If synchronization is needed, how about writing a MIDI "instrument" to "play" the motors? MIDI has built-in synchronization, and all you need to do is specifiy the timing of events.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

I offered the guy this: GitHub - codewitch-honey-crisis/htcw_ramp[^] which is a simple class that allows you to ramp between two values at a given step and time interval.
I used it to control multiple steppers of the exact kind he is using for an HVAC system.
He told me that was "wrong" and seemed pretty upset with me for even trying to help.

I offered him a simpler solution which worked for me when I faced a similar problem with an HVAC system I was tasked with writing firmware for.

Are you over thirty?? If so, in this industry, you are old. 
Once you get past fifty, you become ancient.  You now have the right to be crotchety.
Me? I am over seventy and thus, I am a living fossil!! At this point, crotchety defines you. ![Java | [Coffee]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/coffee.gif)

I'm old approaching ancient.
What I've heard is people on average hit their intellectual peak in their 40s and then start losing some mental agility with age.
I'm right about peaked if that's true, which sort of worries me because there are things I want to understand but can't yet. I have however, had a lot of breakthroughs in the field in my 40s - primarily centered around getting into embedded, and systems stuff again (first time working in constrained environments since the 1980s and '90s)
But also if it's true it means the industry is missing out on tapping the full potential of developers.

This has been true for longer than either of us has been alive, and I'm 62. Developers and engineers in general are sufficiently different in how they think that most people around us either can't understand us or resent the fact that we view problems as having a solution.

This is true in many technical fields. The advancement path in many companies forces people to "advance" into management. The type of people who want to be in management, often from sales or marketing backgrounds, cannot understand why some people do not want to be in line (as opposed to project) management -- they see this as a personality defect.  Thus, it is move up or move out. They cannot see the value of paying for experience.

honey the codewitch wrote: Back when I learned to code solving problems like this meant you were a coder.
At least for me when it was always 'do it myself' the following was true
- There was a lot less available
- I didn't know how to find it.
- What I could find cost money. Sometimes quite a lot.
- I figured no one else could have possibly been doing the same as what I was.
honey the codewitch wrote: Now it seems like people just expect that there's a library that will solve whatever problem they're after solving
Now it is many years later
- Of course someone has already tried to do this before.
- There are a lot better ways to find it.
- It probably costs nothing or very little (at least compared to long ago.)
- My time is better spent evaluating existing solutions and gluing pieces together versus trying to implement everything from scratch.
A lot of the above comes from realizing that throwing code is just a tool and not genius. What really matters is that the company sells something so that I keep getting paid.

For some reason today, I started wondering if anyone (companies specifically) was still using Unix -- any distro from the past which was still considered Unix & being used at a company.
I was assuming that Linux has killed Unix installations and forward development.
I found this: Unix is dead. Long live Unix! • The Register[^]
What is your experience with this? Any company you are working for that is using a Unix distro?
Just curious.
Oh, and I wrote this from my new Mac PowerBook M3 (36GB ram) and maybe macOS is considered Unix?
Not sure, but I'm reading this article now: https://www.howtogeek.com/441599/is-macos-unix-and-what-does-that-mean/[^]
EDIT 2
I thought maybe BSD was still around, but looks like it isn't: Berkeley Software Distribution - Wikipedia[^]
EDIT 3
Very interesting (from that 1st article above):
Quote: There are two standards that certify UNIX: POSIX and Single UNIX Specification (SUS). SUS is a superset of POSIX. So, something can be POSIX compliant, but that doesn't make it UNIX. However, if something is SUS-compliant, it's a UNIX.

The only area where I used UNIX was at Uni, everywhere else it been Windows or Linux... Too big, too costly, neat Keyboard with the short cuts as Keys.
|
|
|
|

Yeah that makes sense, since I know it was originally created for "big metal" like the PDP-11 etc.
Thanks for sharing.

Also an oddity between Windows and UNIX is the memory in Intel is 64K chunks, UNIX is flat no divisions & so is Linux which confused the ![Elephant | [mastadon]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/elephant.gif) out of me trying to read a value to see if a card was present, not to sure about the PDP series might have had flat memory and does the Mac, I'm guessing the Apple][ had 64K chunks as that was a common value for memory (Commodre 64 etc)

Wikipedia says that HP-UX had a release last May and that IBM-AIX had a release in November, so there must still be some people using Unix, somewhere. As for PC level OS, Linux has pretty much sucked up all the oxygen, but Open/Free/Net BSD are still out there and have a following. SCO is still available too, it seems, but since the Linux copyright debacle, I don't think it's too popular. I don't even know who owns it, anymore.
Side note: My first professional job was working with MS Xenix on a Tandy 6000 (8MHz M68K, 1MB Ram, 15MB HD). Today, it's hard to imagine that you could do anything useful with those specs. That it could be used in a multi-user environment (some of our clients had 4 or more serial terminals) is just mind-blowing. Today, I wonder if you could get a stripped down linux kernel to fit, never mind getting 2 or 3 user shells up and running.

The only place I used UNIX was on a Telephone switch that I was writing Call center software for.
I learned just enough to operate the switch because no one else in the company knew anything about it and didn't want to learn.

Didn't see any mention of QNX (Unix-like) which is apparently still alive.
|
|
|
|
|
Interesting...I looked up QNX on wikipedia -- that one falls into an odd place where it might meet requirements, but might not be exactly unix. I'm just wondering if any of the "original" unixes are out there running. Aren't there companies with "big metal" running still? i mean companies are still running COBOL and that flight system that is ancient so I thought maybe "real" unix might still be out there. ???

I haven't heard anyone talk about QNX in forever! Kinda glad it's still around.

QNX is the only "Unix" I've touched, and I had very little interaction with it.
The company I was with in the 90s used it for a point-of-sale system, but I was working on the back office systems (in OpenVMS).

While I don't use it myself, I am willing to bet it's fairly common in embedded dev just because virtually all the tools are unix-centric.
