Other Parts Discussed in Thread: TLV320AIC3104, BOOSTXL-AUDIO

I know it's coming, it was announced over a year ago. Does anyone know when this boosterpack is finally going to be released?

    Hi Martin,
    This question is best asked in the device forums. Which device are you working with?

    Thanks

    For the TIVA Launchpads. 

    There is a boosterpack by CircuitCo coming based on 

    AIC3104

    Dr. Donald Reay on his newly released book on the TIVA x123 for DSP applications references it -->>

    "........Cathy Wicks at the TI University Program and Hieu Duong at CircuitCo for developing the audio booster pack....."

    Dr. Reay did reply to my inquiry a while back stating he expected it to come out soon. 

    It's been a while though!!

    Thanks Martin. I'll move this thread to the Tiva forums where the experts there would be more knowledgeable.

    Not all collaborations - Academia & Industrial - proceed as hoped and/or expected.   (and rarely to schedule)

    I'd ask, "Who most benefits from a timely release?"

    Pushing (there - the "stake-holders") - rather than (here - humble users) - seems, "more fertile ground."   (perhaps even (almost) holy ground.)

    Absolutely.
    Just wondering. This is just a personal interest. I really liked the TIVA series (how inexpensive and feature rich they are). I amazes me the x123 series can do single cycle DSP instructions in hardware for $13 at 80Mhz. Not long ago (like really not long ago) all we had were the c67xx and the like but way way more expensive (granted they can do higher frequencies but for most audio apps who cares) even the fixed point chips are more expenisve.
    Anyways, I have been waiting for this little codec board. Every other alternative has a caveat I think...I would hope it takes off commercially...

    Hello Martin,

    TM4C12x devices do not have I2S interface which is required TLV320AIC3104.

    What you may be looking for is

    Sorry i meant AIC3104. I did try to edit the original post but i guess I didn't. It is for the x123. I know its coming i know Dr. Wickert over at the U. Of Colorado reviewed it. It's been a while though. Just wondering if anyone knew anything...

    Hello Martin,

    AIC3104 is TLV320AIC3104. And what you are referring to me (based on my reading) is the SPI emulated I2S application note for TM4C12x devices to communicate with TLV320AIC3104 codec.

    This is documented as SPMA042 Application Note

    Uh-oh - poster had such high hopes.    We now learn that (only) via "emulation" may the proper interface be, "teased out."  

    Usually - but not always - such, "Franken-chip" methods prove sub-optimal.   Dedicated & specialized interfaces exist for good reason - cobbling together some attachment seems of little merit when multiple, proper, (other) devices exist - loaded w/the exact interface required...

    Not (all) marriages are made in heaven - this one seems to have escaped that blessing.

    For whatever reason I did not get an email update that there was a reply :(

    I know the reviewers of this board liked it. Emulated SPI to I2S would be ok I think. The price point I believe is coming would also bring the TIVA x123 to a really nice standing with the competition. 

    But from the looks of it no one has heard of this board yet.

    Hi Martin,

    any updates on this?
    I've got Dr. Reay's book and I'm waiting for this booster pack too.

    I contacted CircuitCo and was told (by Clint Cooley) it was in final testing back in October 2015. It should have been released by now. I got tired of waiting and went with the Alternative Dr. Reay had (discovery board + Wolfson Card). I am probably still going to get this board when it comes out.

    Unexplained & extended delays never prove, "Warm fuzzy."    You'll probably "get this board" (only) "if" (trumping "when") it comes out...

    Hello Martin,

    We are in works to launch a TI Design for Mono Audio IN and OUT with low BOM cost.

    Hi Amit,

    Pardon but we cannot tell if your pending "Mono Audio IN and OUT with low BOM cost" INCLUDES poster's (specified) board and/or device.
    Might you clarify?

    Hello cb1

    It uses the booster pack header for the same. However it is not an orderable so the user must get it Fab'ed (I know it is an overhead compared to ordering one)

    Regards

    And - to make clear - does this target poster's specified, "Circuit Co., Audio Booster Pack?"

