PIXet

Introduction

The PIXet Pro is a multi-platform software developed in ADVACAM company. It is a software package for Medipix family chips for acquisition control. It supports most of the available Medipix based devices (Medipix 2, Medipix3, Timepix, Medipix Quad, Timepix Quad, Widepix, Timepix3) and commonly used readout interfaces MiniPIX, FitPIX, ModuPIX, WidePIX, RasPIX, etc. Pixet provides many tools for optimization of detector parameters, data processing, image corrections and scripting. Pixet has an open architecture (not open source) supporting various types of imaging detectors and related devices (e.g. control of positioning systems or X-ray tubes) and allowing integration of user plug-in modules prepared in C++. Many of such plugins already exists, e.g. Timepix chip equalization, calibration, beam-hardening correction, flat-field correction, particle track analysis, scripting in Python with syntax highlighting. Pixet is written in C++ language and uses multi-platform Qt libraries.

Installation

Microsoft Windows

The PIXet for Windows is distributed as a single setup.exe file for automatic installation. For automatic installation just double-click the setup.exe and follow the instruction in the setup wizard.

In order to communicate with most of the devices, the PIXet needs the device drivers to be installed. In newer versions of Microsoft Windows, the drivers are installed automatically when the device is connected the first time. In a case that the drivers are not installed automatically, the drivers installation file Drivers/setup.exe is included in the distribution of the PIXet.

Mac OS X

The PIXet for Mac OS X system is distributed as a standard DMG file (disk image file). To install the Pixet, mount (double-click) the pixet.dmg file. A window with the disk content will open. To install, just move the Pixet folder to the Application folder.

There is no need to install a special driver for the devices. The software might ask first time it is launched after a reboot of the computer to unload Apple driver. The Apple driver is not compatible with our devices. Just click on the unload.

Linux

The Pixet for Linux system is distributed as a single tar file. To install, just untar the file. The software is launched by executing the pixet.sh script.

There is no need to install a special driver for the devices. In order to run the software under normal user, it is necessary adjust the permissions of our USB devices in udev system. This can be done by executing the script install_driver_rules.sh. It is also sometimes necessary to unload the system ftdi_sio driver. Just execute rmmod ftdi_sio as root in shell before running the software.
