NAME
srec_ascii_hex - Ascii[hy]Hex file formatDESCRIPTION
This format is also known as the Ascii[hy]Space[hy]Hex or Ascii[hy]Hex[hy]Space format. If you know who invented this format, please let me know. If you have a better or more complete description, I'd like to know that, too.The file starts with a start[hy]of[hy]text (STX or Control[hy]B) character (0x02). Everything before the STX is ignored.
Each data byte is represented as 2 hexadecimal characters, followd by an "execution character". The default execution character is a space, although many programs which write this format omit the space character immediately preceeding end[hy]of[hy]line.
The address for data bytes is set by using a sequence of CW]$ACI]nnnnCW], characters, where nnnn is the 4[hy]character ascii representation of the address. The comma is required. There is no need for an address record unless there are gaps. Implicitly, the file starts a address 0 if no address is set before the first data byte.
The file ends with an end[hy]of[hy]text (ETX or Control[hy]C) character (0x03). Everything following the ETX is ignored.
It is also possible to specify a running 16[hy]bit checksum using a sequence of CW]$SCI]nnnnCW], characters, although this usually appears after the ETX character and is thus often ignored.
Variant Forms
In addition to a space character, the execution character can also be percent (%) called "ascii[hy]hex[hy]percent" format, apostrophe (') or comma (,) called "ascii[hy]hex[hy]comma" format. The file must use the same execution character throughout.If the execution character is a comma, the address and checksum commands are terminated by a dot (.) rather than a comma (,).
Size Multiplier
In general, binary data will expand in sized by approximately 3.0 times when represented with this format.EXAMPLE
Here is an example ascii[hy]hex file. It contains the data [lq]Hello, World[rq] to be loaded at address 0x1000.-
