At the (DSP Appl. with C6713 and 6416 )book, Dr. Chassaing says in CHP 2 Ex 2.3:
Experiment with this project, inputting different signals into each channel and outputting from each channel using adapters and stereo cable. Verify that you can select each input and output channel independently.
I have modified the example's code as below:
...
AIC23_data.channel
=input_left_sample();
AIC23_data.channel
=input_right_sample();
output_right_sample(AIC23_data.channel
); output_left_sample(AIC23_data.channel
);
...
I think that I assign right input to right output and same for left ones.
But I hear left or right inputs from both sides of headphone.
