SimpliciTI version 1.2.0 -- Available now!

Other Parts Discussed in Thread: SIMPLICITI, CC110L, CC1120, MSP430F5438, CC1121, CC1101

SimpliciTI version 1.2.0 is available now at www.ti.com/simpliciti.

 The major driving force behind this version includes support for Frequency Hopping Spread Spectrum (FHSS) development.  FHSS is supported via a new network application PLL (nwk_pll) which, when enabled, manages a coherent clock system across the entire network.  Utilizing this allows for generating a coherent channel changing schedule required for implementation of FHSS systems.

Additionally, a UART Bridge sample application has been added.  This application shows a simple wireless UART interface between two RS232 interfaces.  Included with this project is a simple UART driver for use on both the 8051 and MSP430 systems.  This driver is identical to the one in design note DN117 with added support for additional radios and MCU's.

 All sample application projects have been expanded to support the full set of radios capable on each platform.  This should speed the process of starting development for projects which can be based on one of the samples.

 Several bug fixes have been implemented.  Most notably would be the addition of a time out mechanism in the transmit while loops.  This eliminates the occasional hang seen during transmit operations.  See the release notes included with the distribution

 

 SimpliciTI Road Map; items in progress...

  • Support for the CCS compiler.  Release 1.2.0 currently only supports the IAR compiler.
  • Support for the CC1120 and CC110L radios.
  • Projects for the MSP430F5438 experimenters board and the new SmartRF TrxEB board.
  • Support 32kHz oscillator with the nwk_pll application

    Hi Jim,

    The link to download the 1.2.0 version seems to be broken. I end up at a "Sorry, we couldn't find your page" page.

    Thanks,

    Barry

    Of course it is!  Grrrr...  Nothing is ever easy, right?  I'll look into it and get back to you.

    When do you expect the CCS version to be available? And does the IAR version support cc430?

  • in reply to Timothy Barr
    TI__Genius 14940 points

    We are working to get the CCS version out as soon as possible.  I don't have a hard date but we are shooting for mid first quarter 2012.

    Yes, the IAR version supports the CC430.

    Did you manage to resolve the issue with regard to downloading the latest simpliciti.. i.e the link is broken or unavailable

    Unfortunately the people needed to correct the problem are already on vacation for the US Thanksgiving holiday and won't be back until Monday.

    I thought about removing the post but then everyone who was notified of the original would not find it but leaving it seems a little like teasing the community.  Either way leaves something to be desired.

    My apologies for any inconvienence,

    Hello 

     

     I am  a student.

    And currently i am working on a project based on ez430 Chronos watch.

    I wanted to know that using SimpliciTI  Rf Protocol a packet of how many bytes  can i transfer at a time?

    I have observed that Chronos control center sends packets of 3/4/7/22/24 byte depending upon various functions used.

    I am not an Electronics Engineering student so i have almost nill knowledge on rf communication.

    Please help me.

    Thank you

    Hi Manan,

    Im no Moderator here but please create a new thread if you have an offtopic question. This is not the appropriate thread for asking general Simpliciti questions.

    Anyways the maximum number of bytes that you add as payload to a packet are defined by MAX_APP_PAYLOAD in the smpl_nwk_config.dat file. All messages that got a longer payload than that are just discarded and not sent. So this is the limit for your messages. SimpliciTi itself is limited to the size of the Radio FIFO which is 64 bytes for the whole packet(incl. address,length and so on). It is limited to this size because imho it expects a complete packet by the RX ISR and cannot handle split packets, same applies for TX.

    The hardware itself is limited to packets of up to 255 bytes.

    Yes, it is still broken.  I'm still working the issue.  I'll post as soon as it is corrected.

    The download link for IAR SimpliciTI does not seem to be working.  Can you send me the file directly?

  • in reply to Jonathan9420
    TI__Genius 14940 points

    As much as I would like to provide an ftp drop for this package, I am bound by some minor legalities which preclude me from doing so.

