I have tried to connect ST7E parallel port with SBIG driver, but I have got the following error message: Device not found.
I have tied sbiglpt0, sbiglpt1...
The libsbigudrv0 and libsbigudrv2 packages are installed.
I use LUbuntu
I have /dev/parport0, and I created a link /dev/lpt0, but it was not working.
How can I connect to ST7E via parallell port?
Thank you Jim for the parport driver though, this raised a question / wish list item for the older SBIG cameras. SBIG made a serial adapter for these cameras which has long been discontinued, however, today USB to Parallel adapters are available and affordable.
So, this daunts the wish for a modification of the driver to allow it to take advantage of such an adapter. I suspect this is possible and even SBIG might provide the serial code for such. Just an idea.
I was thinking the same thing, and I did change the driver so that it does its I/O through the "parport" driver stack rather than directly accessing the x86 legacy register addresses. However, I was disappointed to discover most USB parallel port adapters don't plug into the parport stack. Instead they look like a USB printer to the OS.
I went another way and designed a parallel port "HAT" for the raspberry pi. I have a prototype that works with PHD + indi + sbigudrv reliably as long as the cable is really short. I'm working on a second revision of the hardware that hopefully will have better electrical characteristics.
This project is over here (with driver and board layout):
Thank you Jim, I will take a look at it sometime soon, I hope. I use a ST7, actually modified into an ST8, as a sky camera. And while, it was always rather slow, it was very reliable and does a nice job.
Not knowing your application of the ST7, let me just say, it is possible to install a KAF1600 ccd into that camera. It requires a slight modification of a 'cover' which holds the off axis prism for the guider ccd. Truthfully, I forget just what software I changed, but, I remember it was not too difficult. Openskyimager is able to loop it with a delay between images.
The 2 ccds are essentially the same pins out. I have attached the data sheets which I have. As for software, I searched my archives, but, you might find it easier by contacting SBIG. They used to offer a ccd upgrade in the past, so, they might share this now since the cameras are so very old.
Hopefully, the file I will attach will contain what you need. If I can help more, let me know.
Oh, I wanted to ask, which cable you have which is really short? I see 2 methods: 1 USB to parallel adapter attached at the computer with a long parallel cable. Or, 1 USB to parallel adapter attached to the camera with a long USB cable. In the first case, noise and signals of a parallel cable come into play. In the second, its vital the 5V be transmitted to the remote adapter circuit.
