When the microcontroller can transmit data i2s peripherals, you will encounter the concept of left and right channels of data, what data it left and right channels? What is the specific format? With the usual stereo data, what difference does it make?
The following data with reference to specific examples will be briefly described.
The so-called left channel data is only for the left channel (note that the logic analyzer to identify left and right channels are reversed, and Wikipedia does not match) the LR clock, the data lines only data, see below:
Similarly, the right channel data, that is, only when the LR clock right channel, only the data line data, as shown below:
The stereo data does, it is regardless of LR clock line is high or low, the data line data are:
