    Graph 35+ and Classpad 300

Posted 01 May 2005 - 05:10 PM

Hi, I'm Neuronix, a new member and this is my first topic here :D

Well, i got a nice and pretty gray thing on ebay that was what i was dreaming for since i found a ad in a magazine for the c300...of course i ripped the packaginig open with enthousiasm..well the first deceptions came with a simple Line,x,y,x1,y1...then it got even worse when i tryed to adapt my g35+ 3D program on the classpad and i found out that just creating a list on the c300 seems you are asking it to calculate 1987^152484...

Am i stupid or is the classpad really slow? <_< GetKey, matrix's, Lists, is there some way of using these things in a program or are they just there to fill the menu ??? :banghead:

So far i hate the classpad, i just can't stand it! slow slow slow :die:

have you downloaded the OS2.0, it fixes a few bugs with the lists and matricies... though not all of them. I have high hopes for the future of the classpad but i agree that it is not yet up to where it should be. however, there are many good people working on the classpad so I'm confident that eventually it will be at par or better than any other calculator, but at the moment it remains not much more than un-tapped potential... hopefully that wil change soon, and in the mean time we have the SDK to play with. :)

Yeah; i installed the v2.0, didn't change much though, i tried programming a simcity...1-2 secs to check if Matrix[a,b]=0 with a 21*21 matrix...i just can't wait to get XP to try the SDK, basic on cp stinks! What a pity, a real waste of such potential....

By the way how is the cp300 compared to the best Ti's and Hp's? i'm thinking of the v200 for exemple or the 38-48 HP series that have got 75Mhz processors O_O...

Anybody coming up with a good add in soon? i'm impatient to see someone good (like you Crimsoncasio :bow: : Caspaint, MLC language...i can't find a site where one doesn't see your name ^_^) come out with a really mean Add in, like a Wolfenstein ( what about M.Lamarche and his projet? haven't heard of it since the 3D maze he made) or a cool racing game ^_^ or just a simple Mario game, a little more interesting than the Chip8's "Ant". I'm hoping to join the SDK lovers soon ^_^

there's a trick you can use to replace matrixs with strings (much faster). or lists (also faster but requires more code).

try this:

if your matrix contains only numbers 0-9 then you dont need any fancy tricks, just stick them in a string and read them back with StrMid and return them to number format with strToExp(). in this way its like storing everything in a list. if you have numbers bigger than 9 you will have to turn those numbers into a character, then store that character to the list. use NumToChr for this. beware though, some numbers do not have characters associated with them, so you may put in a number and it will return a "", which will mess up your whole string. however, you only have to worry about this for numbers greater than ~50 (mabey higher), and there is a fix that allows you to store numbers up to almost 1000 in a single character in a string.

for this method i suggest you download CGF, it has with it a string containing every character in the classpad, you can use this string to store huge numbers:

//this string will be called "code"
//"a" is a string containing some unknown character

StrSrc code,a,num //looks in code for the contense of "a" and returns its numerical placement.
retrn(num) //stdlib return function, sets var RTN to the value of num

in this way you can convert a character to a number, but if you use this method you must not use NumToChr, use this instead:

//num is some number between 0 and 1000

StrMid code, num, chr, 1 //chr now contains the character at "num" in the code string
retrn(chr)

using this method both saves space (strings are smaller than anything else used for mass storage), and faster. take a look at CGF if you want examples of how to use this method. :)

CP Basic is slow, but its also very powerfull, remember to use # and the stdlib and you'll find you can do a great many things. ;)

It's no speed demon, that's for sure. I used to own one but sold it since the screen was too dim for me to read at all and I really don't like the string subroutine calls rather than using string functions. If the contrast has been improved in later models or if they added backlighting, I might take a look again
