Hello Very nice work ! I using the LTC SMPTE Firmware and sending LTC very nice. But now i try to read LTC an wondering how to get the Audio in ? For Output of the LTC i use a Orange Pi Zero an the Zero Interface Board. Can i also receive LTC with this board ?

Thanks a lot

Hi @lyon470

But now i try to read LTC an wondering how to get the Audio in ?

I have simple unbalanced example here -> http://www.orangepi-dmx.org/orange-pi-smpte-timecode-ltc-reader-converter/hardware

I am working on a proper balanced input (and output). Please keep an eye on my website for that publication.

Thanks, Arjan

Thanks for your fast reply.

You're welcome!

Yes. Note that the VDD for the OPAMP is 3V3. And basically any rail-to-rail OPAMP can be used. Background information: https://www.analogictips.com/amplifiers-rail-to-rail-single-supply-mean/
