PineNote Development/TODOs

Kernel/driver TODOs

These exist, but they haven't been written down yet.

Artifacting

There is some artifacting with the current driver that has been difficult to diagnose and resolve. The github issue tracking this is here: https://github.com/PNDeb/pinenote-debian-image/issues/47

Some members of the community have been considering hiring an e-ink professional to consult on this issue. The thought is to hire someone with expertise in developing drivers for e-ink displays to provide advice and pointers, not to do the actual work (because that's expensive).

Userspace TODOs

The TODOs in this space are organized around what functionality they enable. A table of the important functions that a user may want in the PineNote and a status are listed below:

Functionality	Approaches (apps)	Level of support (subjective)	Supports	Does not yet support	Notes
Reading Documents	Koreader	Great	Fully featured ebook reader; Supports many filetypes;	Handwritten notes	Large user base on many devices; codebase has a somewhat of a reputation for being messy
	Xournalpp	Good	Reading/writing PDFs and other files;	No definition support (long-press for definition)	Billed more as a note-taking app than a document reading app

Themes

A lot of getting the PineNote to work nicely will be theming things appropriately. Please list themes for various components here:

GNOME

Untested: https://github.com/fujimo-t/gnome-shell-theme-e-ink

GTK

Status table draft

This table is a draft for the wiki development page:

Functionality	Component	Status (Android from factory)	Status (Linux)	Notes
Bootloader	Bootloader	Android only	WIP for Linux	Booting into linux requires a patched U-Boot. Instructions here.
Operating System	Stability	WIP		Users have successfully booted Arch, Manjaro, and Debian. Debian has most support right now.
	Suspend	Works		This kernel patch adds suspend support.
	Updates	WIP		GPU libs (mesa) and mutter rely on patched packages. These should not be updated via the package manager at the moment, make sure to exclude them.
	Networking	Works
Components	E-Paper Display	WIP		Mostly functional. There is some ghosting and work remains, but the device and screen are usable.
	Touch	Works
	Bluetooth	Works, audio stutters		Switching the driver provides stable connections for keyboards, but audio still stutters. Trying to fix this here.
	Sensors	Unsure		Light sensors? Rotational sensors?
	Buttons	Works		Power button works.
Accessory compatibility, spare parts	Spare parts	Not available yet		Spare parts currently not available yet in the store.
