I've managed to follow the above guide to integrate the MPU6050 into a system for my Arduino Mega but I can't seem to port it to work with my Uno and I'm a bit lost on why.
I have amended the target hardware and upon compiling for the Uno it throws the following error.
mpu6050_sfcn_wrapper.o ../mpu6050_sfcn_wrapper.cpp
../mpu6050_sfcn_wrapper.cpp: In function 'void mpu6050_sfcn_Outputs_wrapper(real_T*, real_T*, real_T*, const real_T*)':
../mpu6050_sfcn_wrapper.cpp:191:9: error: 'Serial2' was not declared in this scope
Serial2.print("ypr\t");
No problem, revert any mention of Serial2 to Serial and it will now compile for the Uno but I can't view the data in a Scope like I can with the Mega.

Hi Philip Harris,
Simulink external mode uses arduino Serial port 0 to communicate with the target.
In the example, the target is Arduino Mega which has more than one serial port. Serial port 0 is used to communicate with simulink while Serial Port 1 is used to print the logs. But in case of Arduino Uno, there is only one serial port. Changing the Serial Port 2 to Serial Port has no issues on Arduino side, the code will compile and run properly. But, on simulink side, Simulink will receive your debug logs along with external mode communication which might result in some unexpected behaviour.
My recommendation is to comment all lines that use Serial Port 2.
