NAME

       srec_emon52 - Elektor Monitor (EMON52) file format

DESCRIPTION

       This  format  is  used  by the monitor EMON52, devolped by the European
       electronics magazine Elektor (Elektuur in Holland).   Elektor  wouldn't
       be  Elektor  if  they didn't try to reinvent the wheel.  It's a mystery
       why they didn't use an existing  format  for  the  project.   Only  the
       Elektor Assembler will produce this file format, reducing the choice of
       development tools dramatically.

   Records
       All data lines  are  called  records,  and  each  record  contains  the
       following four fields:

                         +---+------+---+-----------+------+
                         |cc | aaaa | : | dd ... dd | ssss |
       The field are defined-as-follows:+-----------+------+

       cc      The  byte  count.  A two digit hex value (1 byte), counting the
               actual data bytes in the record.  The byte count  is  seperated
               from the next field by a space.

       aaaa    The   address   field.   A  four  hex  digit  (2  byte)  number
               representing the first address to be used by this record.

       :       The address field and the data field are seperated by a colon.

       dd      The actual data of this record.  There can be  1  to  255  data
               bytes per record (see cc) All bytes in the record are seperated
               from each other (and the checksum) by a space.

       ssss    Data Checksum, adding  all  bytes  of  the  dataline  together,
               forming  a  16 bit checksum.  Covers only all the data bytes of
               this record.

       Please note that there is no End Of File record defined.

   Byte Count
       The byte count cc counts the actual data bytes in the  current  record.
       Usually  records  have  16  data  bytes.  I don't know what the maximum
       number of data bytes is.  It depends on the size of the data buffer  in
       the EMON52.

   Address Field
       This  is  the address where the first data byte of the record should be
       stored.  After storing that data byte, the address is incremented by  1
       to  point  to the address for the next data byte of the record.  And so
       on, until all data bytes are stored.

       The address is represented by a 4 digit hex number (2 bytes), with  the
       MSD first.

   Data Field
       The  payload  of the record is formed by the Data field.  The number of
       data bytes expected is given by the Byte Count field.

   Checksum
       The checksum is a 16 bit result from  adding  all  data  bytes  of  the
       record together.

   Size Multiplier
       In general, binary data will expand in sized by approximately 3.8 times
       when represented with this format.

EXAMPLE

       Here is an example of an EMON52 file:
              10 0000:57 6F 77 21 20 44 69 64 20 79 6F 75 20 72 65 61 0564
              10 0010:6C 6C 79 20 67 6F 20 74 68 72 6F 75 67 68 20 61 05E9
              10 0020:6C 6C 20 74 68 69 73 20 74 72 6F 75 62 6C 65 20 05ED
              10 0030:74 6F 20 72 65 61 64 20 74 68 69 73 20 73 74 72 05F0
              04 0040:69 6E 67 21 015F
