Hello!

First of all i want to mention that i am not an expert in this watch. i only want to click a button and make it send a signal to an arduino or something. can someone please help me write the code? or at least guide me?

Thanks a lot!

    What processor is on your board?

    What MSP430 Derivative are you using?

    Im not sure I understand what you mean. I have the ez430-915 watch. i downloaded CCS and IAD workbench

    please bear with me

    RND,

     

    Not a problem. We're here to help. Now that we know what you're using we can be more helpful. The ez4390915 Chronos Watch has inside the CC4306137 Chip. You can find a lot of information about it here:

    http://processors.wiki.ti.com/index.php/EZ430-Chronos?DCMP=Chronos&HQS=Other+OT+chronoswiki

    http://focus.ti.com/docs/prod/folders/print/cc430f6137.html

     

    You want to communicate with an arduino? or something? You can communicate with any other device that has a CC1101 or similar radio since that's what the CC430 has. There are many ways to do so. You could connect a CC1101 or CC430 to the Arduino. As far as sending the data, it's just a matter of sending the button press to the other side and using it. The demo code of the watch does that I believe.

    Yes, an arduino. 

    Will this work? http://www.newark.com/texas-instruments/cc1101rtk/ic-rf-txrx-300mhz-to-928mhz-qfn/dp/50M8833?CMP=AFC-JY6146109556

    also, could you please point me to the demo code you mentioned? I was trying to find it but I couldn't

    Appreciate it

    Yes, that would work but that's only the IC. You still need a crystal and passives to operate it. I recommend getting a ready to go module. Why go to the hassle of making a PCB?

    The wiki link that I sent you has the following list of compatible RF boards.

    • AMB8423 eZ430 868/915MHZ target board based on CC1101 and MSP430F2274
    • EM430F6137RF900 CC430 Wireless Development Board
    • CC1111EMK868-915 CC1111 868/915 MHz Evaluation Module. This is similar to the USB Chronos Access Point except for minor differences in the schematic. It also includes additional headers and for reprogramming using the CC Debugger.
    • CC1110DK-MINI-868 CC1110 Mini Development kit

    Any of these would work. Note that some actually contain an MSP430 as well, so Arduino would interface to the MSP430. In that case, unless you 100% need an arduino, why not just go with MSP430 since you'll have it already?

    The CC1101EMK boards are "bare" in that all they contain are the radios. You can connect wires to the Arduino or design a PCB with the RF1 and RF2 connectors.

    Thanks a lot!

    I'll look into it and if I have any questions I'll be back :)
