| 03:50 | Bertl | off to bed now ... have a good one!

| 05:32 | irieger | Bertl_zZ: Ok. Just thought/hoped there is something implemented ;-)
|
| 05:45 | John_K | hey
|
| 05:45 | John_K | Bertl_zZ: se6astian|away: either of you about?
|
| 05:45 | John_K | one *last* component question: what values are used for L1-L18 on the power board?

|
| 07:56 | Bertl | morning folks!
|
| 07:56 | Bertl | irieger: start coding :)
|
| 07:57 | Bertl | John_K: sec, we should have an almost complete BOM by now
|

|
| 08:43 | irieger | Today is the last day in my nice lab for this year, our school is closed till beginning of january than. So today I'll shoot some tests with tungsten and HMI light to have some good lit images to play with the next days. the basement-lab at home is only with a construction light ...
|
| 08:44 | irieger | (Which is a good and cheap light source with a continous spectra which is why I bought a larger second one a few weeks ago so it's not completly bad)
|
| 08:46 | irieger | Bertl: btw. i can get 37 frames in full resolution without killing the linux ;-)
|
| 08:51 | Bertl | interesting
|
| 08:53 | Bertl | ah, yes
|
| 08:53 | Bertl | (1024-128)*1024*1024/(4096*3072*12/8*64/48) = 37.333
|
| 08:57 | irieger | yep, did the same calc ;-)
|
| 08:58 | irieger | mostly. Why that 64/48 at the end?
|
| 08:58 | Bertl | because we store four sensel (4x12=48) in a 64bit word
|
| 08:59 | irieger | Ok. Did the calc without it and thought I'd get a bit more in there ;-)
|
| 08:59 | Bertl | the other 16bit are used for the overlay on HDMI out (which could be avoided for just snap sequences)
|
| 09:02 | irieger | btw. I just did my first non-3072 image to test something and sam that register 2 is 456 as expected but reg 34 is 2616 while reg 1 is 2160 as expected. Would have expected 32 to also be 2160.
|
| 09:04 | Bertl | slow down, what number of lines and how did you set them?
|
| 09:04 | irieger | ok, got it. Good to know but no problem for me as 37 frames is god for now
|
| 09:04 | irieger | cmv_snap3 -L2160
|
| 09:05 | Bertl | that will center the read-out area in the middle of the sensor
|
| 09:05 | Bertl | i.e. (3072-2160)/2 from the top
|
| 09:05 | Bertl | and similarily (3072-2160)/2 from the bottom
|
| 09:06 | irieger | that's what I hoped which is good (as I wrote "as expected"). And at the end I meant 34. As it is the size not the last line due to the data sheet
|
| 09:07 | Bertl | ah, so you are reporting a bug in cmv_snap3 then? :)
|
| 09:07 | irieger | "The value in this register defines the number of lines of the first windows (min=1, max=3072)
|
| 09:07 | Bertl | just change the code, recompile it and see if that works for you
|
| 09:07 | irieger | jep, I'd say so. Wanted to check back if it may be one ...
|
| 09:07 | Bertl | then make a diff and upload it somewhere :)
|
| 09:07 | irieger | ok
|
| 09:08 | irieger | I already wondered why /opt/BERTL isn't in a git ... ;-)
|
| 09:08 | Bertl | it will soon be in beta-software
|
| 09:08 | Bertl | probably as userspace-tools
|
| 09:08 | Bertl | I just have to merge the different branches we have right now
|
| 09:09 | Bertl | i.e. your cmv_snap3 is slightly different from the one used in other Betas because of the sequence feature
|
| 09:10 | irieger | ok.
|
| 09:12 | irieger | seems to work. The captured data was already 2160 but I just wondered why the register carried another value ...
|
| 09:12 | Bertl | as you can see, the sequence code was a rather quick hack with little to none testing :)
|
| 09:13 | irieger | Bertl: Don't tell it anyone. "We have unit tests that check everything, even themselves ..." ;-)
|
| 09:16 | Bertl | feel free to let them check my code :)
|
| 09:17 | irieger | you think I have tests for anything of my hacky matlab helper code I currently use for "live" analysing the data? ;-)
|
| 09:17 | Bertl | of course :)
|
| 09:17 | irieger | If you only use code by yourself you don't even need good error messages I'd say ;-)

| 17:26 | John_K | Bertl_oO: it seems a ferrite bead has been spec'd instead of an inductor for L
|
| 17:26 | John_K | components
|
| 17:26 | John_K | any specific reasoning behind that?
|
| 17:36 | Bertl_oO | yes, it was always designed as a filter, the inductor was more a 'missing symbol' back then
|
| 17:36 | Bertl_oO | we will probably update the schematic in the near future

|
| 18:01 | John_K | ok I *think* I have a complete BOM now
|
| 18:01 | John_K | crosses fingers
| | 18:01 | Bertl | excellent!
|
| 18:02 | John_K | I was relying on the google docs spreadsheets at least having a complete component listing which wasn't true for the power boards
|
| 18:02 | John_K | I hope I didn't miss anything, but I guess the board house will let me know :P
|
| 18:03 | Bertl | the BOM I linked is the one we used for the most recent boards, and they are working fine
