Graph3DP v1.0 RC 1; Prizm Hacking Continues

(1/3) > >>

KermMartian:
I'm not sure if anyone at Omnimaga is still doing Prizm hacking, but I figured I might as well cross-post this in case any Omnimaga Prizm coders haven't yet been glancing at Cemetech's recent Prizm work. At any rate, I'm proud to present the first public beta of Graph3DP, a 3d graphing application for the Casio Prizm. Enter one to six 3D equations Z=f(X,Y) in terms of X and Y, adjust the window as need, and spin and zoom the resulting graph! This public beta demonstrates most of the major features of the program, including entering multiple equations, graphing, adjusting settings, and even tracing graphs. Additional work is still to be done on many of the features:

:: Debugging and expanding the parser
:: Debugging input routines
:: Adding the zoom menu
:: Adding real-time zooming
:: Improving the rotation algorithms to support dynamic axes
:: Complete tracing features
:: More graph-coloring schemes.

Give it a download and try it today! In other news, Cemetech's developers have been hard at work expanding Cemetech's WikiPrizm reference resource for Prizm users and programmers alike, and have been ardently working to learn more about the Prizm's hardware. Ashbad and myself, aided by Fishbot, new Cemetech member brijohn, and others, have been working with things like overclocking and directly accessing the data lines in the Prizm's serial / I/O port. Brijohn, using his experience with Casio's electronic dictionaries and translators, correctly pegged the CPU core as an SH7724 chip from Renesas, whereas previous guesses had ranged from the SH7721 to the SH7730 even to the fx-9860G's SH7705 CPU. With this information, Ashbad has now succeeded in tweaking the CPU speed in software, and will be reporting further findings soon. I'm poring over possible port numbers to determine how to poke the MSIOF port; if I'm successful, bidirectional transfers on both the RxD and TxD lines might be possible, meaning that CALCnet and stereo audio might be coming soon.

FinaleTI:
Awesome! I'll definitely give this a try sometime soon!

I'm glad to hear about all the discoveries related to Prizm hacking. I suppose I really should start learning C...

jwalker:
dont worry, im still here
ive just got caught up in all of my other projects and learning :P

DJ Omnimaga:
Wow this looks great Kerm. I have seen the photos a while ago and I'm happy it has progressed more. I hope to find some time to try this while I'm not lost into ice hockey forums. Many people complained about the lack of 3D graphing on the PRIZM and how they might go with a TI-Nspire CX instead. Not that I discourage a CX if you want nDoom and the nintendo emulators immediately, but the PRIZM has much more freedom for programming, thanks to Casio being more lax on 3rd-party development. :)

By the way there are some people still doing PRIZM hacking, but not as many as Cemetech and they're pretty busy (such as Reo and Qwerty.55). Z80man moved on to other interests due to lack of time. D: (A bunch of people got the calc recently, but I guess school happens x.x)

EDIT Also I think another reason why there is so few PRIZM dev lately is because there's a new French 83+ contest every few month, so most people work on their entries instead.

ruler501:
Now that we have 3d graphs we need a CAS :P

This is pretty nice. I'm learning C/++ so I will start hacking on the prizm soon enough.
