Hi

I was trying to develop an audio app in ezdsp 5535 that uses 3204.The OLED was updated time to time with SAR updates(on pressing key) .But the moment I display something on OLED,the audio gets corrupted.Both aic 3204 and OLED uses I2C writes.Can you please help me to fix this problem.

Regards

Hi,

Do you use BIOS in your project? How do you transfer audio data using DMA, interrupt or polling? Audio data transfer should not be interrupted.

Regards,

Hyun

Hi Hyun,

The audio transfer is done using DMA and I am not using BIOS.As both AIC3204 & OLED is configured using I2C writes,can this be the point of concern??

Regards & Thanks
