QTPlasmaC - QTVCP error

Category: Plasmac

That is what I do mostly Rob but there are many users that are not capable of doing their own compile.
When I setup a machine for a customer or user, I use the buildbots to make it easy for them to stay current. MX Linux provides an easy way to update. This suits most users and therefore the buildbots are really necessary.

I am looking at setting up a private repository where I can place the compiled DEBS on a weekly basis. I will point their Synaptic Manager to the private repository to do automatic updates. I am just having a hard time to get the files signed in the correct manner for apt to recognize them as a proper repository.

Not quite as convenient but if this pull request was committed, making Debs is very trivial as it uses the Debian build environment to get the dependencies so it becomes a 3-4 line process.
github.com/LinuxCNC/linuxcnc/pull/2647
eg as I tested: in the comments.
[code]$ cd linuxcnc-dev
$ ./debian/configure
$ sudo apt-get build-dep .
$ DEB_BUILD_OPTIONS=nocheck dpkg-buildpackage -uc -B
[/code]

Not quite what I was looking for but something like this. SOme have stops that let you limit the number of positions

In the US, this is all Digikey has that's coded for hexadecimal. My own personal lack of vocabulary for searching is also something I hope to improve as part of this conversation.

Me too! so I am hesitant to make a recommendation for that reason but I think that a 3 pole or 4 pole 12 position rotary switch also does what we want. eg decodes a position to a bit map on the poles.

As an aside, I am also a little confused why PCW suggested 00, 11, 01, 10, instead of 00, 01, 10, 11. It seems more logical to me to order it like legit binary, and it's not like it's harder to connect it this way.

The 4  --> 2 diode encoder circuit I posted is in binary order but you need to consider
that the 7I73 inputs have pullup resistors so are high when unconnected and low when
grounded through a diode so:

SWITCH POSITION
0  Grounds inputs 0,1 with CR1 and CR2 = 00b = 0d
1  Grounds input 1 with CR3 = 01b = 1d
2  Grounds input 0 with CR4 = 10b = 2d
3 No connect so = 11b = 3d

 

Can you recommend a source of information that can decode what you just said?
