Description

i2s_channel_t::I2S_CHANNEL_MONO

= 1

I2S channel (mono), one channel activated. In this mode, you only need to send one channel data but the fifo will copy same data for the other unactivated channels automatically, then both channels will transmit same data.

= 2

I2S channel (stereo), two (or more) channels activated. In this mode, these channels will transmit different data.
