MSP-CAPT-FR2633: Using The CAPTIVATE-PROXIMITY Board

Part Number: MSP-CAPT-FR2633

I have an older eval kit of the MSP-CAPT-FR2633 that came with the CAPTIVATE-PROMITY Rev B board. I could not find any example files for it, and upon further research I found it was discontinued.

If possible I would still like to use it for some basic functions for testing: Left zone enables a GPIO. Right zone enables a different GPIO. Center zone disabled. The hand motions across the left or right zone will alternate enabling/disabling their respective GPIOs, so that I can power cycle external circuits.

I tried setting up in the Captivate Design Center the Proximity sensor, but the element count only allows for 1, I cannot select 2 (for the left/right zones). Am I doing this right?

  • Hi Thomas,

    Are you trying to sense only proximity or proximity gestures?

    Hi Leo,

    Only trying to sense proximity. And turn down the sensitivity to 2 cm instead of the default 10 cm.

    Thanks,

    Hi Tom,

    The attached zip includes the example project which runs the sensors + the gesturing and LEDS.

    It also contains the CapTIvate Design Center project file.

    The version of the CapTIvate Design Center project *.ser was created in an earlier version.

    You can still open it in the latest version of design center but will probably see a warning to rebuild with the newer version.

    You should copy the RX/TX assignments (take a snippet) and re-create with same RX/TX assignments.

    Once you rebuild it should talk with your PCB.

    Hi Leo,

    I took the example project and remade with latest version, it worked. I then turned the sensitivity down so physically pressing the PCB will count as a touch, instead of the original example where hovering your hand about 10cm up counted as a touch.

    Now I just need to have in code for two separate GPIOs to enable high/low when I touch the left or right zones (I want to power cycle two external circuits with each touch as on/off). I'm a hardware guy, so I'm a little slow to figure things these things out in software. Any help you can provide on this would be much appreciated.

    Thanks,

    Tom

    Hi Tom,

    I recommend you look at this example in resource explorer:
