2：Supported Features​

  • Supports writing serial number to any Flash block, such as Flash Memory, EEPROM, OTP, etc.

  • Big number support 1~64 (not enough can continue to increase) bytes of sequence number writing, you can freely configure the length of the write.

  • Big number supports end-of-serial number setting to avoid duplicate serial numbers during the production process。

  • Support serial number file import (xlsx table parsing, support more than 1 million lines).

    • Serial number file import does not limit the length of the serial number.
    • Serial number file import supports big number writes.
    • Serial number file import supports writing of very long strings of serial numbers.
    • Serial number file import supports setting the offset address, and the number of single imports.
    tip

    When importing from a file, the default is to import using the small end mode, with the low address on the left.

3：Big number​

Serial Number Write Address: Set the write address of the serial number, which can be freely configured.

Serial Number Length: supports 1~64 bytes length, freely configurable.

Serial Number Starting Value (Small End Mode): Sets the starting value of the serial number.

Step of sequence number (small end mode): Sets a single increment of the sequence number.

Sequence Number End Value (Little Endian Mode): Sets the end value of the sequence number.

tip

Big number is an enhancement to Power Writer's default 4-byte serial number to compensate for the following shortcomings of the default serial number:

  • Default Serial Number Function: the length is limited to four bytes.
  • Default sequence number function: no end value judgment.
  • Default Serial Number Function: No arbitrary region can be set.

4：External File Import​

External file import supports xlsx table, when importing table, you need to set the rows and columns for serial number reading, the default is to start reading from 0 rows and 0 columns.

5：Notes​

  • When importing from an external file, the cells must all be strings, if they are not strings, an error will be reported.
  • When importing serial numbers from external files, you need to ensure that the serial number length is uniform.
  • External serial number import defaults to the little endian.
