Transfer SGTL5000 data to iMX6

purvi_billore1 — Wed, 05 Jun 2019 12:05:33 GMT

I am working to design a full duplex telephonic system and I want to send and receive audio data in real time. Therefore,

I have preferred this link https://community.nxp.com/thread/490784.

Can I have sample code to use circular buffer instead of file while transferring the audio data from SGTL5000 audio codec connected to iMX6 over EIM bus.

(example: for telephonic system )

sgtl500‌ imx linux imx6

Thanks and Regards,

Purvi

Hi Purvi

unfortunately I am not aware of such sample codes, in general nxp has special

service for helping with software developing and customizations:

Hi Igor,

Ping-pong buffer C code has been implemented till now and the data is sent over the EIM bus. But there is no way to check if it is real-time or the loopback is happening correctly.

I am happy to share the modifications done on the aplay c file.

Best,

Abhijeet
