Hi Judge

No, this example was made for GCC only unfortunately.

hi Torbjørn，

Thank you very much for your reply.

This is a GCC project.Do you have the code use keil or segger or IAR ?

Hi Judge

Please find a small example attached. It's an un-official example made by one of our software guys, and is provided "as is". In other words, use it at your own risk ;)

hi Torbjørn，

I still having issues with this.If you can provide a 52840 that contains the OPUS codec, that's great !

hi Torbjørn，

I tested OPUS algorithm performance use SR3 v1.2. DK10040. PCA63519.

I want to test the performance of silk mode.I used the following configuration, but found it didn't work properly and I couldn't see its CPU consumption.I want to know something about the use of silk mode.

And do you have a migration of a simple project that includes the OPUS algorithm?

Sorry for the delayed response. Stian is currently unavailable, and I will help out in the mean time.

Are you still having issues with this?
Migrating the OPUS codec from the nRF52832 to the nRF52840 should be relatively straight forward, since the nRF52840 is basically just a more full featured version of the nRF52832 with additional memory and peripherals.

If you are still having problems I will try to provide an example for the nRF52840.

Best regards
Torbjørn

Is there any plan to add support for 52840 to SR3? I find there is much code to be changed. I can't even broadcast now.

hi Stian，

Can you provide a simple demo that has already migrated the OPUS codec?

Compilation has a lot of errors, and I can't fix them.

You can use the opus library on nRF52840 as well. Just start a project for the nRF52840 and include the opus codec.

hi Stian，

Will there be a 52840 version of SR3 in the future ? Because I found my 52832 RAM was not enough !

I use OPUS codec which consumes a lot of RAM.

hi Stian，

For example, I want to transplant OPUS to this project:

nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_uart

I collect the audio data and send it to my phone through OPUS encoding.

Unable to resolve this error, .h file has been included.

Hi, sorry, I don't understand what you want to migrate. Migrate OPUS to where? Any error messages during migration?

The SR3 only includes a demo version of ANR which adds a beep to the signal at regular intervals. If you want to get the full version contact vocal.com, maybe they have some numbers on the efficiency as well
