Part Number: TAS2555

Hi Team,

The customer is experiencing below issue and needs your help.

At present, the customer has completed the debugging of the spk by using PPC3 to generate the bin file, but how to configure the timing of the I2S interface in PPC, he did not find this project. On the android platform, he initializes the 2555 registers through the bin file. The customer wouls like to know how to include the i2s configuration in the bin file?

Thanks.

    Hi, Annie,

    In PPC3, you can find several options in the End System Integration, you should first select the Mode, then the Sampling Frequency and at the end the Clock Source and its Frequency.

    Unfortunately the format is not selectable within PPC3 so it uses the default I2S format. If you need a different format or bit offset, you would need to do some additional register writes after initializing the device.

    Please let me know if you have additional questions or comments on this.

    Best regards,
