Example Description
|
||||
|
||||
This example describes how to use i2s by using mbed extend api
|
||||
Use TXRX mode to archive software bypass mode
|
||||
|
||||
NOTE: RX need clock generated by TX. This mode can do TX/RX in the same time.
|
||||
|
||||
Procedure:
|
||||
1.Plug ALC5651 shield to Ameba HDK
|
||||
|
||||
2.Run the main function.
|
||||
|
||||
3.Plug earphone to Green phone jack
|
||||
|
||||
4.Plug audio source to Red phone jack
|
||||
|
||||
In this example, you can hear the fluent audio source from the earphone.
