K8055 - Audio via analogue in/out

Hi!

Does anyone know if the analogue ins & outs can be used to receive and send audio (via speaker & microphone)?

For example I want to be able to play a wav file through the board via the analogue out, and record audio input via the analogue input. Has anyone here achieved anything similar?

Any code snippets would be great.

I’m a c#/VB.net programmer, but any language code would help point me in the right direction.

I’ve had a scan through the forums, but can’t find anyone using the analogue ins & outs for audio.

Regards,
Pete

Sorry to say but the sample rate of the K8055 is too low for the audio signal.

Shame…

I’ll just have to use the mic/speaker sockets :neutral_face:

Thank you for the reply.

in fact !
10ms for scan = F=1/T => f=1000hz
1khz/2 (law of ???) = under the sound of voice, and whit 10bit, your samples is very bad (like my inglish :cry: )
Also you can use it for activate output for a “light game play” for example
in french :
les entrées analogique de cette carte ne permétteront pas de reproduire un son au dessus de 500hz et de plus avec un échantillonnage de 10 bit la qualité sera vraiment médiocre. En revanche vous pouvez les l’utiliser pour faire un jeu de lumiére avec chenillard. cf ma source :wink:
