Command Window

The Command Window shows generic debug output information and allows entering debug commands and debug functions to interact with the µVision Debugger.

Output Window — Command

Use expressions to view and modify the value of variables, or registers, or memory locations. For example, type the following commands:

Command	Effect
R7 = 12	Assign the value 12 to register R7.
CPSR	Display the CPSR register.
time.hour	Displays the member hour of the time structure.
time.hour++	Increments the member hour of the time structure.
index = 0	Assigns the value 0 to index.

Invoke debug functions by entering the function name along with the function arguments. For example:

Mix_Sine (300,2000)             // your debug function
