I am trying to modify a library I created to be able to use with Arduino UNO R4 Wifi.
The code below compiles with no issue in IDE v2.3.2 if I select to compile for a Mega, but if I select UNO R4 Wifi as board I am getting this following error:
C:\Users\sherz\AppData\Local\Temp\arduino\sketches\800F4B443EAAA27A181C00ED62FB9F67\sketch\LIN_ReadWrite.ino.cpp.o: In function

collect2.exe: error: ld returned 1 exit statusUsing library LIN-v.14 in folder: C:\Users\sherz\OneDrive\Documents\Arduino\libraries\LIN-v.14 (legacy)

Any suggestions how to resolve this?

Probably in the process of modifying it.
