The mathematical functions of the Classpad fx-cp400 are quite similar to the previous Classpad 300/330 models as we expected. However, there is no reference about 3d graphics in that description (and none icon in menu screenshot).

Were disclosed the dimensions of the new classpad: 89 x 206 x 21 mm. It is slightly longer than its predecessor with the dimensions 84 x 189 x 21 mm, due to having a larger screen.

According to this store, calculator package should include:
Casio FX-CP400
Calculator-Calculator 3pin cable
Classpad <-> Computer Cable (USB)
Windows software CD
Quick Start Guide
Protection cover
Batteries (4 x AAA)

The first units are expected to hit the European (or at least German) stores in June. The calculator was also announced on China, middle east/asia, Russia and Latin America where should arrive during the summer (undefined date). Australia will receive the fx-cp400 in August. Although it was also announced in USA there is no release date yet.

The price that the source report is CHF 199.00 (≈ 160€) and dynatech.de speaks in 149.95€. I bet that the average price will be between 150€-160€ (and may change from country to country, depending eg taxes).

Were also published two new images using cas:

View the latest post Fruit Ninja reaches the Casio Fx9860!


A few months ago, Deep Thought adapted the famous iPhone game (Fruit Ninja) for TI-83+/84 calculators using the keys as input (since these calculators do not have touch screen).

Afterward, Dark Storm (from Planet-Casio) began working on a similar project with the aim of bringing fruit ninja also for casio fx9860.

He managed to make a pretty faithful adaptation of the original game. The gameplay is impressive and the fruits have good fluidity and are quite realistic. The only less positive aspects are that sometimes is difficult distinguish the pumps and the controls are a bit difficult to use the first few times. But considering the limited device that we have (without touchscreen or colors) and that the game is still in beta the final result is very good!

If you like the game do not hesitate to test it and leave your comments!

Code: Select all

const unsigned int sc0135[] = { 0xD201D002, 0x422B0009, 0x80010070, 0x0135 };
#define ML_vram_adress (*(sc_cpv)sc0135)


revolutionfx: That's a bit different. Try to use the modified version of 0.3: http://www.file-upload.net/download-699 ... 5.rar.html
Note: You have to add the file revolution_asm.src to the source list and include "revolution.c" instead of "revolution.h".

More libraries are coming soon if I forgot one.

3. How have you used system calls?
If you use instant system calls or an assembler file (.src), everything is ok.
But if your code looks like this
code: Show
Code: Select all
static int SysCallCode[] = {0xD201422B,0x60F20000,0x80010070};
static int (*SysCall)( int R4, int R5, int R6, int R7, int FNo ) = (void*)&SysCallCode;
char* ML_vram_adress()
{
return (char*)((*SysCall)(0, 0, 0, 0, 309));
}

you have to change it.

View the latest post Casio will Release a new Classpad fx-CP400 with color screen

1, 2

Do you still remember the patents found by me one month ago? Yes they were real :o ! A new classpad (fx-CP400) is near.

Image


The fx-CP400, comes which a large touch-panel color liquid crystal display (LCD) for easy viewing and operability with the incredible resolution of 320×528. We really need a screen upgrade, the old classpad screen quality was not the best.

This calculator will competing with the Nspire CX CAS.

The new Classpad model will be available in various countries starting in early summer 2013 (i cant wait :P ).

Quote by Casio:
Tokyo, November 27, 2012 — Casio Computer Co., Ltd., announced today that it will release a new model in its ClassPad series of graphing scientific calculators, the fx-CP400, which features a large touch-panel color liquid crystal display (LCD) for easy viewing and operability. The fx-CP400 will be available in various countries starting in early summer 2013.

Casio has contributed to math education around the world by developing advanced calculators that make it easier to learn. In 1985, Casio introduced the world's first graphing calculator, the fx-7000G, and in 2004 the company released the fx-82ES scientific calculator with textbook display that shows fractions and root functions as they appear in textbooks.

Launched in 2003 with the ClassPad 300, the ClassPad series features a Computer Algebra System (CAS) developed by Casio and pen touch operations using a stylus. Products in the series have earned a strong reputation as graphing scientific calculators among both students and instructors involved in math education.

The new fx-CP400 is the first in the ClassPad series to be equipped with a color display. With high resolution of 320 × 528 dots, its 4.8-inch large color LCD makes it easy to observe mathematical formulas, graphs, and images, while realizing more comfortable operability.

The large LCD vividly displays mathematical formulas and charts and is highly useful for understanding the relationships between equations and graphical data because it can display them both at the same time. Moreover, as an all-new feature, the fx-CP400 enables users to switch between an upright view and a horizontal view, which is useful for displaying long mathematical formulas, at the touch of a button. Users can intuitively operate the calculator using the stylus on the touch-panel LCD, and input data using the software keyboard.

Large touch-panel color LCD makes viewing and operating easy
Image
Mathematical formulas, graphs and images are all vividly displayed on the 4.8-inch large color LCD in 320 × 528-dot high resolution. Users can check formulas and graphs at the same time on the display, making it easier to grasp their relationships. By enabling long formulas and charts to be displayed on the screen, the fx-CP400 is very useful for helping users better understand mathematics.

Users can draw graphic shapes on top of images to study such phenomena as parabolas produced by water fountains and the curvature of antennas. Combining mathematical functions with real-life phenomena in this way is bound to stimulate interest in studying mathematics.

Users can intuitively operate the fx-CP400 by using the stylus on the touch panel to graphically display mathematical formulas without complicated key operations simply by dragging and dropping the formulas into the graph area.

One-touch switching between upright and horizontal views
Image

Users can switch the display between an upright view and a horizontal view simply by touching an icon on the panel. The horizontal view is convenient for displaying a long formula on a single line.

Wide range of functions useful for studying

Image

Casio has redesigned the ClassPad series' software keyboard to make this new model easier to use, organizing functions to correspond to three levels of learning difficulty, beginning with basic functions used by everyone like fractions, square roots, and trigonometric functions, then advanced functions like differential calculus, complex compound numbers, and sigma calculations, and finally even more advanced calculations including piecewise and user-defined formulas. Furthermore, the fx-CP400 features a variety of functions designed to help students learn and instructors teach at school, including a USB mass storage function for quick and easy data transfer, and compatibility with Casio data projectors to enable the calculator's display to be projected on a screen.

Practical and stylish design

While featuring the same keyboard arrangement and operating style made popular by previous ClassPad calculators, the fx-CP400 is also fitted with keys that slope down from bottom to top, which helps prevent input errors when pressing vertically arranged keys. Stylistically, Casio has created an attractive calculator designed with a solid body and slightly oval shape that fits comfortably in the hand, and finished it in several shades of blue to evoke an intellectual look.

Specifications

Image



The casio just published the announcement on its Asia Website some hours ago and I with a bit of luck found him.
Casio Usa, Europe, Casio Education still have nothing published. We were faster than them :twisted:

I did a comparative table with the characteristics already known of this calculator vs. other casio calcs and nspire cx cas:

Image

This new model features plenty of improvements compared with the old ClassPad. Possibly it will be more powerful than the prizm ;) , but i still do not know the speed of the cpu.

And future Sdk's, development, etc?
Possibly this calculator will have a BASIC interpreter, with backwards compatibility from older black and white classpads (like prizm /fx9860).
About SDK, there is no information. Maybe we can get more info, when they release the calculator manuals (for we check for add-in support) .

So, what do you think of this new classpad?

I'll try to get more information soon :D
