Re: "dumb box" project[s]

Alan,

Sorry, this is the corrected link for the "dumb box" chip write
up. It's no longer on his "news" page:

http://www.rutex.com/rt900_1.pdf

Here's the one on the box itself, which isn't as detailed:

http://www.rutex.com/900000_1.pdf

For those who don't feel like clicking around to see what's going
on, here are the basic specs for the "dumb box":

115 kB RS232 interface to PC serial port
32 bit position resolution
3 step and direction axes
16 digital IO lines (8 in, 8 out)
2 analog inputs, 2 PWM outputs

Not a bad little device. One drawback is that it expects a full
serial packet every 6 mS, so the the PC is still more or less in the
timing loop during motion.

A major positive is that it's PIC driven, and the hex image of the
chip's program can be downloaded and programmed by anyone - no
exclusivity over the hardware.

Like I said, an option to drive this unit thru TurboCNC is still in
the pipeline. Looks like there a good oppurtunity for a Windows
programmer to step to the plate here and offer something for that OS
as well...

PS: To answer your other question, yes, G92 will be in the 3.0g
version of my program.
