The µVision3 Logic Analyzer provides a graphical display for value changes of variables or VTREGs that you specify.
The Logic Analyzer window contains in the top border several buttons and display fields.
The Setup... dialog defines variables for signal recording and configures the display output. Some configuration settings may be also changed from the context menu that opens with a right click on the signal name.
Export... writes the current recorded signals to a tab-delimited file for analysis with external tools.
The time fields show:
The Zoom buttons define the time range of the display. Zoom All shows the complete content of the signal recording buffer. Zoom Sel changes the display to a selection that you have previously marked with a mouse drag while holding down the Shift key.
Code Show opens the source or disassembly window at the code position that causes the signal transition.
Setup Min/Max configures the display range of a signal. Auto configures the max. / min. values based based on the values from the current recording. Undo restores the previous settings before the Auto button was clicked.
To Logic Analyzer allows you to review change information using the following mouse and cursor commands:
