Programming CC1111 USB Dongles...

Other Parts Discussed in Thread: SIMPLICITI

Please pardon me if I come across as a noob.

I want to implement 2 chat client nodes using CC1111 USB Dongles operating at 433 Mhz.

For that I plan to purchase 2 sets of Chronos watches and use the USB Dongles that are provided with the Kits.

At first, I will implement the Chat Application using bundled stack "Simpliciti".

I want to know if I am able to modify the software on the C1111 USB Dongles. I want to use the OpenTag software stack on the USB Dongle for experiment.

I believe I need to purchase the CC Debugger pod also.

Any comments on:

i) My shopping list

ii) Whether the Software Stack can be replaced?

iii) Experiences you've had with this equipment.

iii) How easy/ difficult will it be to port the OpenTag software?

Please help me....the more I dig, the more I am confused...

    i) the shopping list seems pretty complete.

    ii) Yes, you can modify the software stack.  The version supplied with the Chronos watch is a bit hidden as it was compiled into a library object and then linked in with additional code to implement the watch functionality.  You can always download the latest version of SimpliciTI directly and work with it.  There are sample applications in the SimpliciTI code drop which will work on the dongles.

    iii) My experience is mainly with the SimpliciTI stack itself.  However, the Chronos watch demo works quite well and you should be able to modify the projects directly to add functionality.

    iiii) Since I'm not familiar with the OpenTag software, I cannot comment on the ease of porting it.

    You may want to look at DN117 (http://focus.ti.com/analog/docs/litabsmultiplefilelist.tsp?literatureNumber=swra306&docCategoryId=1&familyId=367) for some UART example code to work with SimpliciTI.  This may help you get started with your chat application.

    Thank you, Jim.

    :-) Any information related to this is useful for me.

    I have read somewhere the C1111 dongle has 8K Flash, and Opentag requires more than that. (~32K) 

    I will confirm this and update this post whether we were really able to use C1111 USB dongle or not for the benefit of others.

    Thanks again,

    Amit

    I'm not sure which part is shipped on the dongle but the CC1111 comes in 8/16/32 kB flash configurations so if you have the ability to replace the one on the dongle (if it is not a 32kB device), then you should be able to work with it.
