Timers issue with Atmega328PB

[m4vrick]

Hello everyone,

I'm using Arduino IDE, having a working project on Atmega328P.
I need to switch to Atmega328PB and the same sketch did not compile.

Using Minicore for the board definition, Mozzi version 1.1.2

Here are the errors :

It seems there is some changes in the timers definition for the 328PB compared to 328P.

Do you know any workaround ? 

Also notice I'm using Arduino IDE 1.8.1, when trying to compile this project with Arduino IDE 2.3.2 there is lots of new errors even for the working version.

Thanks for your help, let me know if you need more information.

Not a fix, but somewhere to start... https://onlinedocs.microchip.com/pr/GUID-CBDC1838-0100-4F26-A45A-134958193C3B-en-US-4/index.html
