the cooling fans are working, I see the GREEN LED on the Pi illuminated continually, and do not

see the RED LED illuminate at all.

why would that be? the Pi worked / works perfectly when powered from its USB power port.

Thank you

Re: 12V DC draws hat supply?

Gwen Patton
 

I would answer if I had one, John. I have my Draws hat, but I haven't tried putting it on a Pi yet. I've been waiting for the bugs to get squished first. Otherwise, I'd suggest that maybe responses over a weekend are probably going to take a while. Maybe the guys will chime in now that it's working hours.

Re: How do I install JUST the draws drivers please?

Basil Gunn
 

I now need to ONLY INSTALL draws lib components to utilise the audio
codec and I/O
The draws driver is part of mainline Linux IF you are using a current
kernel.

See "Make your own Raspberry Pi image" here:
https://github.com/nwdigitalradio/n7nix/blob/master/docs/DRAWS_CONFIG.md#make-your-own-raspberry-pi-image

Can I please have some advice on how to go about that.

How do I install JUST the draws drivers please?

John McRae
 

I am finally having some success with my Pi 4b

I ended up not using the NWDIG .img

So, having gotten fldigi working ok, Including CAT ctrl

I now need to ONLY INSTALL draws lib components to utilise the audio codec and I/O

Can I please have some advice on how to go about that.

Really appreciated in anticipation.

You are looking at the wrong group files location. You are in group main the
files are in group udrc. If you just click on the link John gave you:

it will bring up the schematic.

It looks like you went to the 'main' group for nw-digital-radio -- this file is in the files section of the udrc subgroup.  If your browser is logged into groups.io, you should just be able to click on the link.

There is no CAT control on the DRAWS hat. The mini DINS are for the input/output of digital audio. You can attach two radios hence two connectors. CAT is done by a USB to CAT cable for your radio. You need to provide that cable.

I was totally lost until I found a great series of videos starting at https://youtu.be/u6wz2kZJ5Vo

These five videos take you calmly through setup step by step. That guy deserves a medal.

All the best

Related-ish, does the "Accessory Connector HDR-4X2M" connector have another standardized name if I wanted to source a connector for it? I currently have female header jumpers connected to it, but I'd like something more robust.

As I do not need presently that Draws-manager I will not take your time and will wait for a fresh install when I get the opportunity or need to do so. Everything else is doing well presently.

Thanks both for your help.

Re: PRECIPITOUS EDUCATIONAL ARC

Basil Gunn
 

I just burned and booted an nwdr15.img and draws-manager ran and worked
in both remote & local browser without doing anything further.

I then:

cd
cd n7nix
git pull
cd config
./bin_refresh.sh

sudo su
apt-get update
apt-get dist-upgrade

and after a reboot draws-manager again ran fine.

If you did something other than the above or attempted to install
draws-manager when it is already installed then that possibly could be
your problem.
