ti vs casio
Posted 16 December 2004 - 11:07 AM
And about programing, SYSRPL is extremelly powerfull, no error checking and most functions are directly written in ASM so it's almoust as fast as ASM and much easyer to program, not mention that we (HP users/programmers) know the exact place were that functions are in the rom and we can program on calc.
Anyway i use my hp mostly for math/engeneering so the degree of freedom i have while using it makes that calc the best FOR ME.

On the (A)FX you can code in:
so you don't have "MORE" lanuages but we have the better ones since
the AFX/FX uses a 286 compatible processor.
So porting from PC to Calc is quite easy.
And yes, we can change keys using ASM to change the keyboard interrupt and this way reprogram the keys.
And about changin the OS. Well ok this is on the ROM and therefor can not be changed but anyways we can patch into it using the interrupts
and therefor change pretty much everything (if we only knew where "everything is ).
On the HP49g+, you can program in User RPL, Sys RPL, a crappy form of BASIC, Saturn ASM, ARM ASM, and C. In addition there is an old version of a Pascal compiler but o one uses it.
The OS is flash and has no protection whatsoever. You could overwrite OS if you wanted to. OF course interrupts and the like can be adjusted easily. HP even provided the basic OS API for free.
"so you don't have "MORE" lanuages but we have the better ones since

I'd call a 203MHz ARM a bit better then a 286. ARMs are used everywhere these days; they are an extremely popular CPU for embedded systems.

As for the rest you might be right

casio basic suxx hard, i have a 9850gb+
math functions are... ok, but basic
i already overclocked it to 8mhz and upgraded to 64kb
a friend even did it with a switch, so he can still use the link function!
Could you PLEASE tell me how you overclocked a 9850gb+ . As far as i know i thought this was impossibe, iv only seen websites where its done on Ti calcs!!?

There is a link to a german page where someone has
overclocked hios calc (doubled the speed) and doubled the RAM.
Unfortunately everything is in german and the OC is not explained at all I think.

*want to carry a quite huge box with you
*can create PCBs with Graphics Controllers and LCD controllers and so on
I think it is quite difficult. WHy do you want to do this?

i personnaly dont know of anyt site to build a graphic calculator, and personally unless you are brillinat at asmbaly language, soldering, electronic theory, and Maths i dont think its possible.
Posted 03 March 2005 - 03:48 PM
I could start from there...

This is 100x easier then building a scientific calculator.
* buy a microdontroller and learn how to program it. Ideally use one that has a free C compiler and a floating point library. AVRs are good for this sort of thing
* buy a character LCD based on the stadard HD44780 chip. Connect it to the micro and make it say "hello world" to learn how to use it.
* buy a premade matrix of keys. Learn how to read specific keys by scanning the matric
* write software for your calculator. RPN is much easier to implement. Using C will help here.
* Create a custom machined case if desired.

Better dont waste time, get a job and buy one calculator, it will be the best way (and cheapest) and the final product will be better.
I totaly agree with you betoe. And finding a Free C compiler for a microprocessor isnt easy, unless you break the law And again to make a scientific calc you could buy one.
on the other hand just make a normal calc, i think that is alot easier and possible

Nonsense. Have you ever heard of GCC? It targets more then PCs you know.

on the internet since not many people are interrested to build something that will probably be VERRY expensive and VERRY difficult to make if they can get it for a tiny amount of that money pre-built and 1000 times better ...

EXCEPT.....i get really angry wif this as it take all the fun out of the calc.....the CASIO BASIC is pure KRAP. If only u could program assymbly(without using new rom chip and hacking) on it then it would be fun. Im stuck having to figure out better ways to program graphics using stat graphs and lists, being as conservative as possible in my games in programs. The only pro of this is it teaches u to program better. I feel sad for every programmer that buys the cfx calcs and thinks WOW, i can pogram games on it,,,,,but soon finds out the horrible truth when plotting pixels on the screen for the first time and seeing it plot at 2 pixels per second. That sort of thing makes u feel sick, its just pure evil

In hardware, AFX 2+ is more powerfull, but weak software
Posted 19 March 2005 - 08:48 PM
So let's make better software

Developing a better software requires MONEY & TIME.
I dont think so,
all u need is one university student on holiday so has plenty of time and the will to do it.
edit : ure definatly right about the time part

In my oponion...TIs are best for doing numerical and symbolical operations.
I am using ti89 and hp49G emulators, and I think the the numerical equation solver of HP is more powerful than TI one...It can solve equations including "arg" or "abs" of a complex expression, with no problem.
Besides, there is also a library for solving nonlinear equations sistems...very useful.
Has TI89 something like that?

Casio Basic is as useless as tits on a Bull,
or a broken pencil...........pointless

Hou You can see I am seeking for a new model (TI or CASIO) and I ask for help, telling this to all:
- I have no restrictions for exams or others, when I need I can use my CASIO fx-82MS;
- I need to work with complex numbers in matrices, vectors, polys and liear systems (entries and answers);
- Graphs are wellcome;
- Durability is very important (because I'll work without any warranty);
For all: If you click in this site (official of CASIO in germany) http://www.casio-eur...hner/vergleich/ you will see the comparison between two models directly or the PDF file. The duel ALGEBRA FX 2.0 PLUS versus Classpad 300 is very interesting. ALGEBRA FX 2.0 PLUS loks much better to me.
I hope You all give some hopefull information for me as I see many times in this forum. Sorry about my english. I'm learning to stop with theese translators because They are sucks. .
Thanks for all.

One word: This is no fair comparison by any means.
7 words too many~
