Constructor for the FirewireDCAM class Initialises the camera object by setting all the default parameters and initializing the camera hardware with it.
This function also reads out the current settings of the camera and prints out a selection of parameters to the shell.
portName | The asyn port name to give the particular instance. |
camid | The unique ID stored in the camera. |
speed | The bus speed to use this camera at. Can be 800[Mb/s] for 1394B mode or 400[Mb/s] for 1394A mode. |
maxBuffers | The largest number of image buffers this driver can create. |
maxMemory | The maximum amount of memory in bytes that the driver can allocate for images. |
disableScalable | Disable scalable (format 7) modes if this is 1 |
