USING THE C3X DSK DEBUGGER ON THE PC
The C31 DSK Debugger is only available on select PCs in the DSP Lab because the program will only be loaded when a C31 DSP board is detected. The debugger window consists of 4 panes as shown in the figure below.


The top left pane is the DISASSEMBLY pane. It displays the assembler program. If the source program is written in C, this screen will display the compiled C program in assembler format.

The top right pane is the CPU REGISTERS pane. It displays the contents of the registers, interrupts, program counter, stack pointer, etc. It is usually displayed in 40-bit hex. To display the contents in floating-point format, press the F3 key. Pressing the F2 key will revert this display to hexadecimal format.

The COMMAND pane is located on the bottom left and allows the user to enter commands in the debugger.

The MEMORY pane is the bottom right pane and displays the content of the memory locations indicated by the address on the left. The content is also displayed in 40-bit hex format.

USING THE DEBUGGER:

• To activate the debugger program, click on Start->Programs->DSP Lab Tools->C31 DSK Debugger.
  
  
• Before loading a program, it is always a good practice to first reset the debugger with the reset command.
  
  
• To load a program, type load filename.out or load filename.dsk at the CMD prompt in the COMMAND pane.
• You can now either step through the program using function key F8 or run the entire program by pressing function key F5. If you are running the entire program, you would need to halt the program first before you can view any changes to the data stored in memory. Pressing Enter would halt the running program.
• To quit the debugger, type quit at the CMD prompt in the COMMAND pane.

ADDITIONAL FEATURES:

• The debugger also allows assembling of stand-alone assembler files in the COMMAND pane by typing dsk3a filename.asm at the CMD prompt.

The most commonly used commands can be found in our reference guide for the simulator and debugger.
