Polaris Viewer Software


Note: The Polaris Download page contains links to Datasheets, Manuals, Application Notes and Articles.

Polaris Viewer is a graphical user interface written using IGOR from Wavemetrics (www.wavemetrics.com). It calls the user-accessible functions in the Polaris driver to carry out the communication between the Polaris board and the interface. This graphical interface can be used to configure the Polaris board, to start, poll and stop a data acquisition run, or to display list-mode or MCA data read out from the Polaris board.

The Polaris driver code comprises of a set of functions written in ANSI C. This driver was organized into a library through which Polaris users can call a few user accessible functions to implement the communication between the host and the Polaris board. These functions translate physical quantities (number with SI units) into the bit patterns understood by the Polaris's on-board processors. This provides an easy-to-use interface for Polaris users to integrate the Polaris into their own data acquisition system. Sample code showing how to initialize or configure the Polaris board, how to start or stop a run, and how to read data out of the Polaris will be provided to the users.
