Humm, I thought I had laid it out in prior messages, maybe not clear enough. My mind has been known to skip a whole paragraph when its occupied by the actual typing. I am not a touch typist with my fingers running automatically in pace with my thoughts. What I wanted was a binary counter, whose individual bitN outputs could drive the selN lines of a mux16, thereby selecting the gain to be applied to the jogwheel output. My plan is to use the nibble sized output, plus a sign bit, so I theoretically could have 16 speeds in either direction, with a spst button right beside the dial to switch from driving motions jog input, to moving the gain control counter one step per dial click when the button is pushed, this to scale the counts obtained when the button isn't pushed. Using a mux16 to select the gain multiplier on a 1,2,5 repeating sequence, allowing both very fine response of one motor microstep step per detent of the dial, up to faster than the machine can move with relatively few "clicks" of the dial wheel. I plan to display the state of the speed settings with a pair of hbars in pyvcp. But that bit of pyvcp/xml hasn't been written yet. Last night, with only one eye open, I read lots more manpages, and it looks like I might be able to achieve this 4 bit mux16 address with bitslice and some limiting to keep the value of a u32 in-range, using similar logic to inc/dec the u32. Write & test when I've input enough coffee to get both eyes open at the same time. I just woke up, got us each a cuppa, and I'll see what my lady, recovering from a hip replacement 3 weeks ago tomorrow, wants for breakfast, next, while a new pot is making, this was yesterdays cold and nuked leftovers. She is getting around on a walker pretty good now, but there's still a bunch of distracting honeydo's a day too. I don't recommend getting old Andy, it is not all its promoted to be by AARP. Avoid it if you can. But its catching up with us, darnit. ;-/ Thanks Andy. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
