MSP430FR2633: MSP-CAPT-FR2633: CAPTIVATE_PHONE sample code to show 5uA as 'ILPM3, CapTIvate, 1 proximity, wake on touch'

Part Number: MSP430FR2633
Other Parts Discussed in Thread: ENERGYTRACE

Hello,

I need to show a low power operation with the PHONE board. Could you please advise ?

- The CAPTIVATE_PHONE sample project as-is, its current consumption was 725 uA on EnergyTrace.

- 'Wake on proximity' was set on the EVSW 'CapTIvate design center'. Then the current reduced to 275uA.


And could you please advice the remaining action items ?

I think one of the items would be a function or a parameter to disable all the mutual electrodes.

    Hello Hideaki,

    If you are getting into the 100s of uA, then this tells me you are not going to sleep at all. If you want to test i button wake on touch, then the best way to do that is to reprogram the device to the out of box experience demo code. You can then open this up in the CapTIvate design center to chose which button is wake on touch. The BSWP board is the easiest to see this.

    In the CapTIvate Technology Guide -> Workshop (Getting Started) - > Experiments with Low Power also walks you through setting up the kit with the lowest power. software-dl.ti.com/.../ch_workshop.html

    Please also see the CapTIvate Technology Guide - > Design Guide -> Ultra Low Power for more low power CapTIvate informaiton as well.

    Jace,

    The BSWP board is no problem.

    The goal of my customer is the mutual board like the PHONE operates @ 5uA as 'ILPM3, CapTIvate, 1 proximity, wake on touch'.

    When the PHONE sample code was programmed and executed, I found that the menu "Wake On Proximity Sensor" was "None" on the EVSW. It was the first step to the 5uA.

    Next step would be disabling the mutual electrodes before calling CAPT_appSleep() , but I could not find my answer from the 'MSP430™ CapTIvate Library API Guide' at [C:\ti\msp\CapTIvateDesignCenter_1.30.10.00\CapTIvateDesignCenter\docs\api_guide\FR2633\html], so I'm asking your help.

    Hideaki,

    I would modify the Design Center file schematic view so it only has the wheelButtonSensor. This way, the other buttons no the Phone baord are not on ever and you can get a quick current measurement.

    Jace,
    I appreciate your response. It seems easy for me.
