LCD is a Perl Module that allows a developer to write to Serial LCD displays. It allows for modules to be loaded for supported displays (Such as LCD::MatrixOrbital) LCD::MatrixOrbital is a Perl module that allows a developer to write to a Matrix Orbital LCD Serial Display. All functions of the LCD displays are are accessible including the keypad, with coming support for extra VFD commands.
LCD-Linux is a Linux software abstraction layer to drive LCD alphanumeric displays. It features complete VT102 console emulation and aims to be as general and flexible as possible. It consists of two kernel modules, lcd-linux and the display driver. Currently, only the Hitachi HD44780 is supported, but drivers for other LCD controllers can be easily written.
LCDproc is a utility to drive one or more LCD (and LCD-like) devices attached to a host. It is comprised of a server, which uses a modular device driver system to control attached displays, and one or more clients to gather data as appropriate and send screen data to the server. The included client displays a multitude of system statistics (CPU/memory/disk usage, uptime, date and time, temperature, etc.). Multiple clients can connect to the server simultaneously, and clients can set priorities on the screens they provide to influence in what order items are displayed. This facility can also be used to "pop" critical screens (such as an entry from syslog from a log-watching client). All functionality is implemented in userland. Support for many display devices and several platforms (Linux, *BSD, and Solaris at least) is included.
