Real-Time Trace lets the user display variables and capture debug messages in dedicated windows from Cortex-M3 target microcontroller hardware. This feature:
- Greatly enhances the debugging capabilites of µVision when connected to the target device.
- Offers the user new approaches for analyzing real-time code running on the target device.
The µVision debugger displays the Trace information it receives from the target device in the following ways:
- Trace Status Bar - a continuous display of Trace output and status messages.
- Logic Analyzer Window - a graphical display of up to 4 global or static variables over time.
- ITM Viewer Window - for viewing debug or other program-specific information from the application running on the target device.
- RTX Event Viewer Window - for viewing RTX Kernel task switching events over time.
Detailed trace infomation may be displayed using the following Trace windows:
- Trace Records Window - a real-time log of processor activity.
- Exception Trace Window - a statistical display of processor exceptions based on trace events.
- Event Counters Window - a resettable count of user-selected events.
The Trace Configuration chapter discusses how to set up the Real-Time Trace displays.
