User can only access library by template number. CharBuffer2. The host can access the page by instructions of PS_WriteNotepad and PS_Read Notepad. where data requiring power-off protection can be stored. CharBuffer1. That’s 8-bit BMP format. Note: when write on one page of the pad. the image is 8-bit pixel. Assume the fingerprint capacity N. Users can read & write any of the buffers by instructions. can be used to store both character file and template file.3 5. Buffer There are an image buffer and two 512-byte-character-file buffer within the RAM space of the module. 1. Note: Contents of the above buffers will be lost at power-off.5 V mA uA V Logic 1 Maximum input voltage IV System Resources To address demands of different customer.3V 2. Notepad The system sets aside a 512-bytes memory (16 pages* 32 bytes) for user’s notepad. Module system provides abundant resources at user’s use. Character file buffer Character file buffer. Contents of the library remain at power off. 3 … N. only the upper 4 bits of the pixel is transferred (that is 16 grey degrees). the entire 32 bytes will be written in wholly covering the original contents. to quicken speed. Image buffer ImageBuffer serves for image storage and the image format is 256*288 pixels. -5- .VIH IIH VImax VIH =5V VIH =3. 4. system will recognize the latter automatically.4 1 30 －0. When transferring through UART. And two adjacent pixels of the same row will form a byte before the transferring. Capacity of the library changes with the capacity of Flash. that’s 256 grey degrees. then the serial number of template in library is 0. 2. When uploaded to PC.3Fingerprint Library Synstem sets aside a certain space within Flash for fingerprint template storage. Fingerprint template’s storage in Flash is in sequential order. When transferring through USB. the 16-grey-degree image will be extended to 256-grey-degree format. that’s fingerprint library. -6- . That’s. 5. and can be read via instruction ReadSysPara. At level 1. Baud rate control (Parameter Number: 4) The Parameter controls the UART communication speed of the Modul. FAR is the lowest and FRR is the highest. 0FFH. Module first responses with original configurations. Security level is divided into 5 grades. Cooresponding baud rate is 9600*N bps。 Security Level (Parameter Number: 5) The Parameter controls the matching threshold value of fingerprint searching and matching. Module password At power-on reset. Both instructions take Parameter Number as parameter. 1: system is executing commands. 1: find the matching finger. 4. 0FFH. when Module password remains the default. 1: image buffer contains valid image. 3. and cooresponding value is 1. corresponding to 32 bytes. 128 bytes. Pass：1 bit. Or else. system will run with the new configurations. At the next startup. PWD：1 bit. 0FFH. however at level 5. 64 bytes. N= [1. If not. system deems upper computer has no requirement of verifying password and will enter into normal operation mode. Data package length (Parameter Number: 6) The parameter decides the max length of the transferring data package when communicating with upper computer. 1: Verified device’s handshaking password. Should the password have be modified. Definition of the register is as follows: Bit Num Description 15 4 3 ImgBufStat 2 PWD 1 Pass 0 Busy Reserved Note: Busy：1 bit. System status register System status register indicates the current operation status of the Module. Its value is 0. 256 bytes respectively. 3. and its default factory value is 0FFH. Its length is 1 word. FAR is the highest and FRR is the lowest. 2. 2. refer to instruction SetPwd. 0: system is free. And the basic instructions are SetSysPara & ReadSysPara. system will refuse to execute and command. verifying process can be jumped. 12]. When upper computer sends command to modify parameter. system first checks whether the handshaking password has been modified. The password length is 4 bytes. Its value is an integer N. ImgBufStat：1 bit. Module opens part system parameters for use.System Confiuration Parameter To facilitate user’s developing. then Module (or device) handshaking password must be verified before the system enter into normal operation mode. 1. 0: wrong finger. then performs the parameter modification and writes configuration record into Flash. Data package format Header Adder Package identifier Package length Package content (instuction/data/Parameter） Checksum Definition of Data package Name Header Symbol Start Length 2 bytes Description Fixed value of 0xEF01. Default value is 0xFFFFFFFF. Data packet shall not appear alone in executing processs. Adder Package identifier ADDER 4 bytes PID 1 byte 02H 07H -7- . The address length is 4 bytes. USB interface is strongly recommended to improve the exchanging speed. which can be modified by command. which contains the address item. Acknowledge packet. Random number generator Module integrates a hardware 32-bit random number generator (RNG) (without seed). V Communication Protocol The protocol defines the data exchanging format when ZFM-20 series communicates with upper computer. When communicating with upper computer.1Data package format When communicating. 01H Command packet. Module address Each module has an identifying address. High byte transferred first. User may modify the address via instruction SetAdder. the transferring and receiving of command/data/result are all wrapped in data package format. 5. must follow command packet or acknowledge packet. module will reject to transfer. For PC. system will generate a random number and upload it. The protocol and instruction sets apples for both UART and USB communication mode. The new modified address remains at power off. High byte transferred first and at wrong adder value. Data packet. and its default factory value is 0xFFFFFFFF.The new modified password is stored in Flash and remains at power off. Via instruction GetRandomCode. Module system only responds to data package whose address item value is the same with its identifying address. each instruction/data is transferred in data package form. especially in fingerprint scanning device. Module will report the commands execution status and results to upper computer through acknowledge packet. Acknowledge packet includes 1 byte confirmation code and maybe also the returned parameter. 10h: fail to delete the template. Package length LENGTH 2 bytes Refers to the length of package content (command packets and data packets) plus the length of Checksum( 2 bytes). 11h: fail to clear finger library. etc. And high byte is transferred first. 0Eh: Module can’t receive the following data packages. 0Bh: addressing PageID is beyond the finger library. 1Bh: incorrect configuration of register.
