Closed r3d4 closed 4 years ago

r3d4 commented 4 years ago

Reworked commit to better integrate into Ka-Radio32. Almost only needs changes in audio_renderer.c

Vasilis-7 commented 3 years ago

Hi. Is it working the SPDIF out?

marcinmaster999 commented 3 years ago

spdif works directly without vs1053 so only soft mp3 works and you hear crackling noises when switching channels but sounds works good ;)

Thank you for your answer. So, I will attach an optical Transmitter at the I2S data pin. What will be the option for the audio output, in the web interface of KaRadio ?

I have the current version, and i don't have option for SPDIF output.

marcinmaster999 commented 3 years ago

maybe try this https://github.com/r3d4/Ka-Radio32/tree/SPDIF

briankdlee commented 3 years ago

I can choose sound output as SPDIF with the recent version 1.9 R10. But I wonder how to wire. Can I connect from I2S pin to optical port(i.e. PLT133) directly? Isn't there needed any resistors?

r3d4 commented 3 years ago

Yes, you can wire PLT133 Pin 3 (VIN) directly to I2S data pin. PLT133 has logic input so no resistor is needed You also need to connect 3V..5V power supply at PLT Pins 1(GND) and 2 (VCC). Also put 100nf ceramic capacitor between VCC and GND direct at PL133 pins.
