fingerprint-reader

WaveShare UART Fingerprint reader for use of raspberry pi

Protocol Align

• Dormant State
• Set / Read mode
  • (repeat mode / prohibit mode)
• Add Fingerprint
  • must 3 times input(required send command)
  • user number range 1 - 0xFFF(4095)
  • user ID and user privilege should be same
• Delete User
• Delete All Users
• Acquire the total number of users
• Compare 1:1
• Compare 1:N
• Acquire user privilege
• Acquire DSP module version
• Set Read Comparison level (level range is 0-9, default 5)
• Acquire and upload images
• Upload acquired images and extract eigenvalue
• Download eigenvalues and acquire fingerprint comparison
• Download the fingerprint eigenvalues and DSP module database fingerprint compare 1:1
• Download the fingerprint eigenvalues and DSP module database compare 1:N
• Upload the DSP module database specified user eigenvalue
• 18. Download the eigenvalue and save to the DSP module database according to the specified user number
• 19. Acquire all logged in user numbers and user privilege
• 25. Set/Read fingerprint capture timeout value
  • Range of waiting timeout value is 0-255 (0 is wait infinitely or time * 0.2s)

Process

• Add
  • Start
    • 1st Cycle
      • Check Database ; if not: Return Q3=ST_FULL
      • Collect Fingerprint ; if not: Q3=ST_TIMEOUT
      • Image Processing ; if not: Q3=ST_FAIL
      • If yes; Q3=ST_SUCCESS
    • 2nd
      • Collect Fingerprint
      • Image Processing
      • OK
    • 3th
      • Collect Fingerprint
      • Image Processing
      • Check Unique FP(only prohibit); Q3=ST_USER_EXIST
      • Add FP database
      • Q3=ST-SUCCESS
• Delete
• Delete All
• Upload Image and Extract eigenvalue
  • Collect
  • Img Process
  • Return data with eigenvalue
