sai_interrupt_record_playback#
Overview#
The sai_interrupt_record_playback example shows how to use sai driver with record and playback features:
In this example, one sai instance record the audio data from input and playbacks the audio data.
Supported Boards#
EVKB-IMXRT1050
Hardware requirements
Mini/micro USB cable
EVKB-IMXRT1050 board
Personal Computer
Headphone(OMTP standard)
Board settings
No special settings are required.
Prepare the Demo
Connect a USB cable between the host PC and the OpenSDA USB port on the target board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Insert the headphones into the headphone jack on EVKB-IMXRT1050 board (J12).
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
Note: This demo uses both headphone mic and board main mic(P1) as input source. The headphone mic provides left channel data, and main mic (P1) provides right channel data. If users found there is noise while do record operation, most probably it is the headphone standard issue (OMTP and CTIA standard difference). You should use the OMTP standard headphone. You can disable the left channel by using an headphone without microphone feature.
When the demo runs successfully, you can hear the tone and the log would be seen on the OpenSDA terminal like:
SAI example started!
