i2s_channel_enable() function
Enable the I2S channel
Syntax
Implemented in ![]()
i2s_common.c:1158
Notes
Only allowed to be called when the channel state is READY, (i.e., channel has been initialized, but not started) the channel will enter RUNNING state once it is enabled successfully. Enable the channel can start the I2S communication on hardware. It will start outputting BCLK and WS signal. For MCLK signal, it will start to output when initialization is finished
