AIC3262 (Multi Channel, Multiple Pin set up)

Hi

Could anyone advice which symbol in GDE belongs to I2S 6 channel input with AIC3262 ?

Appreciate if anyone can share  working register set up  and and PFW files for quick verification.

thanks in advance.

    Hi yw,

    The Multi-Channel_digital_In and Multi_Channel_Digital_Out blocks are used for multi-channel configurations on the ASI1 bus. Note that although all interfaces can operate in TDM mode, ASI1 is the only serial interface that supports multichannel routing like this with the use of multiple data pins. 

    If you can share some more information about what you are trying to implement we could help with the process flow and device configuration.

    Best,

    Hi Zak,

    Attached PFW file that I have created to evaluate multichannel I2S ( 3xI2S as slave mode) using the EVM.

    After downloading PFW file via GDE, open the Code Control software to modify ASI ports as shown in the picture.

    It seems working sometimes , while it is working, I can see probe pin able to detect data from DIN2 and DIN3 while shorted with DIN1.

    (Sometimes I can't see register value updated while controlling from CC software.)

     AiC3262_6ChIn_HP_I2Sout.pfw

    This is the 2nd method I'm trying  to download as I2C command file from GDE panel.

    (It seems working , that I can see DIN2 and DIN3 data from probe monitor)

    1.1_studyMultiChInput_ASI1only.cfg

    (1) I'd like to know which is the proper method/procedure to create working Config file after PFW file is created?

    (2) Is it necessary to go through and check all register settings for every new project?

    Appreciate if you could share the working procedure that you used to practice.

    My target is to explore 5.1 input (I2S multi pin) or TDM input and ( using Mini DSP to do mixing/EQ/DRC) output from both Analog and I2S as 2.1 system..

    thx

    Hey Ye,

    The best method is to update the settings in GDE as you have done so that all of your settings can be exported in a single .CFG file. Note that it is also possible to generate .h files within the GDE. The other option would be to use the GDE to export the DSP registers and the CC GUI to export your configuration registers and combine the two into one configuration file.

    Best,

    Zak
