I think a clearly separated real time motion system with the flexibility and extensibility of a HAL based approach would be of great use to many applications (we have customers that could use it now but a linux HMI is often a sticking point) The requirements for running a real time OS and sophisticated motion control hardware/firmware has been reduced to only a few chips (TI Sitara (= beagebone) or Xilinx ZYNQ for example). The ability to run just the real time portion of motion on embedded systems like th eabove would both increase the range of hardware that LinuxCNC supports, increase the performance of LinuxCNC by using hardware that is optimized for real time performance, and generate a very flexible motion toolkit at the same time. > > > > >> >> >> -- >> John Kasunich >> [email protected] >> >> ------------------------------------------------------------------------------ >> Everyone hates slow websites.
