So, you would want to read EXPOS parameter as well with autoexposure enabled, right?

From your 1st letter I got it that you would like to read/set camera parameters from a command line.

My bad again. But you'll have to print the contents of the response if you would like to actually see the parameters values. Try the following: Create test.php: > <? > $r = file_get_contents(" > http://192.168.0.9/parsedit.php?immediate&DCM_HOR&DCM_VERT&BIN_HOR&BIN_VERT&EXPOS > "); > echo $r; > ?> Then launch it from a browser: > http:/localhost/.../test.php or a command line: > $php test.php In the command line you'll see something like: > <?xml version="1.0"?> > <parameters> > <DCM_HOR>1</DCM_HOR> > <DCM_VERT>1</DCM_VERT> > <BIN_HOR>1</BIN_HOR> > <BIN_VERT>1</BIN_VERT> > <EXPOS>19883</EXPOS> > </parameters> If you specify values for the parameters they'll be applied. The response will read an old value though - so you would need to do one more read. shouldn't it be something like this?: > > wget " > http://elphel/parsedit.php?immediate&DCM_HOR=2&DCM_VERT=2&BIN_HOR=2&BIN_VERT=2<http://elphel/parsedit.php?DCM_HOR&DCM_VERT&BIN_HOR&BIN_VERT> > " > but this again only sets up skpping at half res. and pixel-binning "at > half res." (by avraging) isn't it? > Yes, that's correct. how do I get the luminous advantage of pixel binning (by summing)? > We don't have this setting in the upper level parameters. Do you have the datasheet for the sensor? I looked it up. You can switch between summing and averaging in register 0x20, bit 5. The commands from the camera terminal are: read: > fpcf -i2cr16 4820 1 write: > fpcf -i2cw16 4820 0x60 - enable summing fpcf -i2cw16 4820 0x40 - switch back to averaging Where 0x[48] is the I2C sensor's address, 0x[20] - register address. You can connect to the camera through telnet. Or go http://elphel -> Terminal and type the commands there. This way of changing the sensor parameters will not be in sync with the frames' exposure period - so you might be getting a transitional broken frame(s).
