Hello

I succeeded in LED output using this code. However, I have difficulty adding new functions by using this. I want to know how to combine the colors of LEDs and how to turn them on at the same time. (e.g., so that the first and third LEDs light up)

Can I get some advice on this?

Thank you.

Thanks Mahesh, even after three years I can also port it to the latest SDK with minor changes.

For those of you who might need some hints from this page later, the nrf_drv_i2s_start API has changed a little bit and the following modification will make it work again:

nrf_drv_i2s_buffers_t const initial_buffers = {
.p_tx_buffer = &m_buffer_tx[0],
};
err_code = nrf_drv_i2s_start(&initial_buffers, I2S_BUFFER_SIZE, 0);
APP_ERROR_CHECK(err_code);

Thansks! This was done on SDK 12.2.0 but should be portable to the latest SDK...

Very cool. Which SDK will the code examples compile with?
