message queue
Posted: Thu Aug 20, 2009 8:29 amI have the pro edition. I'm trying to use message queues without success in compiling the project.
Here is a try based of the tut5
I'm working with MPLAB (build 8.33), Compiler C-30 (build 3.12). salvo (build 4.2.2) library: C:PumpkinSalvoLibMCC30-v3libsalvolmcc30it,
I marked the changes that I have done with green color. I'm trying to do the same in my project, working with source file not library, facing the same error.
Please Advice,
Michael David.
