SWEE File Reader/Writer

This package parses and writes the 'SWEE' file format used by Control Solutions.

Refer to the test/ folder for examples.

SWEE File Format

# Each line begins with an alphanumeric 'line type' token followed by ': '. The
# line type determines how the rest of the line will be interpreted.  Each line is
# terminated by CR, or CR/LF.  Blank lines, and anything that follows the comment
# character (#) on a line is ignored.  Whitespace at the beginning or end of line
# is ignored.  All numbers are hexadecimal unless otherwise indicated.  Decimal
# values are preceded by ".", ASCII values are indicated by enclosing in "".
#
# line types are:
#
#
# info  used for information that might be useful for programmers.  Ignored
#     during factory test programming of board.  Format should be JSON
#           compliant.
#
# data  Data lines begin with an address.  The address is either an 8 or 16
#     bit value, and always at the start of a line.  The address is identified
#       by a trailing ":" followed by white space.  Address is stored in big
#     endian format (MSB, LSB).  Unspecified leading bytes of address are
#     assume 0x00.  For compatibility with original
#     SWEE format, if the first data line does not contain an address, the rest
#     of the file is treated as sequential data bytes separated by white space
#     or CR or CR/LF, starting at address 0x00 (or 0x0300 for CANBus controllers).
#     Data bytes are single bytes separated by one or more whitespace characters.
#     If a data entry is not provided for every ee byte on a board, then
#     unspecified values should be treated as "don't care" and should not be
#     changed when this file is loaded.

#
#   Locations 0x00f3, 0x00f4, and 0x00f5 below shall contain the EE file identifier,
# and contain the SWEE part number from Agile that corresponds to this default file,
# as well as a bit flag to indicate this is a customer generated file.  This identifier
#   is used for programming apps to select the proper EE file for the factory default
# operation if selected by the user.  Encoding is as follows:
#
#   0x00f4  High byte of SWEE number converted to hex
#   0x00f5  Low byte of SWEE number converted to hex
#   0x00f3  ASCII representation of SWEE rev.  High bit is set to indicate
#       the customer generated the default file and factory default function
#       from programming app should not attempt to load CS default file
