nrfxlib LC3 library for cortex-m4

[aonsquared]

Hi,

We're developing a device based on the nrf52840.

We want to read LC3-encoded files on the filesystem, decode them, then send the data to the i2s peripheral. However, we realised that libLC3.a is only available for cortex-m33, which is the nrf53.

Given that we're only playing back files from the filesystem, we don't want to upgrade to the nrf53 just to do this. Can we get libLC3.a for the cortex-m4 too?

Hello,

The nrfxlib implementation of the LC3 codec is only for the ARM Cortex-M33, but there is another implementation available in Zephyr: https://github.com/zephyrproject-rtos/liblc3/tree/main. I suggest to use the latter in your project.

Best regards,

Maria