    There are peoople still working on getting the link fixed.  As simple as it that task seems to be, it has yet to be achieved.

    That makes it all the more frustrating for the rest of us that have been waiting almost 2 weeks since the announcement that the download was available :-)

    All,

    The link appears to now be working.

    I apologize to all for the inconvenience and appreciate your patience through this process.

    Hi Jim,

    When do you expect to have a release of the stack with support for the cc1121?

    I am currently using V1.1.1 of the simplicti stack with the  cc1101 and would like to migrate the stack to use the cc1121 hence the reason I ask the question.

    would you have any info that might be helpful for this migration?

     

    Kind regards

    What's the ETA on SimpliciTi 1.2.0 for CCS?

    Thanks,

    I cannot compile one of the examples distributed with simplicit 1.2.0 on IAR kickstart : it says too much object cod produced..

    Is this a problem of settings of procedure or just couldn't be done.

    Regards,

    Robert.

    HI,

    The free version of IAR only allows you to compile programs that generate 4K or 8K of object code (depending on which processor you are using).  You can look into upgrading to a full version of IAR. That's what we did, but it is on the pricey side. CCS is also another option. I believe they allow up to 16K in the free version. Their full version significantly cheaper.

    HTH,

    Hi,

    thanks for response. I agree that buying full version is a cure. But what bothers me that I have a project in IAR based on Simpliciti 1.1.1 and can be compiled without any problems (but on IAR 4.21.8) ...

    I believe that version 1.2.0 is not much bigger that 1.1.1 - or am I wrong?

    Regards,

    Robert.

  • in reply to Bulek
    Genius 3020 points

    Hi Robert,

    Perhaps look at the map file from your 1.1.1 project and see how big the code is.  Maybe it's just barely under the limit and simplciTI 1.2.0 has pushed it over.  Any differences in the optimization settings?

    BR,

    Barry

    Is there any update on the release date for the CCS version of simpliciTI 1.2.0?

  • in reply to Ian Barnes68507
    Prodigy 65 points

    As discussed in the first post of this thread, that SimpliciTI support to CC1120 is in progress on Nov,2011.

    So, is this support ready now  ?

    If not, when it is expected to ?

    I had some problems downloading the v1.2.0 in Chrome. 

    Clicking the Download & Register button didn't do anything, and no output in the javascript console.

    I ended up extracting the URL from the html, I'll provide it here for simplicity:

    So... the year is 2014 and i was wondering when will you release simpiciti 1.2 for CCS.

    Or support Tiva C series... really looks like abandon-ware at the moment.

    I've downloaded the IAR version and if I remember correctly I could compile it with CCS.

  • in reply to Gyozo Kudor

    Hi Gyozo

    Can you please provide me with some pointers on how you imported IAR SimpliciTI 1.2.0 to CCS. I think everyone on this forum will appreciate it very much as TI is so reluctant and full promises about the release of SimpliciTI 1.2.0 for CCS. Also what version of CCS did you use.

    Thanks in advance

    It was just a test to see if I can compile the simpliciTI 1.2 with CCS. I don't have that project any more. My project was based on the simple_peer_to_peer examples (I made 2 copies of this project one for end device and one for access point.) that came with simpliciti 1.1.  I saw that the two simpliciTI releases (IAR and CCS) had similar directory and file structure so I just copied the sources into my projects that originally used simpliciTI 1.1 and I think it worked. Maybe I had to make small changes, I don't remember any more. Please note that I didn't test this extensively, if I remember correctly I just modified the access point project to use simpliciti 1.2 (by copying the required files into the project) and left the end device project as is, with the original simpliciti 1.1(there was no particular reason, i was lazy, I wanted a quick test) and it worked. In the example you had to push buttons on the end device to toggle leds on the access point. This was just a test, I didn't want to use something that is not officially supported so I reverted back the 2 projects to use simpliciTI 1.1.
