SPDIF code examples

borgestrand-ber — Fri, 12 Apr 2019 14:03:30 GMT

Hi,

are there code examples for the SPDIF interface on the RT processors?

Ideally there's code which takes SPDIF -> I2C -> DAC chip on dev kit.

Best regards,

Børge

I²C DACs are rarely used for audio applications (low bit rate), did you mean I²S?

pls find the attachment, which is from RT1052 driver sample code

Thank you Joan!

I will read up on this code.

Where do I find a full catalog of example and driver code for RT devices, not just the one board my SDK is built for? While I'm prototyping on an RT1050 dev kit, my application will probably go into an RT1015 or RT1020 in the end.

All the best,

Børge

we don't have such catalog for all of RT devices, why do you need this catalog, and sorry for my typo, the spdif driver is from RT1050

OK. Where do I browse for drivers and code examples?

I have identified MCUXpresso's Import SDK Example button, but as an NXP RT freshman I don't know where else to browse for code examples.

Best,

Børge

if you download the sdk, you can find the sample codes and drivers, if you use RT1050, you can refer to the "i.MXRT1050 EVK Extended Feature Example Code and HW guide" from the link as below:
