TLV320AIC3111: Beep Generation

Zeal Bhatt

Part Number: TLV320AIC3111

I want to generate a beeping sound using the TI TLV320AIC3111. With my current codec settings, I get just a click (barely hearable from the speakers).

I am attaching a few configurations that I have already tried.

Please help me out with a script that would increase the beeping sound (Like an alarm beep.

Zeal,

I'm sorry you're having some difficulty. I'm sure we can help resolve your issue. I just have a few questions for you

1. What is your Fs? from script 3 it looks like you have an Fs of 8k, can you confirm that my assumption is correct?

2. are you using an EVM or your own design?

3. what beep frequency and beep length are you aiming for?

best regards,
-Steve Wilson

Dear Steve,

1. Fs = 48 kHz

2. I am using my own design.

3. Beep frequency = 1 kHz, Beep length = 017700h (Burst length = 2 seconds)

I really appreciate your help!

Thank you.

Dear Steve, I am still looking for a solution to this. It'd be great if you could look into this soon.

Thank you.

Zeal.

Zeal,

This is the same Fs, and beep frequency as the Datasheet example on Pg59 of the Datasheet. The only difference would be the beep length, which you have already calculated.

Are you providing the Codec with I2S clocks? The DSP will need to receive the I2S clocks at least briefly in order to create a beep.
