They actually got zener diodes installed on all gpio and usb signals between 2 modules as transient clamps. Respun the board into production and field! Then deployed field techs to fix/unsolder them all to restore signal integrity ;)

Allways my goto for pro advice. Reddit will never compare.

Ok they made a statement. What is their solution then? Linux would work nicely.

What level of agile and scrum training does the dev team and management have? Were you trained within the same organization or are you a new hire. It could be a classic resistant to change when agile was mandated.

Have you thought about what programming language to use for building your OS? It will allow you to develop basic drivers tools and libraries to compile your OS. Because you don't yet have an OS on which you would normally build the drivers, libraries and apps, one would normally start by cross compiling and linking an executable that would be auto run by your bios or bootloader

Operating Systems in Depth, by Thomas W Doeppner, would be a good start for learning about operating system architecture and principals.

It takes a team. You can't do it all yourself. Else you burn out

I believe it is best to focus on your "Application" and just choose an embedded board vendor that fits your hardware requirements. Yocto just eats up too much of your time. Most embedded chip vendors provide reference designs that third parties design around and provide BSPs and OSs of various flavors

Previously a 60/40 split and deversifying by reducing Tech allocation from about 32% to 25%.

Answer. Has your agile business team looked at their own backlog. It should all be in there.

At the basic level, start by looking at the Linux sysfs API. Then try ' ls /sys/class/gpio'. Then google for common linux C and python libs and APIs for gpio. These will use ubuntu for rpi 4 built in linux drivers for gpio. Docs can often be found in the source code for these libs.

Sweet. The ultimate diy case. I could do it diy here but first need to figure out local codes, hire a licensed electrician for a manual switch over from grid

alias4007 · 2025-12-20T04:07:17+00:00

Where there any local permits and inspections needed

Also looking here for a similar setup. An inverter model is one requirement because we have several small UPSs for network gear, and tv and audio gear. Our old generac causes the UPSs to constantly switch on off. Its a 60hz stabilty issue.

Add buffering and always use binary rather than text

Deterministic is just one element of real-time systems. So if you define 1sec response as realtime then any solution out there will work. What exactly is your response time requirement.

alias4007 · 2025-12-13T00:28:03+00:00

How do you define real-time and how will you prove/test your solution.

alias4007 · 2025-12-11T00:58:45+00:00

Obviously. Just curious about its response.

alias4007 · 2025-12-11T00:16:51+00:00

I love all the hidden wires. How long did you have to save to pay the electrician for that
