TAS5755MEVM: TAS5755MEVM Mixer

Marshal,

Please see the following corrected image for the mixer information:

The number in red is the subaddress of either register 0x53 or 0x54. 

For any one mixer subaddress, the gain setting is as follows:

0 = 0x 00 00 00 00

1 = 0x 00 80 00 00

0.5 = 0x 00 40 00 00

Hope this is clear, let me know if it's not.

Regards,

-Adam

Thanks, Adam.  This block diagram makes a lot of sense to me, but the GDE does not show all the blocks that you have on this picture.  For instance, if I want to get L+R into both channels 1 and 2 then I should mix L+R in mixer55 (I2C address 55) by mixing 0.5 into mixer_0 and mixer_1.  Then the output of mixer55 would be L+R (mono).  I would then use mixer 53 and 54 to get mono through channels 1 and 2 by applying the following mixers: mixer_3=0; mixer_2 =1; mixer_1 = 0; mixer_0=1;  This would then give me a mono signal in channels 1 and 2 that would go into the 2nd set of biquads for each channel.  Correct?

The only problem is that I do not see anywhere on this GDE where to edit mixer55.  I wrote directly to address 0x55 and got the mono signal working, but how come this block is not shown in the GDE?  When I export the I2C registers to an init file, register 0x55 does not retain the value that I had written to it using the I2C writing tool.  How do I edit this register and have it save it's value for when I write the I2C registers for implementation?

I hope that question makes sense.

Thanks,