    Is it correct to think of this as a, "Booster-Pack Light?" (no "standard" board is provided)

    Hello cb1

    I am trying to get the details on the "Circuit Co., Audio Booster Pack", Should be able to answer as soon as I get the data.

    There is a very specific full board referenced on Dr. Reay (one of the leading Professors/reasearchers on Real Time DSP)...

    See a very specific mention on his book:

    onlinelibrary.wiley.com/.../summary

    Inside the book he gives some more info. I have been in contact with him in the last year and he has worked with this board already producing materials/software for it which you can see on his download materials already. I at least know of a University interested on this board so at least some demand is there (perhaps not enough to push it faster, or at all).

    The TIVA series are probably among the cheapest and still robust ARM boards out there. But for RTDSP they lack the codec, which this board would address. There is already a boosterpack with a codec in TI's listing but they charge way too much for it and so it will not take off (IMO) so there is no point in using it if it would only be a one-off to learn how to use it.

    CircuitCo I believe is the manufacturer and as I stated before they were close 6 months ago. Perhaps they hit a priority bump or whatever. Maybe we'll never see this board....but if there is a place to ask, isn't it here?

    Hi All,

    I have only today become aware of this thread. Here, belatedly, is what I know of things.

    A small number of CircuitCo audio boosterpacks were manufactured at the end of last year. Several were distributed to, and reviewed by academics, including Prof. Mark Wickert. I don't know why more boards have not been manufactured/put on sale by CircuitCo. The last thing I remember is optimism being expressed that it would be put on sale. The CircuitCo boosterpack (successfully) uses the I2S emulation method from the TI application note. It would be nice if it did eventually see the light of day. My impression is that TI devices including the TM4C123 launchpad are popular in universities.

    However, an alternative hardware platform for use with the book exists. It's the Cypress FM4 S6E2CC Pioneer board. Software for this may be downloaded from the book's companion website and although the board is not mentioned in the book, the experience of running the program examples from the book on this is very similar to that of running the program examples on the TM4C123. The Cypress FM4 runs at 200MHz and uses a Wolfson WM8731 codec - the same codec as used on the TI C6713 DSK (although the Wolfson design was licensed as an AIC23).

    The CircuitCo audio booster pack and Cypress board are demonstrated here

    and here.

    Hi,
    I am also waiting for the circuitCo audio booster pack since last year. I googled several times, but I can't find it.
    Do you think this board would work: store.ti.com/BOOSTXL-AUDIO.aspx (Audio Signal Processing BoosterPack Plug-In Module).

    Thanks!

    Hi Thiago,

    The BOOSTXL-AUDIO booster pack won't work (straightforwardly) with the TM4C123 Launchpad. It's designed for use with the MSP432. Frustratingly, and despite all being based on an ARM Cortex-M4 core, the TM4C123, TM4C129 and MSP432 each have different I2S (or I2S-equivalent) peripherals. Furthermore, I2S ((one) industry standard for audio data interface between microcontroller and codec device) is not covered by the launchpad/booster pack interface standard.

    In any case, the BOOSTXL-AUDIO booster pack doesn't have the capabilities of a dedicated stereo audio codec. As far as I am aware, it is mono, the DAC provided is not a dedicated audio DAC, and the microphone input is routed to the 'instrumentation specification' ADC in the MSP432 without 'audio spec.' antialiasing.

    I don't  know why circuitco haven't manufactured the AIC3104-based audio booster pack that we developed.

    As I've mentioned previously, if I were to recommend a hardware platform for use with my book, it would be the Cypress FM4  Pioneer board.

    However, I'm hoping shortly to add to the companion website for the book a version of the software to work with the original prototype audio booster pack that I first built in 2013. Also, I hope to add the pcb artwork so that people will have the option of fabricating this themselves.

    The design is based on the same codec (TI AIC23/Cirrus Logic WM8731) as used in the C6713 DSK and in the Cypress FM4 board. I've attached images of the first prototype board. This used an AIC23 codec and Lumberg jack sockets. I am just testing a slightly different version of the boosterpack that uses the less expensive Cirrus Logic WM8731 codec and more widely available Switchccraft jack sockets.
