Description:
Fingerprint processing includes two parts: fingerprint enrollment and
fingerprint matching (the matching can be 1:1 or 1:N)
When enrolling, the user needs to enter the finger two times. The system will
process the two-time finger images, generate a template of the finger based on
processing results, and store the template. When matching, the user enters the
finger through the optical sensor, and system will generate a template of the
finger and compare it with templates of the finger library. For 1:1 matching,
the system will compare the live finger with a specific template designated in
the Module; for 1:N matching, or searching, the system will search the whole
finger library for the matching finger. In both circumstances, the system will
return the matching result, success, or failure.
R301T capacitive fingerprint module adopts imported capacitive small-face
acquisition chip, integrated fingerprint algorithm chip, fingerprint entry,
image processing, feature extraction, template generation, template storage,
fingerprint comparison (1:1), or fingerprint search (1:1) And other functions,
with finger sensor output.
Via the serial interface, the Module may communicate with MCU of 3.3V or 5V
power: TD (pin 3 of P1) connects with RXD (receiving pin of MCU), RD (pin 4 of
P1) connects with TXD (transferring pin of MCU). Should the upper computer (PC)
be in RS-232 mode, please add a level converting circuit, like MAX232, between
the Module and PC.
The mode of Serial communication protocol is semiduplex asynchronism serial
communication. And the default baud rate is 57600bps.
Users may set the baud rate in 9600～115200bps. Transferring frame format is 10
bit: the low-level starting bit, 8-bit data with the LSB first, and an ending
bit. There is no check bit.
