CCS/MSP-EXP430FR5969: How to use EnergyTrace with external power?

Part Number: MSP-EXP430FR5969
Other Parts Discussed in Thread: ENERGYTRACE

Tool/software: Code Composer Studio

I want to trace the energy/power using EnergyTrace. Instead of powering the Launchpad (MSP-EXP430FR5969) through USB, I want to power it using external power at J1 (Vcc, GND). Is it possible? If yes, how can I do that?

  • Hi Nawaz,
    If you want to use the EnergyTrace, you have to use the USB to power up the board. On the ez-FET part on the Launchpad, it have a measurement circuit which work with the EnergyTrace. The external power will go bypass this circuit, so that you can not use the EnergyTrace.

    Best regards,
    Cash Hao
