Re: [Emc-users] Parallel Port Problems

I just looked at the manual for the Moschip 9865 and there isn't any mention of software select for the LPT signal pullups. It doesn't even mention any being internally available. Looking at the reference schematic they show that external 4.7K ohm resistors are to be used on all the LPT pins

I have been designing with x86 since the early 80's, ARM since the early 90's and several other architectures (Mips, Sparc, Alpha etc) over the years. I just don't get the recent attraction to moving the realtime out of the PC and onto ARM. It's lots of work for what actual benefit? This idea has
