BOOSTXL-TLV8544PIR: Creating a Wireless PIR Motion Sensor Using CC2650 Launchpad

Part Number: BOOSTXL-TLV8544PIR
Other Parts Discussed in Thread: CC2650, TLV8544

I have a CC2650 Launchpad + BOOSTXL-TLV8544PIR and I am trying to get the two boards to transmit the PIR sensor data wirelessly. In the BOOSTXL-TLV8544PIR User's Guide it states: "this board design could easily be used as the basis for an ultra-low power, battery-operated, wireless PIR or microwave motion sensing system, further simplifying design and speeding time to market." Is there a document that explains how this is done? I found a few TI Designs that seem to use similar hardware and already have firmware (TIDA00759 and TIDA01398). Is there a simple way to flash this firmware to the CC2650 Launchpad and use it with the BOOSTXL-TLV8544PIR?

Thanks,

Matt

    Hello Matt,

    While the CC2650 LaunchPad was used as the controller for the demonstration GUI, the CC2650 RF functionality was not utilized.

    I am not aware of any firmware with wireless functionality for the TLV8544PIR. The intent was to demonstrate the nano-power and PIR functionality of the TLV8544 operating with a wireless processor. Adding the actual wireless would add too much complexity for us "simple" op-amp guys. :^)

    Sorry.. But it is USB based only at this time.

    The firmware is fairly simple. It reads the internal and I2C ADC's and two GPIO pins and continuously streams out the data via the emulated USB COM-xx serial port (115.2k) as four comma separated ASCII values. This could also be done via Bluetooth. A nice "rainy day" project.

    Hi Paul,

    Thanks for the info. I am also one of the "simple" op-amp guys and was trying to avoid the complexity if I could.

    Do you know if the firmware is available in something more accessible than the .OUT file so I can try to make the changes to send via Bluetooth? Is there somewhere I can find the actual source code?

    Thanks,
    Matt

    Hi Paul,

    I am wondering if the source code for the firmware is available somewhere? So far I have only been able to find the .OUT file.

    Thanks,

    Matt
