Free 2 keyboard software for linux

Optimus OLED Keyboard Linux Driver project is intended to provide a generic linux driver for OLED-based hardware made by Art. Lebedev Studio.
The current goal is to support the Optimus Mini Three keyboard.
Main features:
- Uses libusb to communicate with device (no specific kernel driver needed)
- As the kernel-provided module for pl2303 didnt work in our case, we recoded the driver with libusb
- Uses libpng to read PNG images, and display them
- Detects when a button is pressed
- Implements OLED_PROTOCOL_SET_IMAGE, OLED_PROTOCOL_POWER_ON, OLED_PROTOCOL_POWER_OFF, OLED_PROTOCOL_SHOW_OLED, OLED_PROTOCOL_GET_IDCODE, OLED_PROTOCOL_SET_IDCODE, OLED_PROTOCOL_SET_BRIGHTNESS.
- Support for more than one OLED Mini Three connected to the same computer
- All USB code is in a static library
Enhancements:
- One of the most annoying bugs (auto-switch-off of the key display after five seconds) has been fixed.
- Functions similar to the ones provided by the original Win32 library for image color settings are also available, allowing you to set color temperature and gamma.
- Theres better support for input, using threads as libusb only provides a blocking way to read data (or some bytes are missed).

Midirecord is a simple command-line application to record a MIDI file with your MIDI keyboard.

Midirecord project also features automatic recording to a MIDI file when you play electric piano, and thus it may be used as a "recording daemon".

KeyTouch is a program which allows you to easily configure the extra function keys of your keyboard. This means that you can define, for every individual function key, what to do if it is pressed.

When you buy a new keyboard a CD-ROM will probably included. This CD-ROM contains software to configure the extra function keys (the image above shows an example of extra function keys) of your keyboard with. The problem however is that most of the times the software is not available for Linux.

KeyTouch is the solution to this problem. It allows you to easily configure the extra funtion keys of your keyboard.

KBDE is a keyboard emulator. It allow emulate keyboard input for keyboardless x86 computers.
KBDE include following:
- linux kernel module
- user-space tools
- development library
Enhancements:
- Support was added for Linux kernel versions 2.6.20 and later.

keyfuzz project is a Linux input layer scancode table manipulation tool.

You may use keyfuzz to manipulate the scancode/keycode translation tables of keyboard drivers supporting the Linux input layer API (as included in Linux 2.6).

This is useful for fixing the translation tables of multimedia keyboards or laptop keyboards with special keys. keyfuzz is not a daemon like Gnome acme which reacts on special hotkeys but a tool to make non-standard keyboards compatible with such daemons.

keyfuzz should be run once at boot time, the modifications it makes stay active after the tool quits until reboot. keyfuzz does not interact directly with XFree86. However, newer releases of the latter (4.1 and above) rely on the Linux input API, so they take advantage of the fixed translation tables.

The distribution includes scancode tables for Medion 9580F and MSI S270 laptops. Feel free to send me scancodes table, I will integrate them into my package!

TkViewMan is a graphical man page viewer for Linux. TkViewMan project is written in Tcl/Tk, using the BLT extension. TkViewMan is free software and is distributed under the GNU General Public License.
Main features:
- Tabs for multiple man pages
- Ability to find all man pages for a command, with each man page getting its own tab
- Ability to open as many tabs as desired within the main window, which can be scrolled if needed
- Ability to search a man page
- Keyboard shortcuts for creating/removing tabs
- Command history using arrow keys
