Control daemon is a central place to control cameras parameters and functionality inside the AXIOM Beta Linux Operating System. Current implementation is done as systemd daemon, written in C++. Communication is done via Unix Domain sockets and flatbuffers is used to minify packages. Current endpoints to communicate with daemon are: command line interface (CLI), which allows to send commands from shell and Web Remote, a HTML UI which can be used from smartphones or tablets.
This task targets the extension of control daemon, following sub-tasks are considered:
- Move functionality from shell scripts in the firmware to daemon, so it can be called from unified place
- Add further camera/image sensor parameters, besides currently implemented image sensor plain register configuration, digital and analog gain, like white balance, color matrix for output etc.
- Implement handshake package, which would tell the Web Remote currently available modules/parameters
- Implement additional unit tests for verification of functionality, e.g. CI builds
- Linux experience
- C++ for control daemon
**Difficulty:** Low - Medium
**Mentors:** Andrej, Sebastian
- Daemon can be tested on the camera remotely, through SSH and live HDMI feed. (https://wiki.apertus.org/index.php/AXIOM_Beta_Remote_Access)
