nrf9160 pwm&i2s example

Hi,

Here's a pwm example that shall work with most nRF devices:

For I2S, there's an example here that works with the nRF52840 and nRF5340:

You can also use the nrfx_i2s driver directly, by enabling it with CONFIG_NRFX_I2S=y, and interfacing the nrfx_i2s driver directly in your application.

Kind regards,

Håkon
