Re: dmr for nwdigital

Barry,

If you are asking about the DV3000 or the ThumbDV, then yes I have done this.  I am in the middle of working on an application that allows one to use the DV3000/ThumbDV just like the DummyRepeater mode works for DStar.  I have been using it for a while and it works very well on both TX and RX.  This is part code is an outgrowth of a project to create a gateway between DMR and ALLStar/Asterisk and that project is nearing its completion.  Once I get a chance, I will open source the code and others can build on my efforts.

A bad youtube video:

DMRDongle480

 



The quality was not up to what I wanted so I never released it, but I am tied up with some family things at the moment and this will have to do.  I will do a better one at some point.

Has anyone been able to run DMR on the nwdigital?

Re: Raspberry Pi 3?

There have been some significant changes to the serial port (ttyAMA0 is now used for Bluetooth, and the new ttyS0’s speed depends on the GPU clock), so probably not without some work.

We don't have one for testing yet, but there shouldn't be a reason why it wouldn't. I'd start with the PI 2 configuration.

Any interest in the Raspberry Pi 3?
We’re interested. I have three on order.

I'm guessing not, as from your previous descriptions the UDRX wasn't processor-bound.

Nice that they put Wi-Fi and Bluetooth onboard, but pity they didn't provide an antenna connector for applications like yours where it will be in a metal cabinet.
There actually is a set of solder pads on the bottom side of the board to solder in a connector. That being said, it’s not really “manufacturable” for us to be soldering those things on by hand.

Any potential benefit from the 64-bit processor (even though your base OS, Raspberian will continue to be 32-bit)?
It’s not necessarily the 64-bit that interests me, especially seeming as Rasbian will continue to be 32-bit for the time being. Compass could become more ambitious and I could build 64-bit packages, but I don’t see a lot of advantage in that vs. the time and effort it would take for me to maintain it.

The real difference here is that the RPi 3 is a Cortex-A53 based processor while the RPi2 is a Cortex-A7. Of particular interest is that the NEON SIMD execution units on the Cortex-A53 is twice as wide as on the Cortex-A7. Since SIMD can help out a lot with DSP tasks, that potentially make the RPi 3 much better at what we’re trying to do. Or, as the Raspberry Pi Foundation folks are saying “We chose the processor not because it was 64-bit, but because it was such a better 32-bit processor."

Mostly I'm curious if you plan to stick with the plan to use the Raspberry Pi 2 even though the Raspberry Pi 3 is out, same price, same form factor, same I/O?
It depends on what comes out in our testing. Since some folks are going to be worried about power consumption, if the RPi 3 takes significantly more juice than the RPi 2, we’ll consider staying with the older board. We also have to make sure we can completely turn off the WiFi and Bluetooth transceivers so that we don’t run into RFI issues with those being inside the same box as our 440MHz RF gear. If these tests turn out favorably, we’ll probably ship with RPi 3. If not, all the current testing has being going on RPi 2, and we’ll ship with what we know.

Looking forward to the BBQ or demo of a nearly-shipping UDRX-440 at MicroHAMS Digital Conference in a few weeks.
Hopefully I’ve answered some of your questions.

Thanks,

Steve N8GNJ

Re: Thumb DV Software

mikezingman@...
 

As a software developer I got EXACTLY what I wanted from the DV3000 and the ThumbDV.  They provide a  hardware platform  from which I can base my code.  I was well aware that the software from NWD was beta, and it makes no difference to me.

Now, users of my software are told up front, before they are even allowed to download it, that it is in development.  The contract between the developer and the user is simple: I will give you code with the understanding that it may be incomplete and has bugs.  You understand it is incomplete and will agree to use it and report  back issues you find.  Simple.  If that contract is not acceptable, then nothing is lost.

The DV3000/ThumbDV is far from the only product like this.  Every single board computer I  own is a work in progress.  The hardware is solid (usually) but the software is always a work in progress.  From device drivers to Linux to applications, it is a moving target.  

This is what I like to do.  It may not be your cup of tea.  For me any product in this space that does NOT evolve and improve is a dead product.  Why bother?  If I wanted an appliance I would buy it from ICOM/Kenwood/Yaesu.

