identifier "Serial" is undefined with version 0.4.0

[lozziboy]

This is to open again the same issue discussed here
#866
and there
#808

IntelliSense has still some problem in finding the following keywords
"Serial"
"TCCR2A"
"TCCR2B"
"OCIE0A"

To manually solve this, I added the following defines to c_cpp_properties.json:
"USBCON", "__AVR_ATmega328P__"

to do this is required to disable Intelli Sense Auto Gen from the vscode extension settings

This is odd, I tested this with the uno and it was working before we released.

I'm able to repro this on my Machine now, looking into what changed.

Hi guys,
I can confirm the same issue on a WIN10 machine.

[adiazulay]

so it looks like removing the "-MMD" complier arg from c_cpp_properties.json is culprit. We removed it because it was creating file erroneously on mac and linux.

Will revert to including it in the next release

And we were like "What could possibly go wrong?" Good find! Maybe we can find another solution for the null.d-problem then.

#1231 forces USBCON to be included in all config files.

This should be fixed in v0.4.1 do you mind giving it a try and letting me know if it works?

Awesome, workes like a charm for me now with v0.4.1. It added the "USBCON".

Hoping this update will ship soon!

0.4.1.rc1 works fine for me: USBCON is automatically added to c_cpp_properties.json
The Serial (not defined) issue is solved.
Thank You very much :)

Unfortunately the problem is still partially present.

Updated to 0.4.1-rc1

Still having problems with other keywords

To workaround this, I added the following define to c_cpp_properties.json:
"__AVR_ATmega328P__"

PS: as usual, to do that, is required to disable Intelli Sense Auto Gen from the vscode extension settings

Thank you so much for the screenshot! Now I realize why we didn't see this during testing, we only ever tried using the Arduino API, not the chip registers. Can you check whether the -MMD flag is added to the compiler options by the auto generation?

Where can I check it?
