I have just started using AVR Studio (Ver 6) for C++ programs.

 

I am having a problem with include files. The files show in the project window but compiler says they don't exist.

 

What must you do to use include (.h) files with this C++ compiler?

Why have you started with v6 ??

 

v6 was superseded by v7 several years ago!

 

The files show in the project window but compiler says they don't exist.

You use the 'Include Path' to tell the compiler (or, to be pedantic, the preprocessor) where to find include files.

 

 

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected

Welcome to AVRFreaks Bob.

 

Atmel Studio, not AVR Studio, is at version 7 now, you should uninstall AS6 and install AS7 instead.

 

How have you tried to include the .h files?

"I may make you feel but I can't make you think" - Jethro Tull - Thick As A Brick

"void transmigratus(void) {transmigratus();} // recursio infinitus" - larryvc

I am still running WinXP. When I tried version 7 it would not run on XP.

 

I have my include files (.h) in the same directory as the main program.

 

Where do I set the path to the include files?

 

I have been a C++ programmer since 1989. Since 1998 I mostly used Microsoft VC++

 

I have been programming the Atmel chips in assembly language since about 2005. I previously use version 4 and 5 for assembly.

 

I recently upgraded to version 6.

Atmel Studio is built on Visual Studio - you should recognise it!

In the Project Proerties > AVR/GNU C++ Compiler > Directories

If the header files are in the same directory as main() they should just be found if you #include "name.h"
