Using Visual Studio Code as alternative for Arduino IDE - Setting register bit fails - visual-studio-code

Question

Update #1
The code is working now.
Try putting those four assignments (TCCR1 to TIMSK1) inside a routine, and call it from setup. It's strange to see them treated as global variables; they aren't really. – aMike
You were right. After putting it in a routine I am able to verify and upload the code in VS Code. The result is as expected.
After the code works now I tried to improve the style of the code, so I did a little research how to make it easier to read. So it looks a bit different now.
Not that this has anything to do with your problem, but you probably don't want the semicolon in #define PRESCALE_OFFSET 3035; Also, like aMike said.
Thanks for the advice.
Although it works, VS Code still marks the relevant position as not defined as lurker mentioned. But that is how I have to do as far as I know. For example: Arduino - Port Manipulation
Thanks for your replies!

ISSUE
I am working on a small embedded project and I want to use an Arduino Uno for realization.
I don't like the Arduino IDE and want to use Visual Studio Code instead.
I managed to get everything running so far. I can compile and upload the code to the Board to get some output on the serial monitor for example.
So far so good.
Now I want to dive deeper and set some register bits to set up a timer interrupt. This code below throws an error in VS Code during verfication, but not in Arduino IDE. I uploaded via Arduino IDE and the code runs as expected.
Does anyone know how to overcome this issue in VS Code?
I am a beginner, so please don't wonder about the structre and the actual content of the code. At the moment I am trying to figure out how to use header files correctly and how to set up a useful structure.
Thanks in advance!
