Hello friends, I have been using Kstars and Ekos for some time and although I have a Sbig St2000XMC connected by usb, I need to use a Sbig ST7ME but with parallel port for photometry. With windows XP and MaximDl I have no problems connecting, but on Ekos it does not recognize it and according to INDI drivers says that if possible. Can anyone help me with this problem? Thanks

Can anyone help me with this? Thanks

Hi Juanjo

I have succeeded in getting the ST-7 recognized by INDI SBIG Librally by installing the SBIG Parport Driver.

SBIG Parallel Port cameras
github.com/worlickwerx/pi-parport/wiki/S...arallel-Port-cameras

To use sbig-parport repo
github.com/worlickwerx/sbig-parport
clone the udev rule installation instructions

$ cd . /Downloads/sbig-parport-master/driver
$ make
$ sudo make install
Just in case "depmod" seems to be skipped during installation
$ sudo depmod -a

and then load the sbig-parport (and parport-gpio) module.

$ sudo insmod /usr/lib/modules/x.xx.x-xx-generic/extra/sbiglpt.ko
( sudo find / -name sbiglpt* → x.xx.x-xx )

When sbiglpt gets the parallel port, Kernel Modules on HardInfo will be told

sbiglpt

appears in Kernel Modules on HardInfo, and SBIG-enabled applications based on the SBIG SDK will detect the LPT1 camera.

Conflicts with other modules
Check HardInfo to make sure that the lp and ppdev drivers are not loaded at the same time as sbiglpt.
( $ sudo apt install hardinfo )
You may want to add the module to the blacklist in advance.
Edit blacklist.conf.

$ sudo nano /etc/modprobe.d/blacklist.conf

Add the contents of "blacklist-lp.conf" in the /modprobe directory of the repository as a reference.

# sbiglpt cannod load if lp device driver claims the only parallel port
blacklist lp
blacklist ppdev

Thank you! I add this information to the driver documentation.

If you cannot connect ST-7 with INDI SBIG Librally
Previously, the drivers that could access SBIG Parport were
libsbigudrv2, libsbigudrv2-dev
once installed.

$ sudo apt update
$ sudo apt install libsbigudrv2
$ sudo apt install libsbigudrv2-dev

Installing these will exclusively erase the indi-full installation, so reinstall it again

$ sudo apt install indi-full

Doing this... for some reason, the ST-7 connection works fine.
When I re-install indi-full, this time libsbigudrv2 and libsbigudrv2-dev are exclusively erased, but there is some file left, which I think is the key to connect SBIG Parport and INDI-SBIG.

Hi Fumiaki

Thank you very much for the extensive and accurate information. I will follow the instructions you send me and I will tell you if it works.
There are other friends in Spain who have Sbig with parallel port and will be happy for this to work. Thank you very much for your interest
