README
An incomplete driver for the HZ Grow R502 fingerprint reader module
Uses embedded-hal and arrayvec. It's not intended to be a complete implementation of the
R502 command set but rather enough for a simple fingerprint verification device.
Feature support
- Authenticating with the device and querying status
- Searching the fingerprint library
- Verifying selected fingerprints
- Enrolling and deleting fingerprints
For more, see the projects.
Examples
Some examples are meant to be run on a full PC rather than an embedded device. Use a serial to USB converter at 3.3V power and logic levels. I recommend the ESP-PROG.
Contributing guidelines
If you want to send a PR, please make sure that your changes work on a real R502 (if your changes modify anything in the driver itself). For issues, do a cursory check to see if a similar issue has already been filed.
