Detailed Description

A demo/test/diagnostic program that uses the EDT PCI DV (pdvlib) and DMA library (edtlib) to acquire and save single or multiple images from device connected to EDT PCI DV high speed interface.

The utility has a large number of options for different ways of acquiring and saving data, tuning the acquire in various ways, and testing and diagnosing acquisition problems. Some of the methods used are quite esoteric, some are obsolete for current hardware but remain for historic purposes. As a result, take is a primary test/diagnostic application and while the code can be referred to for examples of various methods, it is not really the best example code for user applications. For more useful sample code, see simple_take.c, simplest_take.c and the users guide.
