Re: [CAD_CAM_EDM_DRO] Re: UCMI Interface

Hi Matt:

My understanding is that the APIC was disabled on earlier motherboards, but
is now universally enabled on all future and present chipsets. Some
motherboards do disable it, but only via software.It can be turned on very
easily by an application. What makes it attractive to me is that nothing
else seems to use it. Master5 has problems with some motherboards due to
their doing funny things with the int8 interface, but an APIC should be able
to be programmed to be very fast and asyncronous for all axis. That should
give resolutions down to uS levels. I think I'll have to write some test
routines to see how it works. Maybe I can upload them and ask people to try
the test applications just to see what resolution would be available and how
many people could use them.
