Macro __AVR_ATmega2560__ not recognised

Hi,

See attachment below. why is the code section with the if defined __AVR_ATmega2560__ not recognised while the board Mega2560 is selected.
When I remove the comments at #define __AVR_ATmega2560__ it is recognised. But that is not desirable
By the way. I use VS 2022 on a Win 10 computer
What must I do to solve this

Please follow the instructions at the top of the page, and attach the full build output as a text file for us to review.

Thanks, the file attached seems to be the build folder contents, which is not what we need.

Can you perform a build on your project, and then copy the entire text from the Output > Micro Build window, and attach this as a text file?

Thanks for the log, it seems the project is using the old Intellisense System.

Can you try upgrading it as shown on the below page:

Hi,

I followed the steps to install the latest intellisense.
I got the message conversion completed succesfully.
I quit VS2022 and restarted and loaded the project again.
However the problem still remains when selecting the Mega2560 as board.
The Atmega328 keeps selected and not the Mega2560
What to do next?

Do you have an ATMega328 plugged in to your PC, with the vMicro > General > Auto Select a Board/Port When A Device Connects Enabled?

If so please disable the Auto Board selection option and it should then allow the ATMega2560 to stay selected.

Hi Simon,

I have a Mega2560 connected to my PC.
Switching on or off the vMicro > General > Auto Select a Board/Port does not make any difference.
When I remove the comment from #define __AVR_ATmega2560__ see also my first screenshot, it works

If you have the setting disabled, and then select the ATMega2560 board, does the ATMega2560 stay selected?

The ATMega2560 board stays selected, but the code is not highlighted.
See new screenshot attached

Thanks for the update.

Can you send the screenshot including with the Solution Explorer visible, just so we can understand the layout of the project and the library code file showing the error?

Can you also confirm how you navigated to the CPP file where the #define doesn't work?

Hi,

See attached screenshot with the ino file.
By clicking on the tab with the cpp file I get the view like I did sent before, where the atmega2560 code is not activated.

Thanks for the update.  Did you open the CPP file by using the File > Open File Dialogue in VS?

If you click on vMicro > Show/Hide Hidden Files, this will reveal all library sources in the Solution Explorer.  If you close the CPP/H for the library and then re-open them from the Solution Explorer listing the intellisense should be better.

Thank Simon.

That does the job. Now it is working.
I never should have found it this way
Thanks a lot.
