srec_emon52 - Elektor Monitor (EMON52) file format
DESCRIPTION
This format is used by the monitor EMON52, developed 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 separated 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 separated 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 separated from
each other (and the checksum) by a space.
ssss Data Checksum, adding all bytes of the data line 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
