I guess it might even be possible to (depending on your speaker configuration) link multiple inputs at the same time allowing the Google assistant to still talk to you when in radio mode. However then your music would still have to be paused manually. (using something like this I know it's not ideal but it works.
We have read all the post again.
To be honest there is no good solution for both, DAB and FM frequencies. All solutions that cost more than 40-50$ are not interesting for us. We wanted to give a try with uGreen, however there is no support for FM and after few emails exchange looks like they are not interested in further development. Our opinion about SDR dongle stays the same - too high resource consumption. Seems like, for know, the only solution would be to use Si4702/03-C19 wih Worldwide FM band support and stay with welle.io for DAB and DAB+. This also means that audio sources have to handled manually by user. For now, development of audio-mixer is out of scope for us. As always, let us know your thoughts.

Sorry just not understanding what that means for the end user.
Do you have a passion for cars?
Then create a page for it at Car Audio Central A great place to document and share your OpenAuto Pro projects.

With the imminent launch of the Raspberry Pi 4, with significantly better RAM and CPU performance, would you reconsider pursuing software support for an rtl-sdr device?

I was thinking about building a solution with the Silicon Labs SI4689 chip. Why? The SI4689 offers all-in-one, ultra-low power, multi-band digital broadcast receivers to support global analog and digital radio standards, including AM, SW, LW, FM, FM RDS, HD, DAB, DAB+, DMB, and DRM(30). If you create a solution with this one chip it will work worldwide! I am sharing some details below including links to product details and some existing code. I am also going to look into how much the eval kit costs. I am sure it's expensive, but good for testing functionality with OpenAuto Pro before deciding to use this chip. Then possibly on to a custom board using the SI4689 chip to reduce cost for sales. SI4689 Datasheet Evaluation Board
Someone has even done some of the coding work so we get a head start! teknoid Github and elmo2k3 Github (06-24-2019, 05:18 PM)frankpintosr Wrote: I was thinking about building a solution with the Silicon Labs SI4689 chip.

Still there is no ready to use board available for everyone. This mean that you have to design our own PCB and deal with EMC, radiation, or check how it behaves in moving car where there is a lot of disruptions... and after survey we have made some time ago, users expect product in price range 30-40$. Quite challenging. @[b]INS4NITY [/b]This could be good idea.

I googled the board and found it, with a 3 week lead time. But the heart attack came when I saw the price! Mouser $688 Digikey $754 Obviously that is not at all feasible, so I will look to see about developing a board. If anyone has the skills to design such a board I would love to enlist your help! |
