![]() When I define kernel as 'works' means that it compiles and runs linuxcnc and will drive I/O Even the realtime kernels do not give great performance and this means a fast basethread and software step generation is not really possible. RTAI does not work, probably never will. ![]() Standard linux kernel with preempt and posix threads works, but maynot guarantee timing schedulesÄue to the poor realtime performance I/O requires special consideration as software stepgen is probably not possible unless improvements can be made in the realtime kernels.Possible ways of constant step pulses and reducing load on processor GPIO direct by processor (limited by the base thread time).Off board I/O hardware based on one to the serial buses(which have independant hardware buffers, but the buffering does not guarantee timing so intelligent mcu must be used ).
