  22. 22. 3. Debug your code ! • Perform a real time run :  Debug  Run (F5) Note 1: the bottom left corner will be marked as : “DSP Running”. You’ll see no activity on the peripherals of the Adapter Board because our first example program does not use any of them ! Note 2: the yellow arrow is no longer visible – that’s another sign of a real time run. • Stop the real time run :  Debug  Halt • Reset the DSP : Debug  Reset CPU Debug  Restart • Run again to main :  Debug Go MainTechnology beyond the Dreams™ Copyright © 2006 Pantech Solutions Pvt
  23. 23. 4. Watch your variables • Open the Watch Window :  View  Watch Window • The variable ‘i’ is already visible inside the “Watch Locals”-window . • To see also the global ‘k’ we need to add this variable manually. This can be done inside window ‘Watch 1’. In the column ‘name’ we just enter ‘k’ and in the second line ‘i’. – Note : another convenient way is to mark the variables inside the source code with the right mouse button and then select “Add to watch window” • note : with the column ‘radix’ one can adjust the data format between decimal, hexadecimal, binary etc.Technology beyond the Dreams™ Copyright © 2006 Pantech Solutions Pvt

  27. 27. 6. Adding a Breakpoint • Set a Breakpoint : – Place the Cursor in Lab1.c on line : k = i * i; – Click right mouse and select ‘Toggle Breakpoint’ – the line is marked with a red dot ( = active breakpoint ) Note : most Code Composer Studio Commands are also available through buttons or trough Command -Keys ( see manual, or help ) • Reset the Program  Debug  Reset CPU  Debug  Restart • Perform a real time run  Debug  Run ( or F5) • DSP stops when reaching an active breakpoint • Repeat ‘Run’ and watch your variables • Remove the breakpoint ( Toggle again) when you’re done.Technology beyond the Dreams™ Copyright © 2006 Pantech Solutions Pvt

  29. 29. 7. Set a Probe Point • Causes an update of a particular window at a specific point in your program. • When a window is created it is updated at every breakpoint. However, you can change this so the window is updated only when the program reaches the connected Probe Point. When the window is updated, execution of the program is continued. • To set a Probe - Point : – Click right mouse on the line ‘k = i*i;’ in the program first.c – select : ‘Toggle Probe Point ‘ ( indicated by a blue dot ) – select  Debug  Probe Points... – In the Probe Point Window click on the line ‘first.c line 13 -> no Connection’ – in the ‘Connect to’ - selector select ‘Watch Window’ – exit this dialog with the ‘Replace’ and ‘OK’ – Button • Run the program and verify that the watch window is updated continuously.Technology beyond the Dreams™ Copyright © 2006 Pantech Solutions Pvt

  34. 34. 9. GEL - General Extension Language • language similar to C • lets you create functions to extend Code Composers features • to create GEL functions use the GEL grammar • load GEL-files into Code Composer • With GEL, you can: – access actual/simulated target memory locations – add options to Code Composer’s GEL menu • GEL is useful for automated testing and user workspace adjustment . • GEL - files are ASCII with extension *.gelTechnology beyond the Dreams™ Copyright © 2006 Pantech Solutions Pvt
