    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...

    Hi J. Arbona, I just switch from AIC3254EVM-K to AIC3254EVM-U and want to evaluate the Codec with my own software. Looking on a usb monitor I noticed that the USB protocol for reading and writing registers is a little different from what is documented for the EVM-K. Is there a documentation of the...

    unit worked for a while but now when plugged into usb port says usb port not recognized. After one plug in, it had it identified in the device manager as an xds560? also not recognized. I had tried to run the unit with the evm-u software, per the post of 26 dec, 2009 by J arbona.

    Hi, I want to do some testing on the TLV320AIC3254 Evaluation board at a sample rate of 192kHz. I have been changing the sample rate by writing firmware files through the EEPROM writer tool, but there are no files provided for sample rates over 48kHz. It would be great if I could get hold of the...

    We are starting a new project with several TLV320AIC34 on the same McBSP. In this project the relative synchronization of the various channels is important, and I have the following questions: - If several devices (configured as slaves) are cascaded on the same McBSP bus, is it possible for them to use...

    Jesper Gormsen Kragh
    Hi After a successfull set-up of the PMC3070-K software (sloc229) and PPS Home Audio, PPS prompted me to download new code to the EEPROM during first download of PPS generated code. This resulted in a lost of the EEPROM fw, and hence my development boards will no longer connect to the PCM3070-K...

    Hi, When building the framework AIC3254App8x4x, it adds quite a few DSP and coeff entries; I've managed to get 8KHz sampling and playback working when the DSP and coeff entries are removed; however with the DSP and coeff entries, it stops sampling or playing audio. I've attached two .cfg files...

    Hello. I am experimenting with the TLV320AIC3254 evaluation kit. My target goal is to produce a low power shortwave radio, where most of the processing is done by the 3254. Currently I am having trouble to understand how the ADC processing works. I am confused about which of the processing blocks...

    Hello. We are designing a SSB receiver using the Weaver method with the TLV320AIC3254 part. Our system relies greatly on properties of the ADC decimation fiters and the decimation filter A seems to fit the bill for us with sampling frequency of 44100 sampels per second. We would greatly benefit from...
