3.1.2 Power Measurement
The MSP430FR2311 MCU is ultra-low-power and its out-of-box software provides an example of an ultra-low-power application. To measure the applications power we will use EnergyTrace software integrated in Code Composer Studio IDE v6.1 or later.
After importing the out-of-box project into Code Composer Studio IDE and connecting the LaunchPad development kit, follow the instructions below. For more information on how to import a project, see Section 4.1.2.
- Click Debug to program the LaunchPad development kit and start the Debug session.
- Click Proceed on the ULP Advisor to continue to the Debug session.
- Select View → Other → EnergyTrace → EnergyTrace software from the menu bar at the top and then click OK.
- Click the Set measurement duration icon and select "10 sec" from the drop-down menu.
- Remove the following jumpers from the LaunchPad development kit:
J11 at LED2
RXD at J101
TXD at J101
- Select Run → Free Run (Ctrl+F8) from the menu bar at the top.
- When finished, review the power profile of the application and note the battery life of more than 400 days when using a CR2032.