If one stops to think about it, this is much more common than people may realize.

Look at your computer.  If it's not an Apple, Chromebook, or Microsoft Surface, you probably are running an Operating System and Applications that were not developed by the manufacturer.  If you have an issue with the software, the remedy is usually to contact the support network for the software, rather than the hardware manufacturer.

There are at least 4 different suppliers of software that use the ThumbDV.  Each of them have their own development and support cycle.  NW Digital Radio provides them basic integration information and in some cases contributes code (e.g. enhancements to AMBEserver), but the applications themselves remain under the umbrella of the various development companies or teams.

Incidentally, the manufacturers of similar products to the ThumbDV also use third party software.  One notable manufacturer also has their own application, in addition to 3rd parties, which has been in 'beta' for years at a time.

Don't get me wrong the product works however from a software support perspective I would caution users that this product is lacking.

Choices are a wonderful thing but not every choice is for everyone.    If you want to be part of testing or developing leading edge innovative solutions then products like the ThumbDV, MMDVM and others are great hardware.    If you want to just use something that plugs in and works then products like the DVDongle and DVAP with the software from the product designer and supported by the designer are for you.   

The 2 types should not be interchanged as it will only lead to frustration (in either case).

NW Digital Radio builds the ThumbDV Hardware.

Software is provided by 3rd party developers.  As stated on the resource page and the previous email, software support and releases come from those 3rd party developers, not NW Digital Radio.

The software that is out for the Thumb DV says Beta 3. I am curious as to why a finished product would still have Beta software. Where is the completed software if there is one???

Applications to use the ThumbDV™ and PiDV™ with your computer are distributed and supported by independent software developers. These applications are not distributed by NW Digital Radio. Support for these applications is provided by the respective authors.

Those developers determine their own release schedules.

Re: What about My Favorite Computer for the UDRX?

Bob Nielsen <n7xy@...>
 

Thanks John (and Jeremy).  I am getting to be too old to learn a new distro or anything really complex but hopefully can handle those changes (err, enhancements).  I'm sure I will have some more questions to ask at Microhams.

Bob,

From a user/administrator point of view, it's Raspbian/Jesse..

The Compass kernel is optimized for the UDRX and UDRC.  There are also some additional libraries, drivers, tools, and applications.

 

I have been unable to find anything about Compass Linux (only a framework app of that name).  Is there a website?

Now that we have switched to the RPi-2, we've had inquiries about using other single board computers.


The UDRX will ship fully assembled and tested with the RPi-2, but that doesn't mean you can't remove it and use a different SBC. Just be prepared to do a lot of work, with no guarantee of success, and no warranty for the result. Oh and you won't save any money either. because we won't ship units sans pi as there's no way to test it.


The RF Deck has a 40 pin socket and standoffs to mount the Pi upside down on the RF deck which makes it right side up when you flip the unit over. So if your MFC (My Favorite Computer) has the same form factor and pinout as the RPi-2 then you're half way there. If not then you'll have to figure out how to wire it up (see here for a suggestion).


Here's what you need to consider before "Hot-Rodding" your UDRX.


Hardware Interfaces Required:

  • I2C - Temperature and Gate Drive
  • UART with RTS CTS - Console Port or PiDV interface
  • I2S Bidirectional - IQ Transmit Receive (some boards are output only)
  • SPI with 5 Chip Selects - Configuration and ADC
  • 5V Operation

Software Issues:


The kernel package for NWDR’s Linux Distro, Compass Linux, a derivative of Raspbian, will be available in our Apt repository.  We will probably include  at least ircDDBGateway and APRX in Compass via redirects in our repository. Source will be available on GitHub.


The MODEMs, control software, and GUI Interface etc, written by NWDR, will be distributed as binaries in Compass Linux. The source will be available on GitHub.


Now I can't think of a good reason for actually doing this, beyond your personal desire. If anyone actually has something that the UDRX could do with the MFC that it couldn't do with a  Raspberry Pi-2, then by all means let us know.


Hope to see some of you at Microhams next month.
