Hello,
I just bought your EDU05 educational system and I find it very interresting but I have a problem to write the C++ instructions.
I’m new in C++ programing but I know other procedural languages. It is very difficult to me to write the instructions in the beginning of the program;
Is it possible to give me a very short example of program in C++ to, for example, write a message on the LCD board?
Thanks.
At the moment there is no C++ example code available for the EDU05.
A simple example can be done anyhow.
What is your favorite C++ compiler?
Do you like to make a console application or Windows Forms application?

I use DEV C++ Compiler version 4.9.9.2 from Broodshed Software and I like to make a console application.
Thank you for your answers to my question!
Now the Dev-C++ example for the EDU05 is ready.

Great!
Its just wat I needed!
Thanks for all!
Hi! I use Dev-C++5.8.2 and get an error when runnig your C++ example (Error to open/read EDU05D.DLL). The .exe file works fine. Is there a special location neccesarry for the DLL on a Windows7 64bit PC?
Yes, please put it to Windows\SysWOW64 folder or to the same folder with your project files.
I tried both and get always the same error with code -1.
Please compile a 32 bit exe.
The EDU05D.DLL is also 32 bit.
It is not “found” if your application is 64 bit.
That’s it. Thank you.
No problem. Glad it’s OK now.
