Georg, My original plan was to design a generic add-on board for embedded single board computers that includes an audio codec, FM tuner, and optional text-to-speech. I still have that plan but may make several variants on this, I have lots of interest in mobile audio beyond what is available today. TI has chips that can convert USB audio (driverless on host) to I2S and/or S/PDIF, which would allow for some really interesting possibilities in supporting different kinds of codecs, DACs, ADCs, DSPs, faders etc.
Is it only the FM tuner you are interested in? Do you have skills with Eagle CAD? I have surface mount reflow oven and can solder any part easily. I also have Eagle commercial version but at the moment do not have a lot of time. If you want to work with me on schematics and CAD design for starters that would be cool. Look at the TI PCM29xx USB audio codecs, this is a way to interface via USB to other audio devices. It is also interesting that Neo uses WM8753, as I have been wanting to work with this part for a long time, since it has dual audio codecs voice and hifi. The TI TAS3103 also looks pretty interesting. I have some SI4701 FM tuner chips here already, have their USB FM radio stick which is really a demo of the chipset, and have collected lots of info on these. I also have sample WM8753, will be getting more, and development boards for both of these chips eventually. -- Doug Doug Sutherland Proficio Research http://www.proficio.ca/ ----- Original Message ----- From: "Georg Michelitsch" <[EMAIL PROTECTED]> To: "List for OpenMoko community discussion" <[email protected]> Sent: Friday, November 09, 2007 1:16 PM Subject: Re: FM radio reception on neo/openmoko and some other questions > Daniel Gustafsson wrote: > > > > > > Implementing an FM sender would however make the Neo hard to sell on > > markets where personal FM transmitters are illegal (however weak the > > signal is) such as Sweden.
