Re: How to bring "down" PTT?

 

The PTT Output on DRAWS is an open collector NPN Transistor. It expects the Radio to have a pullup to Positive voltage, typically 5-12V.

If the PTT LED goes off then the SW has done its job.

Measure the voltage on PTT when yo power up, then again when you PTT and release.

Re: udrc-dkms fails to install after updating system/kernel

Basil Gunn
 

The udrc/draws tlv320aic32x4 driver is transitioning to a main line
linux kernel driver and will not be built using dkms in future kernels.

p.s. sgtm. then just device tree messing about.
Messing about is good.

Having our driver in the main line Linux kernel means there doesn't have
to be a 'special' kernel to support the udrc/draws hats. A standard
raspbian kernel will support those hats ... soon
(for soon = next_few_months).

Cross posting this from the udrc forum.
Not sure why you are asking your questions in main.

The tlv320aic3204 driver in the 4.19.42 kernel will NOT work
reliably. You need to stick with the 4.14.98 kernel until all of Anna's
patches work their way into the main stream kernel.

From Anna:

ALSA changed the API to some of their calls, and the old TLV320 driver
doesn’t have the calls. The new TLV320 driver is in the Raspbian
kernel, but it won’t work reliably until I get the final patch pushed
in the kernel.
Do NOT do an apt-get upgrade for a while until this gets fixed.
I have taken apt-get upgrade out of prog_refresh.sh script.

Re: How to bring "down" PTT?

Steve McGrane <temporarilyoffline@...>
 

The PTT line is 4.94v when the radio is on and the DRAWS/Pi is not

When the Pi comes on, the PTT line goes negative.

I have PTT line on draws connected to PTT line on Radio... but I'm thinking they both produce 5v and they should be connected in a crossover fashion?

Re: How to bring "down" PTT?

Ok, so now it works... magic I guess.

DRAWS => RADIO
AFOUT => MIC
PTT   => PTT
GND   => MIC GND
AFIN  => Rear Speaker TIP

Sep Non-insulated GND in DIN cable => GND in RJ-45 Bundle

I'm not really sure why this works, all I did was change around the ground alignment.  Before I was marrying all the grounds, now I have the MIC/MIC GND isolated to the DRAWS GND

If anybody can explain this, I'm all ears.

Pi Juice Hat

Steve McGrane <temporarilyoffline@...>
 

I didn't see this when searching the archives...

I have a bad habit of turning off my PS without shutting down the Pi... the thing is so quiet that I forget that its running.

Would the DRAWS supplying power to the Pi while the PiJuice hat sits in standby/UPS mode cause any kind of problems? 

Would the Pi select the best source or does one source take precedence over the other?

Hi Steve,

I saw that... and it might be in my future... or I might get another rig.

I got to the point where I MUST GET THIS WORKING... and now I have... but when the dust settles, this isn't the radio for a "go kit" since its only 2m, and you can't do voice without disconnecting digital and vice versa... we'll see...

Thanks for sending that over.

Cable For IC-7610 to DRAWS

Trying to find a cable to match the 8pin mini din on 7610 to 6pin din on DRAWS. Just not able to wire one myself, shake too much when soldering.

Hi Allen,

Re: Why Do I get a "Windows" type GUI after a reboot??

 

Not sure what you are looking for, Raspbian typically comes up in either a GUI (with the default being the Pixel desktop) or a command line interface.

You can select which one it uses by using raspi-config

DRAWS Video #4

Steve McGrane <temporarilyoffline@...>
 

Its been a while, but now that my radio is back from factory service, I got the kick in the pants I needed to make another video.

This video is all about how to make a bootable backup of your SD card in case mayhem strikes.

Take a look and let me know what you think by clicking like or dislike:


Next up will be a JS8 Video, Stay Tuned!

I haven't heard anything since on the subject.  I know that last summer Jonathan had added the UDRC but I don't know if it made it into the main stream code or stayed 'experimental'. All I can state at this point is that it hasn't made it into Pi-Star yet.

Audio Debug?

Steve McGrane <temporarilyoffline@...>
 

I'm not getting what I think would be the right audio in/out from the DRAWS.  I've tried a second cable and the second port.  I get some input, but not 100% and I get no output in FT8 or JS8Call.  When I'm in FLDIGI, I get no waterfall, but I can hit the tuner function and it will transmit a tuning sound and my remote signal strength meter registers TX as well.

Is there anyway to run a command and get some test output?

Regards,
- Steve

Re: Audio Debug?

To output an audio tone on either the left or right draws connector use
the measure_deviate.sh script. Documentation here:
https://github.com/nwdigitalradio/n7nix/tree/master/deviation

Script here:
n7nix/deviation/measure_deviate.sh

Also run:
alsa-show.sh

Do these settings match the radio you are using?
ie. did you use John's web based draws-manager?

I had to re-run my setalsa-ft891.sh script and that reset the levels to something working.  Been a while since I touched that.

Re: DRAWS Video #4

Michael Starling
 

Steve,

Have enjoyed your videos.  Am a computer guy but not much UNIX background.  Have gotten a 3b+ up and running with an ICOM 7300.

Wondering what your opinion is of the value of the DRAWS HAT is with that radio given that it already has the equivalent of a signal link built in.

Re: New to Linux/Unix? #linux #commands

Michael Starling
 

Thank you!

Re: DRAWS Video #4

Ryan W Leathers
 

Michael asked the question about the usefulness of the DRAWS with a rig like the IC-7300.

The DRAWS is much more than a sound card and digital modes interface.  It is a convenient way to get highly accurate GPS position, clock, run a variety of interesting applications for rig control and digital modes without a bulky PC or laptop, and it does all this using the same 12v systems you already have for portable / mobile use.

The question for me is not about duplication of signaling style capabilities. Rather it is whether or not one plans on mobile / portable operation. This is where features like the GPS, small form factor, and power really put the DRAWS in a class of its own, at least in my opinion.

There are other ways to run digital modes on Linux in the shack, so DRAWS is just another option there. But in the field it's a different story. Nothing else comes close.
