Communication between user application and
PowerDAQ board
Figure 16: Communication between user application and
PowerDAQ board
DSP – Digital Signal Processor controls all on board devices. User
application communicates with the board via the PowerDAQ API
encompassed into the PowerDAQ dynamic-link library (DLL). To inform
application about hardware events, the driver creates Win32 events.
Data is transferred from the board through the PCI bus and stored in
the user-level buffer. The PowerDAQ API includes a set of information
functions which allow user applications to get board-specific
information such as model , serial number, IRQ line, etc.
