'Serial1' was not declared in this scope - ????

Projects Programming

I have previously compiled my code using the Serial1 commands for my Arduino Micro and the code also uploaded and works. But I made some programming changes, clicked on verify/compile, and I keep getting an error now, 'Serial1" was not declared in this scope.

I opened my previous program version that compiled and continues to run on my Micro and it also results in this compiler error. What am I doing wrong?

Thanks,

Dean

look at the rest of the error message you will see a line number that tells where the error is. It may be that theres a missing ; or } before the use of serial1.

If you can not find it post the program so we can find it for you

Maybe you selected accidentally a different board type.
Please make shure that the Micro is still selected.
