I am trying to create an application with remote controlling a Fingerprint sensor (Guide included on link) for enrolling and identifying fingerprints on are Raspberry PI 3 Model. There is a SDK_DEMO for this particular functionality on Windows only, which you can find in the Guile I mentioned above.
- SDK_DEMO is written in C++ on Visual studio so I can't manipulate the code to run it on Raspberry Pi 3.
From the SDK_DEMO source code I figured out which command I need to send to execute tasks.
CMD_NONE = 0x00, CMD_OPEN = 0x01, CMD_CLOSE = 0x02, CMD_USB_INTERNAL_CHECK = 0x03, CMD_CHANGE_BAUDRATE = 0x04, CMD_MODULE_INFO = 0x06, CMD_CMOS_LED = 0x12, CMD_ENROLL_COUNT = 0x20, CMD_CHECK_ENROLLED = 0x21, CMD_ENROLL_START = 0x22, CMD_ENROLL = 0x23, CMD_ENROLL1 = 0x23, CMD_ENROLL2 = 0x24, CMD_ENROLL3 = 0x25, CMD_IS_PRESS_FINGER = 0x26, CMD_DELETE = 0x40, CMD_DELETE_ALL = 0x41, CMD_VERIFY = 0x50, CMD_IDENTIFY = 0x51, CMD_VERIFY_TEMPLATE = 0x52, CMD_IDENTIFY_TEMPLATE = 0x53, CMD_CAPTURE = 0x60, CMD_GET_IMAGE = 0x62, CMD_GET_RAWIMAGE = 0x63, CMD_GET_TEMPLATE = 0x70, CMD_ADD_TEMPLATE = 0x71, CMD_GET_DATABASE_START = 0x72, CMD_GET_DATABASE_END = 0x73, CMD_FW_UPDATE = 0x80, CMD_ISO_UPDATE = 0x81, CMD_FAKE_DETECTOR = 0x91, CMD_SET_SECURITY_LEVEL = 0xF0, CMD_GET_SECURITY_LEVEL = 0xF1, ACK_OK = 0x30, NACK_INFO = 0x31,
SKD_DEMO recognised the FingerPrint sensor as Mass Storage and somehow was running the commands like that.
In Ubuntu though when I plug in the usb device I don't get any Mass storage mounting and on
lsusb I get this:
I have be searching about this and tried to
echo "0x12" >> /dev/bus/usb/001/008
But I got a write error for invalid argument.
Here are the terminal commands for the echo attempt:
Is there a way I can send raw commands with this format and executing actions without needing to write a driver for this USB device on Linux?
