(in a way, that's good - means that i can debug it with the latest boards, which support the constant frequency test mode)

oh, adam is cooking something :-)
06:24
<
wolfspraul >
cooking what?
08:37
<
wpwrak >
hmm .. the clock looks rather awful. with lots of noise just in the FM range.
08:59
<
wolfspraul >
that's the ben clock you are reusing?
09:20
<
kristianpaul >
Looks healthy
09:20
<
wolfspraul >
ah I see
09:24
<
wpwrak >
wolfspraul: yes. but it seems that i'm catching the FM outside the ben.
09:26
<
wpwrak >
's make the caps a little larger ...
09:34
<
wpwrak >
that got rid of some of the reflections, but not the "hill"
10:10
<
wpwrak >
the DC offset is rather puzzling, too
12:02
<
wolfspra1l >
roh: there it is, nice :-)
12:02
<
wolfspra1l >
thanks!
19:26

kristianpaul >
:/, i dont know why my computer just shutdown... it was installing some rtems depences last time i had contact it by ssh
19:28
<
kristianpaul >
anyway.. lets see how it goes after this
19:31
<
wpwrak >
roh: hmm, in the usb button box, where the angled sides meet the top. were the angled terminations of the side part also laser-cut ?
19:51
<
wolfspraul >
kristianpaul: do you know much about the milkymist one expansion header?
19:52
<
wolfspraul >
I am looking at it right now, wondering how flexible it is...
19:53
<
kristianpaul >
let me see
19:53
<
wpwrak >
wolfspraul: "versatile" or "how far can it bend before it breaks" ? ;-)
19:55
<
kristianpaul >
J21 is that expacion header?
19:55
<
kristianpaul >
sheet 3
19:56
<
kristianpaul >
a PCB layout i missing btw, i thin is not much hard export from altium..
19:56
<
kristianpaul >
in pdf i meant*
19:58
<
kristianpaul >
wolfspraul: whos needs IO we have
_wonderfull_ usb  :-D
19:58
<
wolfspraul >
I think there are two. J3 and J21.
19:58
<
kristianpaul >
where is J3?
19:59
<
wolfspraul >
J21 has 16 pins, J3 has 18 pins.
19:59
<
wolfspraul >
J3 is right next to it.
19:59
<
wolfspraul >
I think they are both expansion headers, no?
20:02
<
wolfspraul >
but J21 has 2*8, and J3 has 2*9
20:02
<
wolfspraul >
I think...
20:04
<
kristianpaul >
i need a rc3 pic, wait  amin
20:04
<
kristianpaul >
rc2*
20:06
<
kristianpaul >
both are 2*9
20:07
<
kristianpaul >
may be some pins not routed
20:07
<
wolfspraul >
oh you are right!
20:07
<
wolfspraul >
it was changed on rc2
20:07
<
wolfspraul >
ok so on rc2, we have 2 2*9 expansion headers
20:08
<
kristianpaul >
to be fair from where you get your rc3 pdf sch?
20:08
<
wolfspraul >
there is no rc3 yet
20:09
<
wolfspraul >
the files are a bit messy, sorry :-)
20:09
<
wolfspraul >
I just google
20:09
<
kristianpaul >
s/rc3/rc2
20:09
<
wolfspraul >
the only way to really this this up is all into kicad etc. but that's not my #1 priority right now
20:09
<
wolfspraul >
to really clean this up
20:10
<
wolfspraul >
J21 is documented on page 3, still haven't found J3
20:10
<
wolfspraul >
(and the pdf is not searchable :-))
20:10
<
kristianpaul >
ha i catch you !
20:10
<
kristianpaul >
i tought u already founded
20:11
<
kristianpaul >
i still looking for J3 too
20:11
<
kristianpaul >
(and the pdf is not searchable) PAIN !!
20:13
<
kristianpaul >
ok from m1 ucf i can see 12 IO
20:13
<
wolfspraul >
ah j3 is for audio only
20:14
<
wolfspraul >
page 1, I think j3 is hooked up to the audio codec
20:14
<
kristianpaul >
for how long it will? :-)
20:14
<
wolfspraul >
so only j21 is the fpga expansion header
20:16
<
kristianpaul >
audio, hum, what i fell is missing a extension cable here..
20:16
<
kristianpaul >
any way
20:16
<
kristianpaul >
s/fell/feel
20:25
<
kristianpaul >
for gps-sdr 13 pins are not so bad, not sure for a captiva cmos...
20:28
<
wolfspraul >
kristianpaul: yeah for image sensor it's not enough
20:31
<
kristianpaul >
The MIC2550A
20:31
<
kristianpaul >
is 2.0 USB compliant
20:37
<
kristianpaul >
but nah, is too much to deal with i think
20:39
<
wolfspraul >
kristianpaul: correct
20:39
<
wolfspraul >
Milkymist One will be fun
20:39
<
wolfspraul >
there are like 1000 really nice, really important open TODOs
20:39
<
wolfspraul >
the main thing in this project is to pick your battles wisely
20:40
<
wolfspraul >
I am still mentally wandering around the project trying to understand all the various things that work or don't work, could work, should work, will never work, etc.
20:40
<
wolfspraul >
and whether they are hard or easy to fix, depend on each other or not, and so on
22:35
<
roh >
wpwrak: nope. the angled stuff was filed after lasering it in a way that the were 'just long enough'
22:35
<
roh >
filed manually
22:35
<
roh >
also sandpaper was used
