2.5 Power Tests

Select this option from the main menu to bring up the Power Test submenu. Press S2 to return to the previous menu.

The Power Test menu contains two demonstrations that allow the user to externally measure the current consumption of the MSP430 in both active mode and low-power mode. Current consumption can be measured using a multimeter with current measuring capabilities (ammeter). Remove the jumper on "430 PWR" (JP6) and connect a multimeter in series with the MSP430 VCC supply. This connection can be made using the two large vias near the "430 PWR" text on the PCB. See Section 4 for more details on this connection.

Active Mode: Demo for measuring active mode current of the MSP430. Instructions are presented on screen. Press S1 to continue to the application.

Press S2 to return to the Power Tests submenu.

The Active Mode menu consists of two columns. The left column controls the core voltage (VCORE) of the MSP430F5529, and the right column controls MCLK. The right column displays only those MCLK frequencies that are valid for the current VCORE setting. The capacitive touch pads at the bottom of the board control which column is currently active. The wheel scrolls through the options in the active column.

Press S1 to enter Measurement Mode. While in measurement mode, measure the current by attaching a multimeter across the 430 PWR holes and removing the 430 PWR jumper J6. Replace the 430 PWR jumper after making the measurement, then press S1 or S2 to return to the Active Mode menu.

Press S2 to return to the Power Tests submenu

Low Power Mode: Selecting Low Power Mode takes the user to an information screen with directions on how to navigate the Low Power Mode menu. Press S1 to continue on to the application.

Press S2 to return to the Power Tests submenu.

In the Low Power Mode menu, use the wheel to select a low-power mode option, then press S1 to enter low-power mode. While in low-power mode, measure the current by attaching a multimeter across the 430 PWR holes and removing the 430 PWR jumper.

Press S1 or S2 to return to the Low Power Mode menu.
