Re: Analog_Bridge for the Raspberry Pi

Steve N4IRS

I hope it will be a short delay. Once we have a validation program, we will know more. One of the options we are considering is to change the RPi version of Analog_bridge WITHOUT support for USB. It would be AMBEserver only.
Once we have the validation program I will test on other ARM based systems. OrangePi, NanoPi, Odroid etc.

We have been talking to them for a while.

Thanks, Steve

Hi Steve,


Looking at NWDigital's site the GPIO version is out of stock, and they are recommending people purchase the DV3000u, so if there's issues maybe they could assist?

It's actually specific to the ThumbDv (DV3000u) It may well be power. The existing initialization code follows the NWDigital spec but does not prove actual valid data to and from the Vocoder.
As a note, we are not seeing the problem with the GPIO based Vocoder. I'll follow up as we know more.

Does this include ThumbDV dongles?

If it's solely power related, maybe using a powered USB hub will help?
