using EnergyTrace with external target

Hi Jan,

1)
EnergyTrace measures the voltage being provided, so it takes this into account - you can see that it lists the voltage as one of the measurements when you run it. However, please note that for using EnergyTrace stand-alone like you are doing you need to have the tool that is running EnergyTrace also be supplying the voltage to the target device. While the Launchpad can only supply one voltage, if you use the MSP-FET instead, this has a programmable voltage supply capability (and also supports energyTrace). I would recommend getting the MSP-FET tool if you are needing to be able to supply and debug with different voltage levels (it also is a faster tool with more features and has faster EnergyTrace capability if you see www.ti.com/.../slaa603 section 3.5 Limitations, you can see that the MSP-FET EnergyTrace sampling frequency using 4-wire JTAG is 10x faster than the eZ-FET which can only to SBW and at 1kHz).

2)
Since you have CCS v6.1 or greater, you do not need to enter a debug session at all for standalone energyTrace. You can find the steps for launching energytrace without a debug session in the CCSv6.1 user's guide www.ti.com/.../slau157 section 3.3. There's a button for launching energyTrace right from the code editor view.

3)
Yes you should be able to extend the measurement period. In the EnergyTrace window, click on the stopwatch icon - it should have a dropdown with options like 10s, 30s, 1 min, even up to 5 minutes, and finally "On halt" which will run until you click the stop button in energyTrace. Set this interval before you click the start arrow button.

Hope this helps,
Katie
