Hi Guys

just bouthgt (hardly!) the last Algebra FX 2.0 in Tokyo. Target: programming in C and asm.

Well, I went through a couple of French sites - amazing how they dissected the machine!

But some details remain obscure... for instance
- how to use the API from the Basic (and the maths functions like Cos, Sin... or simply *)
- or other architectural points...

My question/hope: can I expect some more information from any English site -

please let me know which ones deserve to be visited in order to complete my AFx2 system knowledge...

Thanks

This is by far the best english site, if you know french another good site is www.graph100.com .

bye the way, you are the first japanese person we have had on this forum.

Actually I'm not really Japanese even though I live in Tokyo.

Anyway, will have a deeper look to this site.

Arigato ..

[CrimsonCasio]

oh well, your still the closest thing . bye the way, I used to live in japan.

Hello,
using Basic API is not important/useful to us because it is terribly slow,
if you want trigonometric functions then tabelarize its domain multiplied by a constant
and thus use fixed point math which is the fastest (FX is not a 4GHz Athlon you know).
For example
int SinTab[360]={...}; // values of sin() function multiplied by 256.
It is a very common trick known from older PCs.

You live in Japan, so I can assume that you can understand all those #$%^@ (japanese ),
so are there any ASM/C specific CASIO related sites or they aren't interested in it?
Casio AFX 2.0 has an Easter Egg that lists some japanese names (probably engeeniers), do the following:
Go to the System menu then pres Shift' /> and then - the list will be displayed.
Have you any idea how we could contact them?

PS. I always wanted to visit Tokyo (from Poland).

[CrimsonCasio]

did you know about Shift' /> 1' /> and Shift' /> 2' /> (in the system menu) ?

[Mohamed]

Just always remember I'm offering a translation service between English, French and German.
And I only did that to help people like you get going.
So, just tell me about any French documents you'd want me to translate, but please no PDFs else if it's only text.

happy birthday Mohamed

You can have all (I think so) the possible functions in BASIC when you press CTRL' />+F4' />=[CAT/CAL]

[betoe]

How did you learn that key combinations?

What is the Shift' /> + 2' /> ? i dont understand it...

[CrimsonCasio]

in the system menu hit Shift' /> then 2' /> (or 1' /> ) and if takes you to some hidden screens, I dont know what Shift' /> 2' /> does yet (i dont want to mess with it and erase my memory), but Shift' /> 1' /> shows program versions.

[betoe]

right, in Shift 2 i wrote some numbers to see the results but i dont obtain any conclusion.

[CrimsonCasio]

try 0563

[betoe]

I made it (try 0563) but i dont see anythin special... only that in version appear a different number than the .20 .

Thats weird, when i read the replies of Crimson and Roender in this topic, i dont read well and i try the keys combinations on the calc. main menu, but then the calculator gone crazy

On the main menu, when i want to shut off the calc, this goes frozen and then i need to push the P button. This occur repeated times, i only can shut down the calc. in the "System menu". I also try to shut down the calc. on the RUN/MAT mode but the calc dont get off. I check the AC button on the F6' /> + + AC/on menu and its OK.

Then i try again in the RUN/MAT and now its ok.(i dont know what i do exactly)

a very difficult bug! let's send an email to casio!

[betoe]

To whom I direct the email to him? It would have to be to Casio the USA because here in Mexico there are only simply distributors and it would not interest to know this bug.

[Endi]

I think it would be better to send to USA and Japan. Japaneese made this calculator, so they have the biggest knowledge about its architecture.
It doesn't mean, of course, they will answer you.

[CrimsonCasio]

actually I'm in the middle of a 2 day phone conversation with casio, they are trying to figgure out the problem with the Classpad Manager, if I get a chance I'll ask them about it.

[betoe]

the classpad manager = software of emulation and for send-receive files from the calc?

[CrimsonCasio]

exactly.

[Brazzucko]

I don?t know if they are really interested to know about this bug, see for example the new CFX calculators, they have exactly the same hardware and probably the same software??

Now if you tell then that there is some guys buying the FX 1.0 and tuned it to one AFX 2.0, now I thing that they will be worry about it?.

[ross8653]

anyone ever ask them about the freeze bug i found
download it

the sad thing is i made this programming tetris then stripped all the crap between the loops out of it. There was something similar with the older calcs too
