Title: A10-LIME audio output
Post by: dejohnny on January 20, 2015, 03:16:06 PM
Hi,

I'd like to use the audio output of a A10-LIME board. According to the user manual page 31 (6.9.1) some further components are needed:

This connector features the processor signals needed for audio
headphones output and microphone
input. Please note that not only the connectors but also the rest of the
schematic is missing! You
would need to add resistors and capacitors.

I checked the schematic for hints regarding the required circuit but could not find any info. Is this documented somewhere, or does anyone know how to use the audio output feature?

I'm planning to feed the signal to a line level input, can I get away with simply connecting up HPOUTL, HPOUTR and HPCOM?

See the schematic for the A10-OlinuXino-MICRO:
