The file SM630Commands.cs allows you to communicate with the SM630 Fingerprint module in your C#/Arduino based projects.

1. This is a C# implementation of the Arduino commands for the SM630 fingerprint module.
2. An understanding of the SM630 fingerprint Arduino library is recommended.
3. An understanding of C# is recommended so as to modify the .cs file to suit your need.

The module communicates via the serial port. Most PCs do not come with serial ports again. However, a USB to serial converter can be used instead.

1. bool AddFingerprint(int id): Adds a fingerprint template to a specified ID. Returns true if success else false.
2. bool DeleteFingerprint(int id): Deletes stored fingerprint template at a specified ID. Returns true if success else false.
3. bool EmptyDatabase(): Deletes all saved fingerprint templates on the device. Returns true if success else false.
4. bool UploadTemplate(int id, byte[] templ): Uploads an already acquired template to a specified ID on the module. Returns true if success else false.
5. string ToHex(int value): Converts value to hexadecimal string to be used by the fingerprint module
6. int FromHex(string value): Converts hexadecimal string back to hex.
