Hi FergusL
12:52
FergusL
hello se6astian
12:52
se6astian
I made some progress with the PHP code:

I won't have the time to answer on the ML before going to class today, sorry
12:52
FergusL
okay
12:52
FergusL
sorry i've been busy lately
12:52
se6astian
I ported your code to calculate exposure time to php for example
12:53
FergusL
ha yes nice
12:53
se6astian
now you can get/set exposure time from the webinterface

morning eveyone!

s3bastian
hi there
17:42
s3bastian
just sent the email to Cern!
17:54
Bertl
great!
18:04
Bertl
btw, I haven't tested the web frontend, but the math seems to be seriously off
18:05
Bertl
what is CalcExposureTime() supposed to do?
18:07
Bertl
why does CalcExposureRegisters() return values outside 16 bit?
18:07
gwelkind
left the channel
18:09
s3bastian
so far the setting and getting of exposure times showed results that matched actual values (as displayed by snap2)
18:11
Bertl
okay, so, why does CalcExposureTime() take a time?
18:11

18:12
s3bastian
limiting to 16bit values for the registers is a good idea though, let me add that to my todo list.
18:13
Bertl
i.e. how do I calculate the exposure time from 2 registers, the reg82, reg85 and bits/lvds with the library functions?
18:13
s3bastian
I ported FergusLs code from the metadatareader: https://github.com/apertus-open-source-cinema/alpha-software/blob/master/misc_scripts_and_utilities/metadata-reader/metadatareader.c#L60
18:13
Bertl
$time is the register values?
18:19
s3bastian
yes register values appended
18:19
s3bastian
exposure(swap_endian(registers[i], swap_endianess)*65536+swap_endian(registers[i-1], swap_endianess),
18:19
s3bastian
https://github.com/apertus-open-source-cinema/alpha-software/blob/master/misc_scripts_and_utilities/metadata-reader/metadatareader.c#L233
18:19
Bertl
I pushed a simple plausibility check
18:19
s3bastian
thanks

Bertl
https://github.com/apertus-open-source-cinema/alpha-software/blob/master/misc_scripts_and_utilities/webserver_root/etest.php
18:20
Bertl
run it with 'php etest.php' on the command line
18:20
Bertl
http://paste.linux-vserver.org/40185
18:21
s3bastian
added to todo list
18:21
Bertl
the first two columns are the calculated register values
18:21
Bertl
the second two columns are the calculated register values when the calculated time is used to calculate them
18:21
Bertl
(they should be identical)
18:22
Bertl
the 7th column is the time in ns, the 8th column the calculated time from the registers
18:22
Bertl
(again, they should be almost identical)
18:23
s3bastian
thanks
