Free touchscreen driver software for linux

Semtech Touchscreen Driver is a driver on X for the Semtech Touchscreen as found on the GoBook III manufactured by Itronix.

It comes with a calibration program and has been tested on Linux 2.6.9.

You will need a kernel with the following options compiled.

CONFIG_SERIO_RAW=y
CONFIG_INPUT_MOUSE=y
CONFIG_MOUSE_PS2=y

Next you will need to enable raw PS/2 reporting for the touchscreen. Type in the following command:

echo -n "serio_raw" > /sys/bus/serio/devices/serio1/driver

You should see the following message:

serio_raw: raw access enabled on isa0060/serio2 (serio_raw0, minor 1)

Compiling:

Type the following command to compile the driver:

make

Installing:

Do the following as root to install the driver:

make install

Configuration:

You will need to issue this command every time the computer starts so I suggest you stick somewhere in the initalization scripts.

Add a section in xorg.conf or XF86Config that looks like this:

Section "InputDevice"
Driver "semtech"
Identifier "Semtech Touchscreen"
Option "Device" "/dev/serio_raw0"
Option "DebugLevel" "0"
Option "CalibrateA" "-369046"
Option "CalibrateB" "1114"
Option "CalibrateC" "4893014"
Option "CalibrateD" "-2152"
Option "CalibrateE" "-282719"
Option "CalibrateF" "5331971"
Option "CalibrateDiv" "-359811"
EndSection

Note that the device can also be called /dev/psaux depending on your setup.

Start X and run the touchcal program to calibrate your screen. It will ouput the calibration information

There is also a program called touchcal.pl, it requires the Perl Tk toolkit. The program will write calibration information on your X configuration file.

uLan Driver provides 9-bit message oriented communication protocol, which is transferred over RS-485 link.
Characters are transferred same way as for RS-232 asynchronous transfer except parity bit, which is used to distinguish between data characters and protocol control information. A physical layer consists of one twisted pair of leads and RS-485 transceivers.
Use of 9-bit character simplifies transfer of binary data and for intelligent controllers can lower the CPU load, because of the CPU need not to care about data characters send to other node. Producers of most microcontrollers for embedded applications know that and have implemented 9-bit extension in UARTs of most of todays MCUs. There is the list below to mention some of them:
- all Intel 8051 and 8096 based MCUs with UART
- members of Motorola 683xx family ( 68332, 68376, ... )
- Hitachi H8 microcontrollers
The driver is implemented as relatively independent layers and subsystems. Messages are prepared and received in the driver dedicated memory. This memory is divided into blocks with uniform size with atomic allocation routines.
When message is being stored into blocks, head of message with couple of data bytes is stored in the first allocated memory block. If all data cannot be stored in the first block, next blocks are allocated and linked together.
The message heads are linked in bidirectional linked lists of messages prepared for sending, processed messages and messages prepared for client notification. These lists or queues are main mechanism for transferring of messages between subsystems.
Link protocol is programmed as finite state automata with state stack, which state routines are executed by interrupt handler. State routine can return positive integer information, negative error notification or zero, which leads to wait for next interrupt. Information or error is used as input parameter when state routine is called.
When the state routine wants initiate transfer to another state routine it changes pointer to the actual state routine. If previous state routine returns nonzero value new routine is called immediately, in other case next interrupt invokes new state routine.
There is stack of callers of actual state routines which enables to constructs automata subsystems, which can be used in more places in main automata loop. Main purpose of this automata is to send or process messages coming in list of messages prepared for sending and if specified, move these messages onto list of messages prepared for client notification.
Received messages are put onto this list too. Subsystem is supervised by timeout handler, which can revitalize communication in case of die of other node. The interrupt and timeout handlers are fully SMP reentrant.
The automata subsystem uses pointers to chip driver routines for hardware port manipulation. This is only part dependent on used chip, today 82510, 16450 and OX16C950PCI. These routines can send and receive 9 bit character, connect to RS-485 line by the arbitration sequence, wait for specified time for character and initialize and close port.
File operation subsystem makes interface between OS kernel VFS and client message queues. It enables to prepare single or multi-frame messages and stores notifications of received or processed messages in clients private state structures. This part is heavily operating system dependent.
Enhancements:
- This release enables you to build the driver within the WDF framework for Windows.
- Updates to support the latest Linux 2.6.x kernels are included (tested to 2.6.19).
- Changes to allow stand-alone system-less build for ARM targets (LPC21xx) are included.
- The OMK has been selected as the default build.
- The "switch2std" script allows you to switch to the old build system.

Xbox360 Controller Driver package contains the diabolixs compiled Xbox360 controller driver for Linux on the PS3.

Its been tested with Fedora Core 5 (PPC distribution) using Snes9x and Doom.

The Xbox 360 is the successor to Microsofts Xbox video game console, developed in cooperation with IBM, ATI, Samsung and SiS. Information on the console first came through viral marketing campaigns and it was officially unveiled on MTV on May 12, 2005, with detailed launch and game information divulged later that month at the Electronic Entertainment Expo.

The Xbox 360 is the first console to have a near-simultaneous launch across the three major regions, and the first to provide wireless controller support at launch. The console sold out completely at release and by the end of 2006 had sold 10.4 million worldwide.

The Xbox 360 was the first home console to be released in the seventh generation of game consoles and competes against Sonys PlayStation 3 and Nintendos Wii. Its Xbox Live service allows players to compete online as well as download games and additional content.

HDBC PostgreSQL Driver is the Haskell PostgreSQL backend driver for HDBC.

Please see HDBC itself for documentation on use. If you dont already have it, you can browse this documentation at http://darcs.complete.org/hdbc/doc/index.html.

This package provides one function in module Database.HDBC.PostgreSQL:

{- | Connect to a PostgreSQL server.

See for the meaning of the connection string. -}

connectPostgreSQL :: String -> IO Connection

An example would be:
