  • Forum Post: aic3204 test routine problem in I2S interupt register

    Russell Barr17013
    In the sample code aic3204 that comes with usbstk5505 there is a serious flaw in the routine aic3204_tone_headphone. This routine outputs a 1kz tone through the I2S port to the aic3204 codec. When you listen to the tone you can hear artifacts in the output that sound like missing data points. If ...

    I have a program that runs fine under the CCS4 debugger. When I transfer the program to flash the program does run but it only outputs audio. It does not process the audio I put into it. If I hit it with high level audio momentarily it starts to work. I have added the code from the GEL file...

  • Forum Post: Test tone from aic3204 example distorted - what is wrong?

    Geza Anders
    I tried the examples on the eZdsp USB Stick installation DVD. The aic3204 example should produce a 1 kHz sine tone but this is not the case. What I can hear is a distorted tone with a frequency of about 740 Hz. In contrast to this, the built-in test program clearly produces sine tones with 1000 Hz and...

    Shahar Yuval
    I'm trying to run the audio filter demo on the C5515 ezdsp board with a microphone input. From the AIC datasheet I understand it is possible to amplify the microphone signal by switching on the PGA preamplifier block in the codec. After consulting the register map, I made the following changes to...

    I am having problems programming my eZdsp5535 to output a signal on the AIC3204. I have managed to output successfully using the demo code, however, I am trying to pre-generate the output signal and it would seem to make sense to put into the DMA before outputting to the AIC3204 (via the I2S).

    Hi all: I am a bit confused by this "playback path" as it is stated in AIC3204 datasheet. Does it mean "loop back whatever AIC3204 receives from its inputs to its outputs in real time?" Can anyone assist me? Thanks
