Re: Dedicating one core to hard realtime tasks

In order to have full flexibility in designing machines (in this case 3D printer), you should have possibilities to change number of tasks, their types (interval, single, cyclic) and intervals (for Rasp. Pi 2 it can go from 100 microsec.). This can be done "on hot", without stopping progra...

Re: Razberry vs Aeon Labs Zstick

Hello ! PLC, that is based on IEC 61131-3 language specification, is quite good both for simple and very complex problems in measurement, automation and robotics. There are more producers of PLC run-tyme systems that are programable. From the practical point, that has influence on quality and speed ...
