CP316: Microprocessor Systems and Interfacing

Introduction to the Development Environment (part 1)

PostLab

1. In your lab notebook, summarize the steps required to create a project in the MPLABX IDE.
   
   
2. Work through sections 3.5 Using MPLAB IDE and 3.6 Using the MPLAB SIM in Debugging PIC18 Applications from the text book [Chapter 3; pdf, 36pp, sample chapter from text web site].
   
   Things to note:
   • Here is a correction:

     3.6.6 Tracing Code
     
     The text says to go to Debugger/Settings to enable tracing. This no 
     longer exists in MPLAB X.
     
     To enable tracing:
     
     go to File / Project Properties
     click Simulator from the left tree
     choose Trace from the Options categories dropdown
     set Data Collection Selection to Instruction Trace
     click Apply, then OK
     go to Window / Debugging / Trace
     run debugger
     

   • The example uses an older version of the IDE so some of the screen shots will not be identical.
   • The program is poorly written. If the problem is not obvious, put a breakpoint at the last nop and then single step through the code. What is the problem?
   • Huang doesn't use the project wizard when creating projects.
   • Huang introduces some additional debugging techniques.
     
     
3. In your lab notebook, list the specific debugging techniques (e.g. breakpoints) covered in the lab and postlab exercises with a brief description of the technique.

Your lab notebook will be checked for the post lab work at the next lab.
