PP-SALB-EVM: Linux driver, PWM, Laser proposal

Alen Barisic

Part Number: PP-SALB-EVM
Other Parts Discussed in Thread: TAS2563

Hi,

1. Is the PWM interface for connecting 2 Mems microphones already supported?
2. Is there a recommendation for a cheap laser for measuring the membrane deflection?
3. Does TI offer a Linux driver for implementation in our system?

Thank you for your support.

Alen,

May you let me know actual device? we can go check if we can support the linux driver.

Hi, Alen,

Regarding the linux driver, could you take a look at this e2e thread and see if it works for you?

Regarding the recommended laser, for small tests of membrane deflection, we use the Keyence LK-G5000 series. This laser is practical for this kind of tests.

Unfortunately, the PWM interface for 2 MEMS mics is not supported yet.

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

Best regards,

Hi Luis,

thanks for the support.

Can you already estimate when the PWM interface for 2 MEMS mics will be supported?

Hi, Alen,

I will contact our software team in order to get an answer about this. So far there are no plans to have this feature supported, but I will contact them in order to include in our list.

Best regards,
