This repo is for archive and knowledge sharing purposes. There is no support because I don't use these cameras anymore- but pull requests and forks are welcome. It's for developers who want to explore GIGE camera control with a 100% pure GO solution (no drivers needed). I developed this for aca2440 cameras, but has also been tested with some Lucid cameras and should work with small changes for other GIGE camera manufacturers as well.
About
Controlling GIGE Vision cameras like the Basler line of ethernet cameras (i.e. aca2440-20gc). This is a pure Go application that enables reading and writing to memory registers in the camera over a UDP connection.
Quick start
Dependencies - no drivers are needed just GO!
It has been tested on Linux and MacOS platforms.
Change directory to cmd/gige, go build, connect your camera and run it -
GIGE Camera is required and make sure you can ping it on the network.
You should see the program named 'gige' compiled in there:
Now find your device (-d) by running ifconfig and look for the ethernet device connected to you camera POE switch
The remote address (-raddr) is the ip address of the camera you want to control. If you don't know the IP addres, then you can use the broadcast address 255.255.255.255.
The top section returned, is what we sent, the bottom (packets received) is what we got back from the camera.
$ ./gige -d en9 -raddr 255.255.255.255
$ ./gige -d en9 -raddr 255.255.255.255 -readAll
Troubleshooting
If you get the message "Unable to find interface", then either your camera is not connected through the POE switch to your computer, or you provided the wrong interface (-d).
To find the ethernet interface you just plugged your camera switch into
Run this right after you plug in the cable to your linux or macos computer to see it show up. You are looking for the port number (in this case 9).

Then you can verify with ifconfig. You should now see a new entry.
