reMarkable Stuff

Collection of reMarkable related apps, utilities and libraries.

Projects

Yaft

A fast framebuffer terminal emulator.

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

Rocket

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 flaky gestures.

Tilem

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.

rMlib

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

rm2fb

Custom implementation for reMarkable 2 framebuffer, latest version only tested on xochitl 3.5. Relies on lower level hooking in order to support newer xochitl versions. Also does not depend on the QT framework.

SWTCON

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

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

$ mkdir build && cd build

# For toltec:
$ cmake -DCMAKE_TOOLCHAIN_FILE="/usr/share/cmake/$CHOST.cmake" ..
# For remarkable:
$ source /opt/codex/rm11x/3.1.2/environment-setup-cortexa7hf-neon-remarkable-linux-gnueabi
$ cmake ..

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

# To create an ipk file:
$ cpack .

Emulating

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 -DEMULATE=ON ..
$ cmake --build . --target yaft
$ ./apps/yaft/yaft # Should launch Yaft with an emulated screen in a separete window.
