The TEM-DAQ board is a VME board. A National Instrument VME-PCI8026 interface is used to connect a PC with the VME bus. The PC runs Linux as operating system.
The user interface to the DAQ system is written in Python. However, in order to access the VME bus the C-library, nivxi , provided by Nat. Instr. has to be used. This is done by writing C-functions, specific for the TEM and wrap wrap them into python so that they are callable directly from the python interpreter. The module is called tkrTem .
In order to run the TEM DAQ the user is writing Python scripts or modules, which are executed from within the python interpreter. Scripts are execute using the execfile command, modules are imported and the imported functions or classes are called.
