You are correct J. Ray, thank you. It may join my .sig.

Re: [Emc-users] chart of arrays

[Nicklas SB Karlsson]

Den 2021-04-28 kl. 06:09, skrev Stuart Stevenson:

Gentlemen,
   Has anyone developed or printed a chart of arrays to use for
visualization during LinuxCNC development?


Not sure what you want. Type hierarchy, call hierarchy for static calls 
and class hierarchy is probably what is possible to do. Sometimes a 
diagram with signal path may give a good picture of the software, this 
is the case  for the configuration, it however have limitations for 
sequential program flow.



If I remember correctly a graphical visualization of structural VHDL 
give a really good picture of the connections between blocks while more 
conventional text is used within blocks. Think VHDL have quite much in 
common with what happen in configuration file.



Wrote PLC program a few weeks ago. Graphical state machine, CFC blocks 
within states and ordinary sequential programming within block which is 
Structured text for blocks. Rather satisfied with this solution. Have 
not yet seen software for state machines I am happy with, ideally I want 
output only to depend on current, outputs should also be well defined 
for all states, have been able to do this in ordinary text based 
programming language by using array/vector of structures with lookup table.

Re: [Emc-users] reducing rigid tapping overshoot

[John Dammeyer]

The idea behind Lazarus is write once, compile anywhere.  So I've been working 
on a few projects that unfortunately make that philosophy a bit of a stretch 
(polite term).  Programs written and compiled under windows didn't even compile 
properly on a Pi or Beagle.
 
The thing about fpcupdeluxe is that it's an interface that lets you choose a 
specific version of both FPC and Lazarus.
For example, "sudo apt install lazarus" gets version 1.6.7 I believe.
 
But when you install it for a windows PC you get 2.0.10.  With the fpcupdeluxe 
I was able to get and build that specific version for both the Beagle and the 
Pi.  After that, since the libraries now matched, the applications compiled and 
ran.  Although still not exactly the same.
 
Graphical components appear to have an issue.  What works on Windows doesn't 
work correctly on the Beagle or Pi.  So I tried it on the LinuxCNC pc with rev 
1.6.7.  Same problem there so it's an issue with an object descended from 
TGraphicControl.  
TjdSevenSegDisplay = class(TGraphicControl)...
 
Note in the photo when the component rectangle on which the segments are placed 
is dragged away from the 0,0 corner the segments don't come with nor do they 
resize correctly when the rectangle is expanded.  On windows it works 
perfectly.  On Linux it doesn't.  The 6 digit display doesn’t have the problem 
so I'm on track for trying to figure out what's different at the base level of 
the component design.
 
cid:image001.png@01D73BB9.185437C0
 
Anyway, that's why I want to be able to install the same version on full sized 
Linux system since I can't break the component on the WIN-7 or WIN-10 PCs and 
it takes way to long using a Pi or Beagle as the working desktop PC to do 
anything.
 
And in the long run one of my goals is to develop some graphical based tools 
that run on Windows and LinuxCNC for machine control with CAN bus.  That the 
sockets.pp interface for Lazarus is behind the sockets.c is another issue with 
socketCAN not yet supported by Lazarus.

I'm not sure you need any of these.  Most Linux installs 
have fpc in their software library, it can be installed with 
something like :


sudo apt install fpc

sudo dpkg -i fpc

I don't even know what a chart of arrays is.
