TAS3204 Analog Input Control (0x12) and other i2c registers

Jeff - the engineer who needs to study/answer your query is out of office this week.  I hope we can provide an answer early next week.  Regards, Lester Longley

Susan,

Any new information on this? Thanks.

Jeff,

Just started looking into this.  Where did you get this I2C_addr.addr file? or how did you generated it?  Frankly, I couldn't find this file in my build folder, there must be some option that you selected that I never used before.

But I looked at the regester info you copied and pasted in your first post, it looks really old.  After you build your project, go to tools->I2C overview to get the real list if you don't trust the manual.

There is a button at the bottom of the I2C Overview tool window that says "Generate .addr file". It takes the register list and writes it to the I2C_addr.addr file, a text file. This file exactly matches what I see on the I2C Overview tool display. The first 31 registers (0x00 -> 0x1F) are TAS3204 registers. The components from my design start at register 32 (0x20).

Page 49 of the manual says to not trust the 12-1 table of registers in the manual as the registers may be remapped when using the PurePath GDE. However the registers in table 12-1 in the manual don't show up anywhere in the I2C Overview display after I build my project. I'm a bit confused.

Jeff,

I just generated a .addr file as you instructed, since it's just the duplicate of what I2C Overview tool, I've never used it, not sure whether it's useful in any way., guess just a record keeping thing.

Here is my version of the .addr file, looks quite different from yours:

Just wondering whether you had an older version before, but the PPS 1.88 b5 got messed up during installation.  Can't explain why your files are different from mine.  Usually, framework I2C registered are reserved, they won't get remapped, but still, always trust the numbers in I2C overview window, which are the ones being used.

Susan,

I completely removed then reinstalled PurePath Studio. Then I completely rebuilt my project from scratch. I now get the same reserved registers you have. I'm good to go for now. Thanks for your help.
