Messages Window displays various informations and notifications about the compilation process.

It reports for example, time needed for preprocessing, compilation and linking; used RAM and ROM space, generated baud rate with error percentage, etc.
User can filter which notifications will Messages Window display by checking Errors, Warning and Hints box.

In case that errors were encountered during compiling, the compiler will report them and won’t generate a hex file. The Messages Window will display errros at the bottom of the window by default.
The compiler also reports warnings, but these do not affect the output; only errors can interefere with the generation of hex.

Double click the message line in the Message Window to highlight the line where the error was encountered.
