    PurePath Option "Generate complete applications" and "Generate application patches" generates the same driver and config outputs. Is this a bug or am I not using the Application correctly? Also PurePath generates three structures, REG_Section_program and two miniDSP arrays. Can I...

  • Forum Post: PurePath support for LEC on AIC3254 miniDSP

    Wayne Duquaine
    The AIC3254 miniDSP currently has support for Acoutic Echo Cancellation (AEC) in PurePath GDE. Any plans for providing Line Echo Cancellation (LEC) as well ? It would be very handy for Telco based applications.

    Mikael Bohman
    In the premade examples from TI, the AEC demo uses I2S as the input/output for audio. In an embedded design, it's intresting to use the A/D & D/A of the CODEC for input/output combined with the AEC. Is it possible to instead use analog Input/Outputs under the AEC framework? And if so, which...

    I am have trouble understanding exactly what needs to be written to the volume component to change the volume. I am using an aic3254 as an SPI device. The closest I come to making this work is by writing a 24 bit coefficient to addresses 24, 25 and 26 (page 44). This changes the volume on the first write...

With manual register settings I mean all the analog routing setup and clock configuration etc as they are apparently not included in the generated file. If I add...

    I'm using PurePath 1.88 b5 to configure my TAS3204 and I'm having very unusual problems with my mixers. It seems to me I'm not able to set gain for the individual inputs. For example I have input 1 set to 1dB and the remaining 3 to -16dB meaning they should be practically muted. However the...

    My question is about the operation of interprocessors, about which I feel I'm missing something important. In some example AEC process flows, for example AIC3254_AEC_12LE, the output 1 of DSP_D_DSP_A_AEC_LE is directly linked to the input 1 of DSP_A_DSP_D_AEC_LE, and then from its output to AEC_12LE...
