Re: [Elecraft] S: Re: KX3/PX3 Linux Utilities for Raspberry Pi?

[lstavenhagen]

Ah, never mind, my mistake. I've never used the Linux version at all, so I
know even less about that one lol. But yes there's much less of an excuse
there, since 64bit support has been in the Intel-based gcc tools forever

Windows?  I thought we were talking about Linux!  At least that is what
I inferred from the thread.

I was specifically referring to the present Linux utility tarball on the
Elecraft download page.  It is for the i386 architecture only.

That's what I was referring to.

Yes, it does have limitations that are discussed elsewhere.

Hi Nate,
I wasn't aware the Windows version was still on x86, but I'm not terribly
surprised. It might look trivial from the outside looking in, but MS charges
a fortune for their dev tools. So maybe Elecraft isn't going to spring for
the X64/amd64 cross-compilers and libs until x86 emulation finally drops off
all the old Windows variants. And there may be portability issues that would
require extra work that we don't know about too.

Not quite like gcc-based toolchains where you can find a backend for almost
any processor out there and it's free too 

Still looks like the Rasperry Pi is an interesting device...

At this time not even amd64 builds of the Elecraft tools have been made
available so I run them in a i386 VirtualBox instance of Debian Jessie
on the odd occasion I need to use them.

They're not usually installed by default but are available via the
package manager of choice (in my case that is Aptitude).  As I recall
the build-essentials package is a meta package that includes most common
build tools as dependencies.

> How's the Python support?

The Pi Foundation has made sure that the Python support is very good.

Maybe after it settles down a bit more Elecraft might look at supporting it?
I wish I had the spare brain cycles to play with one of these, looks like a
lot of bang/buck

Do the linux distros for it come with the dev. toolchains like GCC in them
(I would imagine it's now matured past having to cross-compile binaries for
it on PCs) ? How's the Python support?

Oh well, back to my K2 build!

Re: [Elecraft] S: Re: KX3/PX3 Linux Utilities for Raspberry Pi?

[Andy McMullin]

Hi John (et al),

For my display with this one I’m using the original HDMI-Pi screen — the 
original was not a touch screen but measures 9 inches on the visible diagonal — 
with its own PSU (12v into it drives the screen and supplies 5v for the Pi) and 
case. The bad news is that, although the case looks lovely being made of 
coloured plastic, it seems to be totally transparent to anything from the 
Pi/screen that might cause any sort of QRM. Oh well!

The case design is OK but it leaves the USB pointing downwards with little 
space for the KX3’s USB lump. However, a pair of right-angle USB 3 adapters 
from Amazon fixed that one for me. Being a Pi-3 I use the internal WiFi for 
internet and the rest, leaving one USB spare when I have one for wireless 
keyboard/mouse, one for the the KX3 and one for a Signalink-USB as the 
soundcard.

I’m using the Ubuntu Mate version of the OS on the Pi and the only issue I 
have/had with WSJT-X is that it sometimes fails to start at all unless it’s run 
with administrator privileges. But that’s only happened since the last library 
update so it’s obviously a permissions thing I’ll need to fix "one day”. As you 
might guess, at the moment I need the internet for the RTC synchronisation for 
JT65/JT9. However, I’ve ordered an add-on board that includes a better RTC as 
well as UPS functionality. 

I have another Pi (a Pi 2) with a 5-inch touch-screen from Amazon (actually a 
company called Waveshare) BUT the screen has its own special drivers which 
don’t seem to be available for versions of the Pi OS since last May. They’ve 
made pre-built OS images with all the stuff included available for download but 
the images are “ancient” (and won’t work right with a Pi 3) and include a load 
of stuff I don’t want. The company don’t seem to want to respond to requests 
for driver information either so I’d avoid that particular screen is you can.

Anyway, I hope your experimenting goes well too. Would you vote for the KX3 
utility available for the Raspberry Pi?

— 
Regards
Andy, G8TQH
