&kcode1, &kcode2, KEYWAIT_HALTOFF_TIMEROFF, 0,
1, &unused)==KEYREP_KEYEVENT) {
if ((kcode1==7)&&(kcode2==2)) flag0 = 1;
}

All the details in the attached pdf. Perhaps many games/applications will not work on new model fx-9860 USB POWER GRAPHIC 2

The new models are based on the Prizm-MPU (SH-7305), which port addresses are completely incompatible compared to the old MPUs (SH-7337 or SH-7355). Though, the syscalls are still supported with OS 2.02. Any addin, which bypasses syscalls by using direct SH-7337- or SH-7355-port access will fail.
BTW: the fx-9750GII, which I recently bought, has not even the label "USB POWER GRAPHIC 2". The new models are detectable by the OS version 2.02, only (or by inspecting the board).

Oh shit I used this functions in all my addins ! Why can't Casio respect compatibility ?

[SimonLothar]

...Why can't Casio respect compatibility ?

To be fair: they did...in case of the fx9860-series! The syscalls predominantly are compatible. Programs should rather not rely on hardware-implementations.

Bfile_GetMediaFree() doesn't work either.

Bfile_GetMediaFree() doesn't work either.

0x042E: int Bfile_GetMediaFree_OS( unsigned short*media_id, int*freespace );
This call is not compatible any more on USB POWER GRAPHIC 2 calculators, because these machines support up to 32 GB SD. The old interface does not fit.

freespace has to be a pointer to a 2-element int array (t. i. int64)

int freespace[2]

Thanks Simon. Same syscall works for GII and GII-2, but free space is in freeSpace[0] for GII and in freeSpace[1] for GII-2.

does the pdf in the op still exist?

yes, is attached in omnimaga and is available in casio edu downloads (Graphic calculators > SDK > [PDF file] SDK_Announcement.pdf).

I still can't find the pdf. Is it online anywhere?
