Hi! Since you always helped me answering other topics, I've decided to create my first topic. I'm currently working on a VOIP application with mini2440. I've searched all web and still couldn't find any sound example (How to read the microphone samples, how to output raw pcm data, etc) Could anyone please send me some sample codes? Or at least show me how can i access the audio interface? I'm running a QT app under linux. Thanks, Andrew.
I'm desperate... anybody?
UP!UP! Is there anyone willing to help me? I can't believe nobody ever tried this.. thanks
Hey Mr.Andrew... did you get any stuff you needed? please reply!
Recently I have tried LinPhone on Mini2440. It builds fine, also works. But the Mini2440 hardware does not support the correct sampling rates to use the common decoders and encoders. It needs to re-sample all the time which seems to overload the CPU. I connected two Mini2440s via network and ran LinPhone on both. Everything works fine up to the call. After the "answer" command both systems run at 100 % system load, the audio DMA stops working (or to be more precise: times out all the time) and LinPhone cannot work correctly.
Please search the forums - Mini2440 cannot do duplex audio so it has no chance of working! Mini6410 works fine... Andy.
