I think that needs three states. The software encoder has "latch" inputs and outputs, possibly for this purpose (they exist but the docs say nothing: http://linuxcnc.org/docs/2.7/html/man/man9/encoder.9.html The Mesa encoder goes one step further, the latch inputs and outputs are created but not even documented: https://github.com/LinuxCNC/linuxcnc/blob/master/src/hal/drivers/mesa-hostmot2/encoder.c#L461 -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
