Sierra digital cameras on the Apple II
3 days ago
- Investigated Sierra-class cameras from libgphoto2, supporting over 80 models, but limited to 640×480 JPEGs on Apple II.
- Purchased two cheap Sanyo cameras (VPC-G1 and VPC-G200) and implemented a modular driver for Sierra cameras.
- Driver uses a skeleton with bitfield of features and 16 API methods, most optional; only _wakeup, _set_speed, _get_information, _get_picture required.
- Implemented nearly all features except thumbnail retrieval due to memory constraints in the UI.
- Serial communication limited to 19200 bps on Apple II because of timing issues with the Sierra cameras' serial chip.
- Refactored code to compress binaries and extend the loader to handle zx02 compression, freeing up floppy space for future drivers.
