Collection of reMarkable related apps, utilities and libraries.

Custom implementation for reMarkable 2 framebuffer. The differences are:

• Lower level hooking, removing the Qt dependence.
• Uses UNIX sockets instead of message queues. Makes it easier to implement synchronized updates.
• Supports less but newer xochitl versions

A fast framebuffer terminal emulator.

To use simply execute yaft or yaft <command..>. More usage information can be found in the yaft Readme.

Launcher that uses the power button to show.

When pressing the power button, the app drawer will be shown with a timeout of 10 seconds. After 10 seconds the device will go to sleep, unless an app is picked before that timeout. You can also interrupt the timeout by pressing the [x] button.

This allows you to switch apps without relying on gestures.

A TI-84 calculator emulator for the remarkable.

To use simply execute tilem, a prompt for downloading a ROM file will be shown. If you already have a ROM file, you can pass it as an argument on the command line.

Library for writing remarkable apps. Includes an extensive declarative UI framework based on Flutter.

This lib contains a reverse engineered software TCON. It currently still relies on some functions from xochitl, namely the generator thread routine. To use these functions it must be launched as an LD_PRELOAD library attached to xochitl. The swtcon-preload tool is an example of how it can be currently used.

Building for the remarkable can either use the toltec toolchain or the reMarkable one:

# For toltec:
$ cmake --preset dev-toltec
# For remarkable:
$ cmake --preset dev

# To build everything:
$ cmake --build build/dev
# Or to build a specific app:
$ cmake --build build/dev --target yaft

# To create an ipk file:
$ cmake --build build/dev --target package

For faster development an EMULATE mode is supported by rMlib. This allows running most apps on a desktop using SDL to emulate the remarkable screen. To enable it pass -DEMULATE=ON to the cmake configure command, without using the reMarkable toolchain of course.

$ cmake --preset dev-host
$ cmake --build build/host --target yaft
$ ./build/host/apps/yaft/yaft # Should launch Yaft with an emulated screen in a separete window.
