In the direwolf configuration
Channel 0 is the left DIN connector
Channel 1 is the right DIN connector

Xastir can be loaded and access the gpsd at localhost and the modem via AGWPE interface.

Re: DRAWS downloadable Image? #setup #compassimage #draws #earlyadopters

 

Hi August,

The holidays caught us and we don't have the final alpha image ready yet.  However, you can get your DRAWS running with just a bit of work.

First, download http://archive.compasslinux.org/images/image_2018-11-18-compass.zip
Uncompress the image with a zip program
Burn it to a SD card using Etcher or other image copying program (dd on Linux for example)
Boot the image and edit /boot/config.txt and change the last line from dtoverlay=udrc to dtoverlay=draws
Save and reboot.

You should now have an image for DRAWS.

Verifying DRAWS and UDRC Hardware

When using Compass Linux, the command aplay -L will list the sound devices including your DRAWS or UDRC (DRAWS may show UDRC, the sound subsystem is the same).  You can also find the device under /sys/firmware/devicetree/base/hat by looking at the contents of the product file and vendor file.  On DRAWS, the GPS serial port is at /dev/ttySC0 and pulse per second device is at /dev/pps0.

Get the GPS running, if you have an antenna attached - see wiki page

Install chrony and direwolf
sudo apt-get install chrony direwolf

The short answer is Yes.

Starting with delivery of the DRAWS HAT, a downloadable image will be available to run the DRAWS workstation.  It will contain the current version of Raspbian (Stretch) including preloaded DRAWS HAT driver and a selection of applications that have been compiled for and tested on the DRAWS platform.

I now have my DRAWS HAT delivered, where do I find this downloadable image?

Thanks,

Hi Brian,

Nice to see you too.

As for the Draws RPi hat, I was actually trying to avoid VNC because you need another computer or your mobile phone to run VNC.
Really I would like to use only one computer when portable (i.e. only the RPi or my mobile phone) not another computer as well in order to control the RPi.
If I have to use a mobile phone or tablet I can use a Wolphilink Interface with my mobile phone or 8 inch Winbook, so the RPi is not needed and I can save a lot of battery power this way!
Battery power is not to be wasted while portable!

At least this is the way I would like it done! Others have their own ideas and are respected!

Thanks for the reply!

Demetre,

It is so very cool to run into you again after 20 years.  Regarding your description below, if you don’t mind I’d like to tell you how I have done this with my HF portable rig.

I never touch my Pi or radio at all while operating digital modes.  Instead I host a WiFi hotspot on the Pi that is always running and hidden away in my rig backpack.   I connect to WiFi with my phone and bring up the interface either with http, ssh or VNC tunnelled over ssh (depending on the app).

For example:  
Pat : http, or ssh
Arim/ardop: ssh (works really well)
Fldigi: VNC or ssh+nc to the telnet port.  I also have a script that starts fldigi in wefax mode and tunes the rig for hands free operation.
Flrig: VNC
Hamlib scripts to automatically configure the rig for each mode: ssh or VNC with .desktop icons
Direwolf: ssh to stop and start
YACC: VNC

A typical operation sequence would be.

1) connect to WiFi
2) connect to Pi using ssh
3) run script radio_on.sh
4) run script direwolf30m.sh
5) disconnect

This could be automated with a webpage, but this works just as well for me, and for most operations it is as easy to use as sending an email with your phone.

The way it is now, you need so many cables and this is far from suitable for portable operating!

I hope the makers will think about it in the next version.
