  1. Hi

     

    I would also love some simple tx/rx code base on which I can expand my research.

     

    I wanted to use this modules in my thesis work but they are way to complicated imho. I then switched to the Nrf24L01+ and never had any regrets about that step. They are way simpler to configure and use.

     

    On the other hand the next step is to build and code a mesh network and maybe the cc2500 are better suited to that task, I am willing to give them a second chance.

    I have enough modules to play with and if there is an expandable code base I am ready to jump in . :)

  2. Hi

     

    I routed a small adapter board for the Olimex Msp 430 Jtag Iso programmer.

    Adapter board:

    The board is based on this schematic:

    Since I don't need all three boards I would give one away for free if someone is interested.

  3. @@Rubi Good stuff. Keep the blog posts coming. Also add a link to your blog in your signature. If you are interested in doing a writeup on the OLED board, PM me.. I can sponsor you one if you are interested.

    Hi

     

    Great I would love to "review" the oled board.

    Thank you!

    Btw. the Ti Msp environment is awsome, great support from Ti , great tools and a great community.

    What else could you wish for,...

     

    Cheers

  4. Hi

     

    I tried first an 10nF and then a 1nF, because I was not sure what the correct capacity is.

    And only after completely removing the cap the programmer recognized the board.

     

    I also verified the caps with an Lcr meter and the smaller one was about 1047pF.

     

    Cheers

  5. Hi RobG

     

    Great booster, I love it.

    I thought solder it together how much time could it take and write a blog entry, what possibly could go wrong.

    Of course I decided the standalone version.

     

    Unfortunately it was impossible to program this little bugger.

    I always became the error message no connection.

     

    After some hours and pretty much desperate, I compared the board to the Powerscope, where the reset circuit is only a resistor, without capacity.

    Then I removed the 1nf cap and the board was programmable.

    Any ideas why ?

    The RC combination is a very usual reset circuit taking care that the processor only comes to live after the circuit power is settled.

     

    Anyhow, after solving this issue the rest was a breeze.

     

    Cheers

  6. Finally I got the code and modules up and running.

     

    Issues:

    Led does not work.

    I found no way to reconfigure and use the cc2500 booster board

    Just changing the pin mapping was not enough

     

    Without debugger I would have had no chance what so ever,...

    Ti supplies a great environment

     

    Once I figured the issues out, I will blog about the solutions.

     

    Cheers

  7. Hi

     

    I get a compile error in   bsp.c

     

    #161 declaration is incompatible with previous "BSP_InitLeds" (declared at line 62 of "C:/Texas Instruments/SimpliciTI-CCS-1.1.1/Components/bsp/boards/LP_G2553/bsp_drivers.c")     /SimpliTi/bsp    line 119, external location: C:\Texas Instruments\SimpliciTI-CCS-1.1.1\Components\bsp\drivers\bsp_leds.h

     

    Any ideas what went wrong ?

     

    Cheers
