CD/Digital Bundles: Many FS80 or FS88 scanners come with a basic software package that includes the necessary DLLs and sample projects to get started. Key Components of the SDK
When you extract your download, you will typically find several key folders that facilitate development:
Drivers: The low-level software required for the OS to recognize the FS series scanners.
Include/Lib Files: C++ headers and library files (.lib, .dll, or .so) needed for linking the SDK to your application.
Sample Code: Ready-to-run projects in C#, VB.NET, Java, and C++ that demonstrate enrollment and identification workflows.
Documentation: Detailed PDF manuals explaining the API functions, error codes, and hardware specifications. Installation and Setup Guide
To begin using the Futronic SDK 4.2 in your development environment, follow these general steps: 1. Install Hardware Drivers Administrator privileges on the host machine
Before coding, ensure your scanner is recognized by your machine. Plug in your Futronic device and install the drivers provided in the SDK package. Verify the device appears in the "Universal Serial Bus controllers" section of your Device Manager. 2. Configure Your IDE For Windows developers using Visual Studio:
Add the SDK's Include directory to your project's "Additional Include Directories."
Link the ftrScanAPI.lib or ftrSetApi.lib in your project settings.
Ensure the corresponding .dll files are placed in your application’s output folder (where the .exe resides). 3. Initialize the Device
Use the provided API calls to open a handle to the scanner. A typical workflow involves: ftrScanOpenDevice(): To initialize the scanner. ftrScanGetFrame(): To capture a raw fingerprint image.
ftrScanCloseDevice(): To release the hardware once the task is complete. Troubleshooting Common Issues
Device Not Found: Ensure the drivers are correctly installed and the USB cable is functional. Check if other biometric software is "locking" the device.
Library Mismatch: Ensure you are using the 32-bit (x86) libraries for 32-bit applications and 64-bit (x64) libraries for 64-bit applications. Mixing these will cause "DLL not found" or "Bad Image Format" errors.
Low Image Quality: Clean the scanner glass with a lint-free cloth. Adjust the "Finger Detection" sensitivity settings within the SDK parameters if the environment is particularly dry or humid. Conclusion
