In the genicam xml code for my camera (FLIR SC7600 infrared cam) there are several calculations for device registers but I do not understand the mathematical expression within the formula tags
example:
<Formula>(SEL = 1) ? 0x0000A050 : ((SEL = 2) ? 0x0000A054 : ((SEL = 3) ? 0x0000BB54 : ((SEL = 4) ? 0x0000BB58 : ((SEL = 5) ? 0x0000BB5C : ((SEL = 6) ? 0x0000BB60 : ((SEL = 7) ? 0x0000A04C : ((SEL = 8) ? 0x0000A058 : (0xFFFFFFFF))))))))</Formula>
Any ideas?
Hi Tobias,
It is just an ugly array access.
output = array[SEL] if SEL in [1..8], 0xffffffff otherwise
with:
array = {0x0000A050, 0x0000A054, 0x0000BB54, 0x0000BB58, 0x0000BB5C, 0x0000BB60, 0x0000A04C, 0x0000A058}
Emmanuel.
Thanks!
I am trying to figure out registers on our camera (FLIR/CEDIP, SC7600 ) not in the xml file.
It has a message channel, needed for additional functionality, but i am unable to get it started and need to figure out a few of the registers that according to wireshark is being written/read to.

Events are not supported yet by Aravis. It would be a nice addition.
It should be quite simple to add, we already have a thread for the heartbeat mechanism that could also handle incoming event packets.
But as usual this work can only be done by reverse engineering.

FUI:
UDP payload of these packages from my camera starts with:
0x420000c2
then some length, counter and timestamp.
1 byte per package or just an OK seems to be sent for each write to UART register.
example
420000c20014010f00009000ffff00000000000004db484901000000 means “OK or character recieved”
when it starts to transmit a sequence, several packages looking like:
420000c20018011700009000ffff00000000000004dbc73b020000000200c100
here the fourth byte from the end is important (0x02) signalling STX
several more packages follow.
example of characters/numbers response sequence (once the right command have been issues via writes to the UART register):
0x02 (STX)
0x0d (length 13)
0x00 (NUL)
0x47 ( G )
0x53 ( S )
0x4E ( N )
0x2C ( , )
0x31 ( 1 )
0x2C ( , )
0x31 ( 1 )
0x35 ( 5 )
0x38 ( 8 )
0x39 ( 9 )
0x34 ( 4 )
0x32 ( 2 )
0x2C ( , )
0xDA (checksum)
0x03 (EAX)
message reads
GSN,1,158942
meaning:
Get Camera Serial Number, command was understood and executed, serial 158942
