00:05 Tom_itx it must be loading the file because it remaps the functions to different pins
00:05 tsmeow-afk knows not which file of which you s
00:07 katsmeow-afk good think i have no Iphone (etc), i'd have nitemares about the chips in it loading my little files and trying to jailbreak itself
00:08 Tom_itx the dmesg.txt file
00:08 Tom_itx i wrote another one with the original bit file
00:08 Tom_itx see where the encoders are listed in the IO Pin list?
00:09 katsmeow-afk no
00:10 Tom_itx [ 8393.963743] hm2/hm2_7i43.0: IO Pin 005 (P4-11): Encoder #1, pin A (Input)
00:10 katsmeow-afk http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/bitfiles/dmesg.txt ?
00:10 Tom_itx yes
00:10 Tom_itx i'm gettin ready to post the original
00:10 Tom_itx you can compare how they moved
00:10 katsmeow-afk holycrapwhatlanguageisthat?
00:11 Tom_itx that's a dmesg dump from linux
00:11 rue_shop2 AAAAAA FINE! I'll parallel two 1R's!
00:11 katsmeow-afk parallel them?
00:11 katsmeow-afk Tom, i don't do nix
00:12 katsmeow-afk my paws are sore, i think i'll stop for the evening, it's been a tiring physical day since 9am
00:13 Tom_itx the original file is there now
00:13 Tom_itx you can see how they get moved
00:14 Tom_itx originally encoder 0A is on IO Pin 4 but gets remapped to IO Pin 10
00:14 Tom_itx etc
00:14 rue_shop2 katsmeow-afk> non, tie the 78Lo5 to two 1k R, tie other ends of the R , one to the 78L05 output, the other to gnd, the output will read 10v
00:15 rue_shop2 because there will be 5V between gnd and vout, which will establigh a 5mA current
00:15 katsmeow-afk actually, i don't see the diff, but maybe the 2nd version is a cached 1st version
00:15 Tom_itx did you refresh?
00:15 rue_shop2 the other 1k will have the same 5mA so it'll be 5V off
00:15 Tom_itx dmesg.txt and dmesg_original.txt
00:15 rue_shop2 thanks
00:16 katsmeow-afk rue, see http://html.alldatasheet.com/html-pdf/9047/NSC/78L05/316/8/78L05.html
00:16 tsmeow-afk has no clue about dmesgs, but knows a lot about 78L
00:17 katsmeow-afk rue, see how R1 and R2 are connected? make both be 1K , and it wil output 10v
00:18 rue_shop2 I can know how it works, my mind cant function, you helped me work it out by giving me the solution and letting my work back to the problem
00:18 katsmeow-afk umm, ok
00:19 katsmeow-afk good thing you asked when you did, it's now post-midnite and my brains are off
00:19 Tom_itx ok it makes more sense now
00:19 Tom_itx it _is_ following what i told it in the bit file
00:20 Tom_itx you can see that in the .vhd file
00:20 Tom_itx near the bottom where the functions are mapped
00:21 rue_shop2 the biggest problem is what colour leds to use for power
00:21 Tom_itx blue
00:21 rue_shop2 +12 should be yellow
00:21 rue_shop2 +5V should be red
00:21 Tom_itx was used on the 24v on this
00:21 rue_shop2 and ground should be black
00:21 Tom_itx red for the 5v transceiver
00:22 Tom_itx yellow for the field power
00:25 katsmeow-afk a blackled?
00:26 katsmeow-afk i'd make the gnd led white, because if the gnd ever is active, it's a big problem
11:15 Tom_itx yay! it's working
11:16 Tom_itx 48 outputs on the one card now
11:16 Tom_itx 5-32v out
11:17 Tom_itx now to remap the io so i can leave my pendant hooked up with no conflicts
11:17 rue_house http://hackaday.com/2013/11/29/sterling-engine-kludged-together-from-whatever/
11:17 Tom_itx yours?
11:17 Tom_itx didn't click yet
11:18 Tom_itx naw, the gears are too clean to be yours
12:16 katsmeow-afk wait, you are rebuilding your *previously working* cnc?
15:24 katsmeow-afk "Hoo was released on his own recognizance......
20:58 rue_shop2 who?
22:11 katsmeow-afk yeas
22:21 katsmeow-afk there, jig made, i can and have made identical http://designerthinking.com/images/Tek-design/DSCF6491m.jpg
22:23 katsmeow-afk i used a slab of 1/4 steel to make a form for the perf'd stainless with it's 1/4 holes, holding the stainless steel still with 1/4 round roll pins
22:32 katsmeow-afk not all the perfs in the ss are in the same place :-|
22:46 katsmeow-afk other than grippy vise jaw marks, and other stuff related to "gee, first time i made any like this", i got 4 identical perf'd face plates ready for led displays
22:50 katsmeow-afk other front and side panel perforations, altho why that tall naked woman is in the image collection, i dunno : https://www.google.com/search?q=perforated+computer+front+panel&client=firefox-a&hs=fI0&rls=org.mozilla:en-US:official&source=lnms&tbm=isch&sa=X&ei=zLuaUpz2GMehkQe98YHgCA&ved=0CAkQ_AUoAQ&biw=1102&bih=385&dpr=0.9
22:59 katsmeow-afk ooo, perty : http://www.ccsiservers.com/catalog/Storage-Server-5U-Rack-RM51924B-3.jpg
