Camera V2 NoIR Shutter Speed - Raspberry Pi Forums

-

i'm trying build astronomical sky camera need long exposure times shutter speed parameter not working expected. can't see in between 1sec , 6sec exposures. example:

raspistill -ss 6000000 -awb off -awbg 1,1 -iso 800 -t 60000 -o file.jpg

expect give me 6s exposure exposes 1sec. i've tried 5000000, 4000000, 3000000 , provide 1 sec exposure too.

raspistill -ss 6000001 -awb off -awbg 1,1 -iso 800 -t 60000 -o file.jpg

adding 1 microsecond exposure, 6 second exposures. can't in between.

strangely enough if use arducam 5mp: ov5642 camera, exposures seem work correctly. there wrong rpi noir camera?

appreciated.

perlova

i can 12 seconds on v2 camera, driving python rather command line, raspistill give long gap between photos if 1 @ time.

posted nasic python code here

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
