Interesting.  Hadn't thought to use verbose.  What's even more interesting is 
my parallel port doesn't show up in the list.

Re: [Emc-users] Pi4 LinuxCNC

2021-05-04 Thread Ralph Stirling 
The only 64 bit OS for Rpi is still in bera, so you would have to work hard to 
find it and install it.  I dug around last week to verify that.  The "v7l" in 
the image name and in uname -a is for 32bit.

So if it says ELF 32-bit LSB executable then I'm running the 32 bit version?

The newer version of the Pi OS with uname -a says Linux raspberrypi 5.10.17-v71

The LinuxCNC version was 4.7 I think.  Not running it at the moment.

To get the port addresses, you need lspci -v

So if it says ELF 32-bit LSB executable then I'm running the 32 bit version?

The newer version of the Pi OS with uname -a says Linux raspberrypi 5.10.17-v71

The LinuxCNC version was 4.7 I think.  Not running it at the moment.

I thought I'd try that on my LinuxCNC system.  With or without sudo it does 
print a list of all the devices but it doesn't tell me the actual port address 
of the standard port on the machine (0x378) which I know because when I dual 
boot it into MACH3 instead of Linux and move the parallel port cable from the 
MESA to the back of the machine it works with that address.

I haven't run it with the back of the machine in Linux for a while but the hal 
file uses cfg=0 for the standard port and when I had a second PCI card 
installed it was cfg=0x2000

On some installs, for some reason, lspci is not listed in 
the right library, and you have to use

/sbin/lspci

I have no idea why, might be a Debian idea.

You DO have to run it under sudo or with privileges to see

of device type will show without sudo.

I wouldn't recommend using Wheezy any more, though, it is well and
truly out of support.

With the Buster install you could try "sudo apt-get install pciutils"

Is there another good way to find the ports?

I guess we're in the same try it and see campsite then, Jon.

Although hooking my new scope up to the pwmgen's output going to the BTS 
7960 board was nice and educational.  Its 10" screen can be seen and 
read easily from several feet away. 350 megahertz bandwidth, 4 color 
trace sampler. Siglint's best.  Sure made it easy to see what the pwmgen 
was doing. And thinking outside the box a bit, I tapped into hal and 
sent some of it to spare i/o, also much faster than the halscope but 
broken by the servo thread time quantization. Too bad the 5i25/7i76 
doesn't have more analog outputs though. Being able to export the analog 
following error to a huge display sure would be nice. you could see it 
in real time without all the bs of having to switch focus with the mouse 
to exersize it, that is a certified PITA that leads to lots of mistakes 
because the nouse focus has to be shifted so many times to do it. 
Your "go" click winds up destroying you halscope setup, so you have to 
wait for the thing to finish, set it up again to look at what you 
intended to see, then remember that you must waste a click to get the go 
focus back to the mdi line and away from the halscope. 

Now if linux had a focus follows mouse that actually worked.. But 
I've not found that particular magic twanger yet. You could do it 15 
years ago, why not now?

Thanks Jon.
