easrc_p2p_out_sdma#
Overview#
The asrc_p2p_out_sdma example shows how to use asrc driver with sdma:
In this example, one asrc instance convert the audio data stored in flash/SRAM/DDR by SDMA channel and then playback through SAI directly.
Supported Boards#
EVK-MIMX8MN
Hardware requirements
Micro USB cable
MIMX8MN6-EVK board
J-Link Debug Probe
12V power supply
Personal Computer
Headphone
Board settings
No special settings are required.
Note! This case does not support TCM targets because of limited memory size. This case does not support flash targets because of SDMA2 burst DMA not supporting for accessing flexspi.
Please note this application can’t support running with Linux BSP!
Prepare the Demo
Connect 12V power supply and J-Link Debug Probe to the board, switch SW101 to power on the board
Connect a USB cable between the host PC and the J901 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.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
When the demo runs successfully, you will hear one converted audio clips. The log would be seen on the terminal like:
ASRC peripheral to peripheral SDMA example.
Playback converted audio data
sample rate : 16000
channel number: 2
frequency: 1kHZ.
ASRC peripheral to peripheral SDMA example finished.
