Can anyone please help. Transition from R3 to R4 was meant to be dead easy but it is turning out to be anything but.
I can't get any sketch with wire.h to compile. I have read several posts with a similar problem and the answer seems to have been that the compiler is picking up some old version of wire but if that is the case here I can't find it. I have scanned my machine end to end and can only find two versions of wire. One in the avr/1.8.6 package and the other in the renesas_uno/1.2.1 package. Presumably that is how it should be.
Running the compiler in verbose mode the first few lines (clipped) are as follows :-
FQBN: arduino:renesas_uno:unor4wifi

Looks OK to me? Ideas anyone?

And the last compilation line is :-
Using library Wire in folder: C:\Users\Rob\AppData\Local\Arduino15\packages\arduino\hardware\renesas_uno\1.2.1\libraries\Wire (legacy)
Please post a small but complete sketch that illustrates the problem, together with the full error report copied from the IDE. Please use code tags when you post the sketch and report

Here we go. Code . . . .
#include<Wire.h>
const int MPU = 0x68;
void setup() {
Wire.begin(); //Initialize
Wire.beginTransmission(MPU); //Start communication
Wire.write(0x6B); //Talk to the register 6B
Wire.write(0); //Make the reset (place a 0 into the 6B register)
Wire.endTransmission(true); //End the transmission
Serial.begin(115200);
Serial.println("Done");
}
void loop() {
}
Is there any way to get the IDE errors to insert correctly? Or at least not line wrap in this editor

Here is the full IDE error output. Sorry about the way it looks but if you can explain how to make it look better I will gladly re-post.

Compilation error: no matching function for call to 'beginTransmission(MPU_Type*)'
In your initial message, you didn't show any kind of error, let alone a compilation error. What were we to do with that?
In the sketch you just posted, yes, there is an error, but it's clearly spelled out what's causing it. MPU is already used in the R4 core code. Simply rename your constant to something else (even myMPU) and the sketch compiles.
Quite often, trying to use short, all capital names is a recipe for trouble, as the core predefines a multitude of them and you never know when you will collide with them.

That simple! OK - thank you very much indeed. Greatly appreciated.
Code tags is the best that you can do for error messages. For sketches it is a good idea to use Auto Format in the IDE before posting them if you don't already use it as a matter of course
It seems like @van_der_decken has nailed your problem
