RE-350 32bit Sample Code (\32BITSDK)

Notes:

1)This example application was written and compiled with Microsoft C/C++ and SDK Version 4.0 (32 bits ONLY). Open the project in Microsoft Visual C/C++ 4.0 to edit and recompile.

2)The RE-350driver (RE350.DLL) is located in .\EXAMPLE\RE350 and has been setup as a sub-project of EXAMPLE. It will be automatically updated if EXAMPLE is set as the project. The output is directed to the EXAMPLE\RELEASE directory so any changes made to the DLL will be automatically loaded by the application next time it is run.

EXAMPLE explicitly loads and unloads the DLL using LoadLibrary() and FreeLibrary() to facilitate this (see

EXAMPLE.C).

3)RE350.C and RE350.H constitute the basic driver and are generalized to work with any application. All of the functions return an error code (defined in RE350.H) to indicate whether the operation was successful.

Initialize communications with the RE-350:

int FAR PASCAL	RE350_Open( int iComPort )
int iComPort:	RE350_COM1-RE350_COM4
Execute an RE-350command:
int FAR PASCAL	RE350_Command( int iDevice, int nCmd, WORD wRequest, LPWORD lpwResponse );
int iDevice:	device 0-3 (check dipswitch on the back)
int nCmd:	Command defined in RE350.H.
WORD wRequest:	Request data if required by command.
	(Use RE350_NULL_REQUEST if not required).
LPWORD wRequest:Pointer to response (or NULL).
Close communications with the RE-350:
VOID FAR PASCAL	RE350_Close( VOID );

4)EXAMPLE.C is a simple application which demonstrates the operation of the driver. After getting this to compile in your environment, you can add additional commands (via RE350_Command) to test the camera’s operation.

All of the RE-350commands are implemented through this function.
