hi!
after developing a full INDI client for my telescope controller project TSC (which uses INDI for direct control of cameras for guiding and astrometry), i have a question. i start the INDI server on the raspberry that does the telescope control, and i use it as a remote INDI server subsequently. for this purpose it would be nice to start also drivers that are not directly needed by the controller - is there a list of all available driver names in text/html format. i honestly speaking don’t want to pick each name from the Devices-pages here :D

hi!
just to close the topic - yes, i was stuck in a total rut. i did not understand that properties can be dynamically attached ... sorry for molesting you guys ...

I don't manage to resolve it....


hi!
let me guess. you get an error stating that exposure was started 3 times and cannot be finished?

this is a problem i know from the 120 MM. there is a workaround.
- use a USB 2 cable, NOT a USB 3 cable
- try the first exposure with 0.01 s exposure time. after that, you can do longer exposures.
- you can also try to set the camera to 8 bit depth.

maybe that helps ...

hi pep!
well - ttySx is he standard UART, the old style miniDIN 9 COM1 port hardly to be found on any computer anymore (the pi still ha it via dedicated GPIO pins, but no direct connector). the ttyACMx thing - well - i don't think that this is the problem as your cp2102/9 hooks up to ttyUSB0. maybe a try with the pi3+ might shed more light on that problem ...

hi!
i checked the doc - USB 1.1 seems to be the response from this converter, which is apparently an older model.
as far as i can tell, all is fine with your converter. so it is either a hardware failure (scarce) or a software problem ...

i am running out of suggestions, maybe someone with a better understanding of udev rules might be able to help.
... i still see the focuser as a separate device here - which is suspicious.

one idea:
- move the udev rules file to a different location so that they are not executed at startup
- reboot
- now, you cannot access /dev/ttyUSB0 UNLESS you are root OR - i hope that works - you give everyone else access to the device by typing

sudo chmod a+rw /dev/ttyUSB0

in the terminal. start kstars in the same terminal. if this works (unless i typed some BS, which is always possible), then the udev rules are the problem. this is not a remedy, by the way. next time you reboot, access is gone again ...

hi!
true, but basically, this is the offset, isn't it? for the zwo cameras, it is reported correctly as 32xxx and if subtracted, this allows for rescaling of the 16 bit data from the raw BLOB as received by INDI ...

hi!
USB devices can also be set in the dev rules, i think ... but i have a more important question: why are you running on USB 1.1????

it should work, i am just wondering.

worth a try as well - but the dmesg log pep posted clearly states that the adapter connects to ttyUSB0 ...

Hi! Sure?

KEYWORD: BZERO
REFERENCE: FITS Standard
STATUS: reserved
HDU: image
VALUE: real
DEFAULT: 0.0
COMMENT: zero point in scaling equation
DEFINITION: This keyword shall be used, along with the BSCALE keyword,
when the array pixel values are not the true physical values, to
transform the primary data array values to the true values using the
equation: physical_value = BZERO + BSCALE * array_value. The value field
shall contain a floating point number representing the physical value
corresponding to an array value of zero. The default value for this
keyword is 0.0.

hi!
i think that there is nothing wrong with your CP21xx. i tried it here and
pi@TSC:~ $ udevadm info -a -n /dev/ttyUSB0 | grep serial

gives me

SUBSYSTEMS=="usb-serial"
ATTRS{serial}=="0136F636"
ATTRS{serial}=="0000:01:00.0"

for my CP2104. the first attribute is the iSerial serial number. that is not a second a device. what IS strange is that your device has serial number 0000 ...

can you send us the result of
lsusb -v -d 10c4:ea60

???

BTW, you can simply copy the content of your terminal by marking the output and using Ctrl-Shift-C instead of Ctrl-C ...

hi!

shouldn't the offset be listed with the BZERO keyword in FITS???
