GitHub175 | [scripts/master] include all demo in data partition - Xiangfu Liu | 03:14 |
cladamw | wpwrak, [un-used fpga pins]: (bank0, none) (bank1, 1) (bank2, none) (bank3, 19) after compiled. i should have compiled every time. ;-) | 04:30 |
cladamw | well... needs to set few rules to find... phew, my faults. | 04:30 |
cladamw | (J21/J22) regards to if 9*2 female header to 10*2, you can ask wolfspra1l for idea. ;-) | 04:32 |
cladamw | i'll back. | 04:35 |

xiangfu | Fallenou, http://downloads.qi-hardware.com/software/images/Milkymist_One/latest/doc/ | 04:57 |
xiangfu | Fallenou, now I build the handbook.pdf and midi.pdf form Werner. | 04:57 |
wpwrak | cladamw: http://en.qi-hardware.com/mmlogs/milkymist_2012-02-27.log.html#t14:47 | 06:19 |
wpwrak | note how long it took wolfgang to think about the issue ;-) | 06:19 |
cladamw | ha... | 06:21 |
cladamw | alright, so now let's go for what else pins we can add. :) | 06:22 |
cladamw | 10*2 means we can still have 4 extra assignements for pin. ;-) | 06:23 |
wpwrak | on J21, i'm not sure we want to add more signals. they would either be beyond GND or beyond 5V. neither location looks too tempting. | 06:24 |
wpwrak | maybe we could just shift it by one row and make pins 1 and 2 GND ? | 06:26 |
wpwrak | or, rather, by one column | 06:26 |
wpwrak | J22 could get a similar arrangement: 2*GND - 2*7 signals - 2*3V - 2*GND | 06:27 |
cladamw | you meant assignements for J21& J22 are all: | 06:29 |
wpwrak | (looking at the latest change, after ERC/DRC) ah. L22_N/P have replaced 50_N/P. very interesting change ;-) | 06:30 |
cladamw | J21: 2*GND -> 2*6 signals -> 2*3.3V -> 2*5V -> 2*GND | 06:30 |
cladamw | J22: 2*GND -> 2*7 signals -> 2*3.3V -> 2*GND | 06:31 |
wpwrak | yup | 06:31 |
cladamw | ha...yes latest changes after ERC(actually i.e. compiled) ;-) | 06:32 |
wpwrak | for J21, we could also consider 2*GND - 2*6 signals - 2*3.3V - 2*GND - 2*5V | 06:32 |
wpwrak | that would make accidental contact with 5V less likely. but it would break 5V compatibility with its ancestors | 06:33 |
wpwrak | sometimes, a little DRC goes a long way ;-) | 06:33 |
cladamw | yup...since I've not planed to do compiled then, but time is end almostly. so now will always compile it. ;-) | 06:34 |
wpwrak | does the DRC take long ? | 06:34 |
cladamw | so ou want J21 to break compatibility or NO? | 06:34 |
wpwrak | in kicad, eeschema is pretty much instantaneous. pcbnew can be slow, though. | 06:35 |
cladamw | wpwrak, very fast in maybe just less than 3 seconds. I just didn't do it. | 06:35 |
wpwrak | (break compatibility) i would offer this for discussion | 06:35 |
wpwrak | ah, good | 06:36 |
wpwrak | maybe another item for the list ... | 06:36 |
cladamw | the real problem for compiling is to 'set' expected 'rule' to find un-connected wires, etc...;-) | 06:36 |
cladamw | good, but before you send I can edit draft to a latest new about J21/J22, is it okay? | 06:37 |
wpwrak | sure :) | 06:37 |
cladamw | so i make two J21 sch pages for you. wait a moments. ;-) | 06:38 |
wpwrak | btw, does M1rc2 also have J21 ? and if yes, it it like in M1rc3 ? | 06:41 |
cladamw | M1rc2 has J21which is same as M1rc3. | 06:44 |
wpwrak | thanks | 06:46 |
wpwrak | oh, and didn't we say to get rid of two of the buttons ? | 06:46 |
cladamw | yes did discuss them in irc but not final. so i keep three still. | 06:51 |
cladamw | if now is very sure, then we can reserve two un-used for J22. ;-) | 06:51 |
wpwrak | naw, i think it's good to have a few spare pins. you never know when you need one more switch or such | 06:53 |
cladamw | you'd like to keep all 3 switches ? or few spare pins ? i'm confusing. | 06:56 |
wpwrak | ah, with "switch" i meant something like a load switch. something that needs a control signal :) | 06:58 |
cladamw | btw, i may take a little time to add new part if you'd feel asleepy. I'll provide two pdf links(both are 10*2 assignements: one is compatible, the other is uncompatiple)) | 06:59 |
cladamw | i still confusing, my poor english, so keeping three switches, or get rid of two of three, then save two for unused pins ? | 07:01 |
cladamw | i read back your words, you seems to like to keep three buttons, if i misunderstood, correct me later. tks. | 07:07 |
wpwrak | get rid of two and reserve their pins for future use | 07:23 |
