Here is what chatGPT said: The errors you're seeing suggest that the selected processor doesn't support certain ARM-specific instructions. These errors are usually associated with the settings you've chosen for the...

I opened an issue on their github.

Yep, that’s correct.

This exact thing happens to me and the Teensy 4 when I compiled my code and it produced code that (I think) was too big for the teensy. When not uploading and just building, the compiler says space free for local...

Well I know what the parameters do and I see what works with the signals I have. I have an intuitive understanding of what happens when I adjust the values and I’ve done that by experimenting a lot. However I don’t...

Virtual methods were mostly for convenience to use less code. I’ve removed the virtual methods and I’m using the curiously recurring template pattern in stead. Works the same but at compile time (according to chatGPT)....

That would not be applicable for my program. I use many instances of it everywhere in my program and one instance is meant to work with one sensor.

My filter class does not have this problem. I know using a .h file is not the problem. I'm allocating statically and it works as long as the constructor and the AddValue method in this class are either in a .cpp file...

Forgot to mention that I’m using PlatformIO with VScode.

I see. It could be the inheritance from the base filter.

I didn’t measure that precisely, I seem to have saved a microsecond or so for a bunch of these filters after moving it into .h file and removing the virtual functions. I think the compiler inlines it anyway as long as...

I've done some experimenting and consulted with chatGPT about possible performance gains. Polymorphism is bad so I changed to compiletime polymorphism by using templates. Also some other stuff like using in stead of...

Thanks for the suggestion Paul. It depends, I have 10 sensors and this way I can do the calculation on two sensors at a time while waiting for the next two sensors to be read by the ADC so I think this is faster,...
