Isn't it more that real time kernels are necessary period? The number crunching itself can't be that problematic...I just upgraded an old Anilam mill controller

Isn't it more that real time kernels are necessary period? The number crunching itself can't be that problematic...I just upgraded an old Anilam mill controller that ran 3 axes. It was running on a 386.
The new encoders on the servos are way better, but the replacement modern hardware is also way better.
I think in both cases (especially the upgrade), the event handlers and drivers are all done in separate, dedicated hardware
- defterGoose 7y agoWell, you can run the simulation and such without it, but for doing any real work, yes they are necessary. That was kind of my point though: you could in theory put one of those kernels on an RPi or something (barring compatibility issues with the chipset), but you'd probably still be lacking the proper IO hardware, etc.
- Causality1 7y agoAbsolutely agree. Modern operating systems are utter beasts when it comes to complexity and are far less predictable than simpler solutions. There are reasons microcontrollers are still everywhere.
