signal_parser.c and signal_parser.h.
The signal parser interface has suffered major changes. The decode functions
now take the fcp_signal_t struct as a parameter instead of individual start,
length, scale and offset parameters.
typedef struct _signal {
uint16_t start;
uint16_t length;
double scale;
double offset;
fcp_type_t type;
fcp_endianness_t endianness;
} fcp_signal_t;
The fcp_signal_t now includes the signal type and endianness. Check the
fcp_type_t and fcp_endianness_t enums for possible values.
Example usage:
uint64_t value = fcp_decode_signal_uint64_t(msg,
(fcp_signal_t) {
.start = start,
.length = length,
.scale = scale,
.offset = offset,
.type= type
.endianness = endianness
}
);
The obvious advantage of this change is the support for big endian signals.
The fcp c_gen command was updated to make use of the new signal_parser
functions.
Those that make use of c_gen should not notice any changes except for a
substantial increase in program size.
If this increase in program size is troublesome remember that the compilation of devices can be stopped by defining: NO_DCU, NO_MASTER, NO_IIB, ...
This release was a bit rushed due to the need to support big endian values in Xsense. If you encounter any problems with decoding and encoding fcp signals please notify me via discord.

- Rename fcp_v2 to idl
This release contains some bugfixes, small improvements and introduces fcp_v2 the new description language that replaces the fcp json specification format.
For now fcp commands support both the json specification format and fcp_v2.
Expect more information regarding fcp_v2 in future releases.
- Non multiplexed signals belonging to messages with other signals that are multiplexed are no longer interpreted as multiplexed signals in the decoding process.
Fcp has moved on to the next stage of its life. We've started development on the affectionately named "fcp v2".
There's a couple main goals for the new fcp version:
- Develop an IDL (interface description language) to replace the old json configuration.
- Allow fcp to generate code that works for protocols other than CAN bus.
- Extend the information that fcp is capable of encoding.
IDL example:
Documentation can be found in: https://fcp-core.readthedocs.io/en/latest/.
