iSYSTEMTechBlog: Trigger your Trace with any I/O Signal

Do you know how to use any digital or analog signal to trigger your trace?All you need is an iC5000 on-chip debugger with an I/O module!

Connect the signal you like to trigger on to one of the input lines (digital in, analog in) of the I/O module. Configure those lines in winIDEA Hardware/Options/I/O tab.

Next step is to configure an appropriate trace trigger.

• Open the "Analyzer Configuration List".
• Press the "New" "Trace" button.
• Give it desciptive name e.g. "StartTraceOnButtonPress".
• Select the I/O module tab.
• Check the "Trigger".
• Specify the signal to start the trace with.
  • If you use a digital signal, two combinations of digital inputs can be defined - mask 1 and mask 2. The trigger will be generated if either mask1 or mask 2 match. Within a mask, all checked signals must match the high/low configuration.
  • If you use an analog trigger, the trigger is generated if the measured voltage is lower/higher that the specified threshold. 
• To specify the trace content use the "Wizard" button at the bottom or set it manually in the "Trigger" tab.

That's all!
