This leads me to believe that the microchip example code itself is actually flawed, rather than my modifications or changes to the hardware.

Did you figure out how to fix any of them? I’m not compiling the kernel I hope so is it something I just edit? Sign up using Email and Password. Buy another demo or replace the chip; if you are lucky not to get another bad – it will work.

Mostly testing on the MacOS which has very robust audio drivers – that’s one of the main reasons i use a mac when performing music on stage where audio has to work every time. Configure the codec registers for sample rate control [setting the codec frequency for any PCM signals for various sampling frequency ranging from 8KHz to linx KHz] codec bit length and master mode settings etc.

Connect Codec with two microphones. I’ve rewritten most lunux the project. Note we are using 3. ARM Processor architecture training undergone. It isn’t found on the Ubuntu image. It seems the logical approach is to use a userspace program to talk to the AIC rather than try to create a device driver. My board runs out of the box Linux – Ubuntu Audio stream from the computer over USB works fine usually.

A little more proof that this is a badly written demo.

That will resolve a big problem for me! If so, how the heck aic32254 i go about doing that? An update to the code example will be available shortly on the product page. Somebody must have built it, perhaps your board vendor? Besides my “embedded” function, the board also has to be a general purpose Linux PC. Forum Themes Elegant Mobile. Tghe last time I built a kernel with any understanding lknux back in At the same time, the Audio Out endpoint is marked in the USB descriptors as Asynchronous, meaning ideally that the host should be compensating for these clocking differences NOT the device I’m trying to build a simple USB audio interface into a project.

Seriously, you will tear your hair out before it’s done. Pacs server will respond with the results in HL7 format. It would help if there was a shred of documentation in the example code especially the USB descriptorsbut there are practically no comments anywhere and its taken me a long time to piece together what little i know about how it’s working. Perhaps a simple char mode driver?

Results will be decoded and stored in the DB. Not enthusiastic about that, but its so close, maybe it can be improved – i have a few ideas about how to improve upon the way the clock adjustment is done in the example code. Wes – Jump in!

Should I upgrade my kernel? In my experience this was related to a specific chip. All that I need to do, as far as I know, is to copy linuc codec’s “program” to it over the I2C bus then read it back poor man’s load check.
