What's new in OS ver 1.2?

[betoe]

I think that casio only fix some bugs.

[Lovecasio]

The new OS update (1.20) doesn't offer something new, it just has some bugs fixed, and allow SpreadSheet to run.
Some bugs that have been fixed ( fixed but I think that they were not developed for better performance ):
-Finding max, min in Main. Ex: tried fmax(-x^4+x^2+2), now it is Ok, but before, it crashes and the ClassPad restart.
-Differential equation solving ( dSolve ): If there are error, an error table appear instead of crashing and restarting.

That is what I found "new" in new OS 1.20. Oh, If you perform Initializing, the OS update isn't deleted.

Lets make a guess, friends, what is the next application and what is new in the next OS update?

[betoe]

Well i like a lot the spreadsheet app. When i know about that, i thought "why i need that shit?" but now i change my opinion and i think its great. With my AFX i used to make programs for make some operations for my exams, but now i do files for the spreadsheet and its more easy and fast.

Well maybe casio will release first the schip8, or give us the tools for make add-ins, ASM programs... I'm waiting anxious for that!.

[CrimsonCasio]

I've requested an official statement regarding the add-ins, I hope to hear something definative soon. Im hoping that once they realized that people would want to make apps for the classpad they decided to improve the installer... well, i can dream.

[betoe]

Hope you will have a good response about that. I want to play (not do, only play ) really and fastest games (like the ASM in AFX), and make best programs.

[betoe]

You can order your cd from: http://www.classpad.de/

[Daniel (CZE)]

I don't know why CASIO didn't give us some kind of SDK for ClassPad. Operating system is based on OS for Pocket Viewer S-1600 and ClassPad apps have almost as same header of file as for Pocket Viewer. So I think that it wouldn't be so difficult to create SDK (I've tried to import ClassPad OS to PV SDK without any success. ). It can be based on PV SDK which is really great. If a programming for CP would be almost same as for PV, we can expect many great and useful applications and games in a short time because an import won't be complicated. I've many ideas for mathematical programs...

(PV-S1600 is built on HITACHI SH3 CPU 30 MHz and 29,... MIPS. C language is used for programs.)

[Daruosh]

Where we can find PV SDK? I think can changes some properties of it to make it compatible for CP.

[Daniel (CZE)]

You can download it from this link...

PV-S1600 SDK

...and try it. (The SDK is freeware and you can download it from CASIO webpage too.)

[Daruosh]

Because of the CPUs of PV1600 and CP300 are the same (SuperH 7291), I think the compiler of them is same too (I think). But the App-Loader is different from Pv. If I could crack SpreadSheet Loader... .

Can someone help me?

[tonyp]

You can order your cd from: http://www.classpad.de/

I ordered an upgrade about a month ago and still haven't received it. I re-ordered another one yesterday, and will wait to see if this time it will oblige me.

tonyp AT acm.org

[betoe]

Well, i wait about 5 or 6 weeks, maybe a little more here in Mexico. I have heard that in the US the wait time is high.

[mkanter]

ok, i think i have all i need (except one thing: the chip8 add-in or another add-in).

on the classpad.org site are screen shots of the add-in, and the all were half-screen. is it possible to write full-screen chip8 apps? (The (speed and refresh settings should be made in an setup-menu that can be accessed by the icon bar.)

can someone help me and send it to me?

-----------------------------
My Webpage

[CrimsonCasio]

it hasnt been relased yet... do you have the add-in installer?

[mkanter]

no.
but there have to be one (how to they create the screen shots or test the chip8 apps?)

i got the spreadsheet cd today.
there is "addin.dll" i think it's used to transfer the add-in to the classpad. (because of the dialogs in it). but i can no japanese, so i'm not shure. (can't understand the jap. string table).

Then there is an file "spreadsheet.cpa" with an header of an PV add-in.
In the old version of the manager (and the one i'm using now) there is an file extention (contained in the code of the manager) which is *.pva
Yes, right pva! You may know what i'm thinking now: There should be an way the use the PV SDK to load the addins to the classpad.

[Daruosh]

I find out how can I upload some applications in to CP.
Run SpreadSheet300.Exe in CD. Click next the program to show you agreement dialog, check I agree and then goto your Program Files\Casio directory
you will see a folder named Spreadsheet with ClassPad 300 OS Update
rename your app to Sprdsheet300.cpa and copy it in to this folder, and continue the program setup!
But next problem is SDK and Complation Process.

[Daniel (CZE)]

I don't think that compilation is problem. Because ClassPad OS is built on PV OS, we can expect same functions for operating with basic hardware (display, memory etc.). I can create "Hello World" program and try to upload it to ClassPad.

[CrimsonCasio]

it impresses me that you guys are doing all this but you really dont need to...

[mkanter]

we won't stop until we got it
(or the casio guys on there throne will release the loader and an sdk)

And i don't understand why they don't do it. (the things exist already)

---------------------------------
My Webpage

[mkanter]

i looked into the files of the spreadsheet cd
the [0x255] is one sign - often used as token: ?

%programdir%/casio/Spreadsheet with ClassPad 300 OS Update/

Addin.dll
I think it's used to load the add-in to the classpad
2 exported functions:
CCXSetExchangeWindow2
OnApplication

it also has some dialogs, which look like these used in the manager to exchange the programs and eacts.

should that say something?!

backup.dll
i think it's used to backup the existing data from the classpad

exported functions:
CCXSetEchangeWindow (!)
CloseUSB (!)
GetVersionCode
OnBackupRestore
OnBackupSave

then there are the cpbasicfont.dll, cpboldfont.dll, enumdev.dll - these came with the manager too.

cposdata.bin
at the beginning:
SZDD [some signs] [0x255] CASIOPVO [0x255] S200U

at the end:
1.00:

it's the data of the os update
the file id is unknown to me
the next is interesting: CASIO PV OS 200 U
the 1.00 at the end can be an version information (not shure about that)

sprdsheet300.cpa
at the beginning:
SZDD (again)

and PVAPLHED V20

not needed to guess what it is.

osuplib.dll
exported functions:
osupd_GetDLLVersion
osupd_GetStatus
osupd_GetUpdateMode
osupd_GetResult
osupd_FinalizeModule
osupd_GetStatus
osupd_Abort
osupd_ExecuteUpdate (!)
osupd_GetFileStatus
osupd_LoadUpdateFile (!)
osupd_SetParameter
osupd_SetInterface (!)
osupd_InitializeModule

maybe this helps someone.

IF THERE IS AN JAPANEASE (OR ONE WHO UNTERSTANDS IT) MEMBER - LET ME KNOW I NEED SOMEONE TO TRANSLATE THE STRING TABLE.

----------------------------
My Webpage

[mkanter]

i found out that the szdd is an compressed file with the microsoft variant of the lembel/ziv compression.

extracted them and at the beginning of the spreadsheet.cpa there is:

PVAPLHEDV20


P  HSpreadsheet


at the cposdata.bin is:

CASIOPVOS200U

so it is an pv add-in
the cposdata.bin is uncompressed 8,62 MB (the complete size of memory the classpad has) - i think it's an binary image of the complete memory and try to find out if the offset are the same i found with the mcs file format.

marcel... i dont know how to hint at this any clearer without outright saying it...

ah well, if you dont have anything better to do it couldnt hurt, just trying to save you some effort

[Daniel (CZE)]

I know we can wait for add-in loader for ClassPad but this discussion is quite interesting.

I don't think ClassPad has only 8,26 MB of memory. It can be image but only of RAM! PVS-1600 uses 8 MB RAM (addition to 16 MB FLASH). When you turn on PV, whole image of OS is copied to 4 MB RAM (after it OS is faster and we can't modify a source, only this image). 2 MB are reserved for running application and 2 MB are reserved to store temporary data.

I think ClassPad is same.

Size of ClassPad's OS and PV's OS is almost equal.

CrimsonCasio: Please, tell us when we can expect add-in loader. I think you know it. Pleeeeaaaasssseee

[Andy.Davies]

i suppose it gives you somthing to write on you CV

...haked PV OS to make it work with my Classpad....

it might impress some employers

[CrimsonCasio]

im sorry, I cant elaborate till next week.

[betoe]

I know we can wait for add-in loader for ClassPad but this discussion is quite interesting.

I think the same, i read this with a lot of interest.

[Daruosh]

Hey everybody I have Upload Hello World Application to my classpad. Yohooo
If you want details about compilation contact me at Daruosha AT Yahoo.Com
Addin.DLL is evrything you need to upload your app + my Upload Program.

[CrimsonCasio]

Please post them, im sure everyone is interested, you dont what to get hit with that many e-mails

[mkanter]

Report from R.I.P. Service (Raw Information Providing Service):

things found out after the os update to 1.20:
the classpad may has definetly more than 8MB !!!! of DRAM (maybe 16 or 32 MB.)
the value showed in the debug menu EXP' />[y][on/off] is now 16777216 (16 MB) before it was 8388608 (8MB).

there is an 5*7 font (same size like the one on the cfx) on the classpad. (don't know how to enable it - but the icon bar is made with this font)
and the other things (the menu, main, graphic, program editor, ...) are all add-ins!
yes, add-ins! the name for main is runcas.pva

@darush: which programming language did you use to write the program?

[Daruosh]

Complie your program with compoler provided by PV SDK, rename its extension to cpa, change the first 12B of header with SprdSheet.cpa.
Use Addin.Dll to uplaod your application. you can download my AddIn Loader from http://www27.Brinkst...spad/ADLoad.exe
I developed it with MS Visual C++ .NET (MFC 7.0).
I couldn't use SHPV LIBRARY.
Or you can use OS Update program in CD.

PS: Memory map of PV 1600 is [B]same as[B/] CP.

News ABout CP OS:

What is PVAPLHEAD in SYSRAM directory?
I found that CP OS has following directories:
sysram
sysram\bin
sys00
PVROM

CP OS 1.2 has unactivated ALARAM and clock (I think)
Refer to 0x00087AC0 at 41

Some structures of CP are simillar to SHPV Library like
CPRECT
BinaryMathObject
and somthing like Templates in C++ (i coundn't find how it works!)

I'm going to upload PV 1600 on CP (I think I'm crrazy)
Does anyone know how can I find PV1600 OS?

also sys00\bin\EXPENSE.PVA Application!!!
Why CASIO hide these informaton form developers!

you can use CPU7291.DLL to test your application.

Becase of some bugs I have removed ADLoader.exe form my web site. I will upload it as soon as possible.

[Daniel (CZE)]

Hi,

I don't want to support you to upload PV OS to CP but there is your link:

PV-S1600 OS (original)

I have also source code of PV OS but I can't give it to you.

also sys00\bin\EXPENSE.PVA Application!!!

I think this is some kind of CASIO mistake.

[CrimsonCasio]

Ok guys, Ive been given permission to anounce that Casio WILL i repeat: WILL be releasing SDK for the classpad... Ive known about this for months but i couldnt tell (i was also hoping casio would officially anounce it on the forum ).

you guys dont have to worry about doing it all yourselves (i tried to hint at it and save you the trouble...) but if you want to continue for fun go ahead... just be aware you dont have to worry about it, casio is working with us this time .

latest news is a it will be released at the beging of summer.

[Daruosh]

Do you when the NEXT OS version will be released?
I think courrent OS has some bugs tthat make Classpad untrustworthy!!

[johnet123]

Goto http://classpad.net/ and there you will find ClassPad OS 1.24

[Daniel (CZE)]

And there is also add-in installer!!

[Lovecasio]

They come out at last.
Are you happy? You must if you like your ClassPad.
