The Software Library

       The phoenix interface hardware can be considered as an extension to the PC through the Parallel Port providing the following features

The software to access the interface is written in both DOS and GNU/Linux platforms. Under DOS There is a library written in TurboC but it is better to develop applications under GNU/Linux. Most of the experiments need to measure the Analog and Digital Inputs as a function of time and GNU/Linux gives access to the internal CPU timer providing microsecond accuracy. Under GNU/Linux the software development tools and scientific libraries and software required for the further processing of experimental data is available. The software is arranged as shown in the figure.
    Software for new experiments can be written using the library without going into the hardware details.
The device driverC library,  python library (contributed by Pramode C.E.) and several test programs along with an installation script are inside 'phoenix.tgz'.  To install the software login as root user and untar this file from the directory '/usr' . Change to the newly created directory named 'phoenix' and run the script ''. Then go to the subdirectories to run the application programs. Here is an example program to digitize a waveform. Using Phoenix with Python is explained in an article by Pramod.
