Can't find the Wire.h library
Feb 4th, 2023 at 10:10am
Print Post  
Hi,
I used to use the free version of Visual Micro before and every thing seemed OK to me. I didn't remember any troubles using it. Just installed the extension on Visual Studio and Arduino IDE and coded. But now, I have just purchased the commercial version and tried to use it. But somethings unusual happens:  Visual Micro can't find the Wire.h library even though  Arduino IDE finds it and compiles the sketch well.
I use Arduino IDE 2.0.3 and Atmega 2560 board. 
Could you please help me to solve my issue?

My sketch is included below

Thank you

Hi Sir,
I am trying to use vMicro for compiling my Arduino sketch which is built and ran without any bug in Arduino IDE installed in the same laptop but it seems that VS2022 can not recognize the paths for the IDE and libraries. Please help me for solving this issue.
Included here is the output text file.

Thank you and best regards,
Tuan Tran

It is not clear where you see the problem. The build output shows good build.

Please explain what issue you see?

Hi Sir,
As I mentioned before, the complier can not find the libraries while Arduino IDE can, so there are 68 errors in the list included below.
The fist line is: cannot open source file "Adafruit_ADS1X15.h"      means that the library folder is not recognized      
So how can the compiler built the sketch?
Regards

The build output you provided shows that compile is OK

Code
Select All
Program 1015DiffContinuous size: 10210 bytes (used 4% of a 253952 byte maximum) (7.90 secs)
Minimum Memory Usage: 1705 bytes (21% of a 8192 byte maximum)

The errors you see must be related to intellisense. The "build" and "intellisense" systems are not related. As an example, switch the Combobox after the errors list to "Build Only", then you will understand the difference.

The intellisense should not show these errors. Is this an old project? Please show screen shot of solution explorer.

Hi Sir,
After I opened some Arduino sketches, the Intellisense errors disappeared in Error List. I do not know why. Everything seem to be OK now. Thank you for helping me promptly.

Can I use the debug function with Arduino on this environment?
If yes, do I need to do any configuring?

Thank you and best regards,

Tuan Tran

Glad everything is working as expected now. You do have to click build one time for a project to make intellisense accurate. That allows Visual Micro to discover underlying source codes from the compiler results.

The options for debugging the ATMega 2560 are to either use our unique Serial Debugger:

Or a 3rd Party GDBStub which gives limited Hardware Debugging capability via the Serial Port:
