Syntax
INT is_DeviceFeature (HIDS hCam, UINT nCommand, void* pParam, UINT cbSizeOfParam)
Description
Using is_DeviceFeature() you can configure special camera functions provided by specific uc480
models:
DCC3260
By using the level-controlled trigger, you can control the exposure time directly via the duration of
the trigger signal.
The level controlled trigger cannot be used in combination with the software trigger
mode, trigger prescaler, or the AOI merge mode.
The nCommand input parameter is used to select the function mode. The pParam input parameter
depends on the selected function mode. If you select functions for setting or returning a value,
pParam contains a pointer to a variable of the UINT type. The size of the memory area to which
pParam refers is specified in the cbSizeOfParam input parameter.
