The trial version of the Casio Classpad II (fx-cp400) emulator was released to the public giving opportunity to start exploring this new calculator.

The menu of the calculator consists of 14 icons: Main, eActivity, Statistics, Spread-sheet, Graph&Table, Geometry, Conics, DiffEq-Graph, NumSolve, Sequence, Financial,Program, Communication and System:

There is compatibility with eActivities and Basic Programs from previous classpad models.
Was introduced a new casio custom image format, .c2p, to use as custom shutdown image or as graphs background.

We were the first unofficial source in November 2012 announcing the new Classpad fx-CP400, the first touchscreen color graphing calculator.

Today we would like to share more details about this revolutionary calculator. A switzerland store revealed new information concerning the new Casio Classpad Fx-Cp400 (especially related with mathematical functions).

-Large color LCD display (320 x 528 pixels, 64k colors)
-Pen/finger touch screen operations
-Rotating screen by pressing a key (main application)
-Division of the screen into two windows to the application using a variety of editing functions such as drag & drop, copy & paste, etc. by a stylus operation
-Direct functional link between the applications on icon selection (one-touch)
-Virtual keyboard with mathematical functions, keyboard letters, special characters and catalog of all commands
-Natural mathematical notation
-Selection of given mathematical expressions to input the coefficients
-Icon menu
-Connection with PC via USB cable and calc-to-calc via 3-pin cable (included)

Functions
-Algebraic and numerical computing

-Numerical solution of equations
-eActivities (electronic documentation tool for teachers and workbook for students)
-Basic programming
-Communication with ClassPad, PC, EA-200 and Casio Projectors
-User-selectable language

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:

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!

I found an easy way to make addins PowerGraphic2 compatible. Here's a step-by-step guide:

1. Have you used IsKeyDown or IsKeyUp?
add this code on top of your program:

2. What libraries have you used?
mylib: It works without modifications.
MonochromeLib: replace

code: Show

by

code: Show

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

you have to change it.

Casio has launched two programs this week for Mac Os X
-> Fx-Cg Manager Trial
-> Casio Prizm Picture Conversion

A few years ago, they just release software for Windows, that had the highest number of users.
However in the last years Apple and its OS has grown a lot and they are following the trend of the market and consumers.
