I want to use for example the M8784Open() command to control an M8784
photon counter. I know how to place a call library function node
but don't know where to go there. The user manual for the photon
counter has the following explanation of the M8784Open() command but I
don't know how to use their advice in labview!
7-3-1 M8784Open( )
Declaration HANDLE M8784Open( BYTE Board );
Parameter
BYTE Board
Specify the board to be used: M8784_MASTER or M8784_SLAVE. Specify both
when making 2-channel measurements simultaneously. It is not possible
to specify M8784_SLAVE only.
Return value A handle for the M8784 is returned when the function has succeeded..
INVALID_HANDLE_VALUE is returned if the function has failed..
Explanation Calls a handle to allow the M8784API.dll to use the M8784.sys driver.
Hereafter, specify this API’s return value (handle) when using other APIs.
When quitting M8784 operation, call up M8784Close( ) to cancel the driver.
