Can pilomar run on RPi4B with Bookworm o/s? #58

Closed Short-bus closed 5 months ago

Short-bus commented 5 months ago

Pilomar currently (Jan.2024) runs on Buster O/S 32bit. The Bullseye release caused too many dependencies to break, so is not used. Tests show that pi-lomar can be run on RPi5 with Bookworm 64bit. Can the same be done on an RPi4? I think that libcamera will be an issue, but hopefully it's relatively straightforward to upgrade to that because the libcamera-jpeg command seems to be backwards compatible with the older raspistill command.

Converted the hardcoded raspistill commands into templates. These are held in the parameter file. When the file is initialised the templates are populated with either raspistill or libcamera-still command templates. The decision is made currently based upon the operating system. The astrocamera() class uses the templates and populates runtime values as needed. On Bookworm O/S the separate pidng extract of the raw bayer data is nolonger needed, it's available now as a command line option on libcamera-still.

This is probably the main barrier to running pi-lomar on Bookworm 64bit on the RPi4B, initial tests suggest this gets everything working OK.

This does NOT clear the software to run on a RPi5 yet because that has additional GPIO changes to handle.

The initial build script is much simpler too.

Initial support for Bookworm 64bit on RPi4B has been running now for a couple of weeks on a test build. Have added features into the 2024-01-Issues branch ready for merging back to the main branch.

Done.
