Thank you for looking this. I don’t know if this is a problem anyone else has encountered, or whether I’ve done something wrong. I am looking for advice, so…
First I will give an overview of the problem, along with the hardware and software used to compile my Arduino Sketch, then I will provide the details (the error messages on compile and the code from the header files where the problem occurs and the Arduino sketch). Afterward, I’ll provide my tentative Ideas for what is wrong, though I don’t know how to solve the problem.
OVERVIEW:
This sketch COMPILES for the Arduino UNO R4 Minima using the following hardware/software:
Mac mini (M1) with OS 13 or 14 (I’m not near that computer now, so I can’t )
Arduino IDE 2.X (I uploaded it in late November 2023)
It DOES NOT COMPILE with my new system when I compile for the Arduino UNO R4 Minima using the following:.
MacBook (M3) with OS 14.5
Arduino IDE 2.3.2. I compile the same sketch for the UNO R4 Mini. It DOES NOT COMPILE.
However, with the MacBook with the same IDE and sketch DOES COMPILE when compiled for the Arduino UNO (R3).
DETAILS:
____ Error info - Below are the errors thrown when compiled and the code from the library .h and .cpp files and the Arduino sketch.

TENTATIVE CONCLUSION/HYPOTHESIS:
There is a difference in the environment of the M1 mini and the M3 MacBook. That difference might involve one or more of the following:
-
the Mac OS - though this I should note that the same issue is true on my old MacBook Air using IDE 1.8 (compiles for R3, but not R4).
-
the Arduino IDE
-
the internal (to the IDE) R4 board definition that is currently available (renesas_uno/1.2.0?) vs. the one I last used in May at home. Version
-
the internal SPI definition that is currently available vs. the one I last used in May at home.
-
something I haven’t thought of
Does anyone know what I’ve done wrong, or can do differently, or who has had this problem?
Thanks for any thoughts you might have.
