Boggles the mind so I did, and am doing some testing. Show pins appears to be accurate for computer outputs to named functions, fails for outputs to the machinery, for that I have to use dmesg For outputs, the dmesg and the halscope selector both appear to be correct, I just fired up lcnc and ran the halscope, no signals from the machine are connected to anything as I am waiting on some 5 pin connectors, and the 8 stepgen sigs, step(4) & dir(4) signals are indeed on 5i25 gpio.000 thru gpio.007, so dmesg isn't lying to me and I've got to move every i/o of that group I am using to some other gpio. gpio's that show pin says are bi-dir. Ack show pins, that is gpio.008, 009, 012, 013 that feeds p3. show-pins says they (5i25.0.gpio.000 thru gpio.007) as uncommitted but they are in fact the outputs of the stepgens, and unavailable for anything else. The giveaway in the show-pins list is that particular gpio has no bit-IN line. Since 5i25 gpio's are all bi-dir, if show-pins only shows 2 lines of input from the computer, both called bit OUT, but there's no bit IN line, then its used by the 7i76. For something else. Basicly, forget about using the first 16 gpio's that feed P3. What I'm trying to do is make up a list that does tell me whats usable, and what shows in show pin that has already been taken by something else show pin doesn't know about since it hasn't processed the whole 761 lines of the hal file. So I am surveying to see whats left when I find a clash that for some reason, is not an error when hal parses it at startup. So I am trying to see whats left in the 5i25 from gpio.016 to gpio.033. Thats all on 5i25-P2, looking at a std bob, so the 7i76 hasn't a clue its there. And using a wagon load of paper keeping my work sheets up to date. I would like to be able to walk thru a .hal printout, and everytime I come across a clash that hal doesn't detect, to know what the heck I am doing when I move a signal to a different gpio to solve a tug of war each time I have to. And that correction then generates another 18 page .hal printout. And a page of dmeg as I add comments, plus 5 or 6 pages of show pins as I add comments to it as to what that pin is actually doing. ATM I have 7 tally switches to configure, and 9 more outputs, only 4 of which I've found and verified are working as far as seeing them at the outputs of these 3 cards. Next is finding if the pwmgen signals are on p2 where they apparently were moved to by the 5i25_7i76_7i78 firmware I've put in the 5i25. dmesg says I ought to find them at 5i25.0.gpio.025<->027 (p2-5-6-7). And in checking that, I just for another problem, pwmgen dir isn't getting to gpio.027, and show pins doesn't say what or why. More searching thru the hal file. And it cannot be found in the .hal file! More head scratching to do. Possibly a pwmgen type 1 is missing and searching thru the hal file it is not declared. So where do I put that declaration? or do I have a bad p2 cable? Ran LCNC, used halmeter to look up that param, and its properly set to a type 1. I think that says bad cable at p2-7? Go "ring" the cable, 'twouldn't be the first time with these damned IDC connectors. We celebrate 29 years without an Alaskan Divorce today, so I'm trying to take better care of Dee today like feeding her a little closer to normal time and such. And I get the left eye done early Tuesday. That ought to help my vision a bit. But the coming week is likely a sit and wait week anyway, connecters and cable to wire it all back up are in shipment from some place I can't pronounce on the other side of the big pond. :) Take care Andy & thanks. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