wpwrak | we only need one button. there be no USD 500 screen saver ;-) | 07:24 |
cladamw | phew... misunderstood. :) | 07:25 |
cladamw | okay...so but you'd like to offer this two button(get rid of) to list for discussion ? | 07:26 |
wpwrak | i think we discussed these already | 07:26 |
wpwrak | the thing i'd like to offer for discussion is whether J21 should be 2*GND - 2*5V - 2*3V3 - ... | 07:27 |
wpwrak | or 2*5V - 2*GND - 2*3V3 - ... | 07:27 |
cladamw | don't remember that discussed one button enough in list already ? ;-) | 07:29 |
wpwrak | maybe you remember this drawing ? http://downloads.qi-hardware.com/people/werner/tmp/onebutton-fsm.pdf | 07:32 |
wpwrak | that was already a long time ago. some six weeks :) | 07:32 |
cladamw | sorry I've never seen this. maybe all s/w stuff I skipped to read always. :) | 07:34 |
wpwrak | heh :) | 07:35 |
cladamw | i apologied. | 07:35 |
wpwrak | naw, no problem :) | 07:37 |
cladamw | http://octopart.com/partsearch#search/requestData&q=M20-7831046 | 07:37 |
cladamw | http://octopart.com/partsearch#search/requestData&q=M20-7830942 | 07:38 |
cladamw | 10X2 pins are more than 9X2. ;-) | 07:38 |
cladamw | finised, let me upload... | 07:39 |
wpwrak | even digi-key have one: http://search.digikey.com/us/en/products/87606-310LF/609-3555-ND/1045508 | 07:46 |
wpwrak | and here's another one: http://search.digikey.com/us/en/products/1-534206-0/A26460-ND/298974 | 07:48 |
wpwrak | (different product category) | 07:48 |
wpwrak | and 10 more in the same category. this one seems to be the cheapest: http://search.digikey.com/us/en/products/68683-310LF/609-3576-ND/1526345 | 07:50 |
wpwrak | (didn't check all the details. maybe some of them have the wrong height or such) | 07:50 |
cladamw | okay. I'll check them later | 07:51 |
cladamw | (10X2 break) http://downloads.qi-hardware.com/people/adam/m1/tmp/m1r4/FPGA_J21_breakcompatibility.pdf | 07:51 |
wpwrak | thanks ! | 07:53 |
cladamw | (10X2 compatible) http://downloads.qi-hardware.com/hardware/milkymist_one/sch/tmp/MILKYMISTONE.pdf | 07:53 |
wpwrak | oh, you did both. damn. sent my mail too fast then :) | 07:54 |
cladamw | wow..sorry | 07:55 |
xiangfu | cladamw, great PDF. | 07:57 |
xiangfu | miss 'Drawn By: Adam' :-) | 07:57 |
cladamw | (8.5mm hight) Molex: 0901512120 | 07:57 |
cladamw | , Harwin: M20-7831046 | 07:57 |
cladamw | xiangfu, no problem, this was done by Sebastien originally. | 07:58 |
wpwrak | xiangfu: right ... well, he's the only one who can do it ;-) | 07:59 |
xiangfu | oh. | 07:59 |
xiangfu | sorry. | 07:59 |
xiangfu | Modify By: adam :-) | 07:59 |
cladamw | wpwrak, let's see yours in digikey. checking... | 08:00 |
cladamw | wpwrak, yes, (links) yours are for high in 8.5mm, 8.64mm, 7.01mm | 08:06 |
cladamw | i should sorting for filter again. ;-) | 08:07 |
Fallenou | xiangfu (handbook and midi pdf) thanks ! | 08:15 |
cladamw | wpwrak, under digi-key's catagory "Connectors, Interconnects::Board to Board - Headers, Receptacles, Female Sockets", results at height (5~8.5mm) @ (520~847) Quantity Available. The FCI brand's p/n: 87606-310LF is good. | 08:48 |
wpwrak | yes, looks good to me | 08:56 |
cladamw | nice ! | 08:58 |
cladamw | wpwrak, first search about getting rid of two buttons: http://en.qi-hardware.com/mmlogs/milkymist_2012-01-09.log.html#t20:33 | 09:00 |
cladamw | wpwrak, so this idea has been agreed already by more people ? or just you only now ? i knew the idea of one button has been discussed, but don't know if else agreed already. ;-) | 09:02 |
wpwrak | here's a more recent thread: http://en.qi-hardware.com/mmlogs/milkymist_2012-01-29.log.html#t19:36 | 09:14 |
wpwrak | the keyword here is: Jan 29 16:41:36 <lekernel> great! | 09:14 |
wpwrak | ;-) | 09:14 |
wpwrak | btw, this may be a cheaper alternative. although from non-stock land: http://search.digikey.com/us/en/products/SSW-110-22-F-D-VS-K/SSW-110-22-F-D-VS-K-ND/2345199 | 09:16 |
cladamw | aha... happy for keyword. | 09:17 |
Ladislas | hello lekernel | 09:20 |
cladamw | wpwrak, different family | 09:29 |
cladamw | wpwrak, it's okay though. some else is cheaper. http://octopart.com/partsearch#search/requestData&q=87606-310LF | 09:31 |
lekernel | y0 Ladislas | 09:40 |
Ladislas | dilemma : get rid of economy by making our own processors :-) | 09:51 |
