Welcome to Casiopeia!
Our name is inspired by the constellation "Cassiopeia", and is suggested by yeongJIN_COOL, taking advantage of the beginning of the word cassiopeia be very similar to the word/brand casio.
If you want to program for casio calculators you're in the right place! We are a young, but active community.
Casio Prizm OS 2.00 Update
This week was released the OS 2.00 for the Casio fx-cg10/fx-cg20 (known as Prizm). Found originally by TeamFX, this new major OS update introduce mainly some new math features.
Let us know them?
The FX-CG20 now supports vectors in the natural representation.
New commands for calculate the inner product, cross product, unit vector, norm and angle were added as well as new memories [from A-Z] for storing vectors.
Improved graphical resolution of integrals
The latest software version 2.0 makes more flexible the graphical resolution of integrals. Integrals can be solved between all significant points now. Intersection and zero, zero and manual value, everything is possible. The values determined for the integral and also the values of the surface are computed interactively!
Standard deviation and variance
Two frequently requested commands are now included in version 2.0 of the FX-CG20. The commands for the popular standard deviation [ StdDev_Sigma() ] and popular variance [ Variance_Sigma2() ] can now be found in the calculator.
Random queries from lists (permutation)
In the new software version 2.0, is possible randomly get existing lists values with the new RanSamp# command.
Improved Equation Solver
The application for the resolution of equations and equation systems give in the software version 2.0 much more detailed results. All results are now in natural representation and also the results for not clearly solvable equations are now more meaningful.
New add-ins: Russian Language and ProbSim
In addition to the new OS 2.0, were released some new add-ins.
ProbSim: For Prizm and fx9860GII
This new add-in is created to perform random tests simulating dice, urns, or playing cards in a clearer, faster and easier way. Various experiments in the field of random experiments can be simulated. The parameters of the individual experiments are updated during the same in real time and displayed for exemple in histograms.
Russian Language add-in for Prizm
Was also released a language add-in for casio prizm, that add a new language, russian to the available languages.
Some other existing prizm official add-ins have been updated.
Update for Casio FX-9860GII in spring 2014
Also the CASIO FX-9860GII will be updated, according to Casio Schulrechner during the spring 2014. The update will include:
• Automatic parentheses
• Vector Calculus
Both features were initially implemented in Casio Prizm OS, version 1.04 and 2.00 respectively. It's good to see that fx9860GII is not forgotten.
I'm looking forward for this update.

During this month, Planete Casio and Casio Calculators organized free programming lessons to beginners.
These tutorials are grouped into three parts each of three tutorials, with a game in the end of each part. You will see "Questions for a Champion", "Run & Jump", and "Mini-golf"
These lessons are writted in french, but you can always leave a "like" on Facebook.
You can download tutorials from Planete Casio.
Have a good holiday !

When powering off your fx-7400Gii, fx-9750Gii, fx-9860G or fx-9860Gii, you are shown a nice Casio logo.
This logo is in fact a BMP image included in the OS - and from now on, a new tool is going to let you overwrite that image!
You can now fully customize your Casio calculator - why not putting an image with your nick in order to prevent theft?
The BMP image has to be in 128 x 64 pixels, with 1-bit color depth.
This format is refered as "monochrome Bitmap" in some softwares, and in other softwares you just get it by setting an indexed image with a 2-colors palette.
For exemple, GIMP is able to read this format although it won't accept to write it as far as I know - but the simple Microsoft Paint everyone has with Microsoft Windows is able to do it!
And for those who won't believe in a single image, here's the video:

The fx9860g serie of Casio calculators was designed to be used especially in high schools and contrary to Classpads it has no CAS.
During the last few years some developers have tried to create a CAS add-in for fx9860g calculators.
The first was kucalc (if I'm right) from UCF with symbolix in 2007. Symbolix has a good user interface and can do some algebra but as it is a beta version, contains some bugs.
After was created other cas add-in known as "jeuxcasio cas" by Alexis and Pierrotll. It is more reliable and stable than Symbolix. The last update was in 2008.
But now there is another alternative. Some days ago, Diameter released in CnCalc.org a port of Eigenmath Cas engine to fx9860g. It can derive and make much more such as simplify, roots...
Contrary to jeuxcasio CAS add-in, in Eigenmath fx 1.0 symbols like π (pi), √ (sqrt), cos, tan, sin and others are not (yet) associated with the calc keys and there is no function catalogue. Anyway I have to congratulate the author, he did an impressive work (again).
