Ever wanted to create applications that interact with your Casio calculator in realtime ? Give your calculator internet access ? With CasioIO you can do it all !
The core of CasioIO is a dll (casioio.dll) which handles the low level communication with the calculator.
All you need to start is the CasioIO SDK, which you can download here freely (123k).
CasioIO should be accessible from every programming language that supports dlls. The two most important are Visual C++ and Visual Basic.
