Crate canparse[−][src]
A CAN signal and definition parser, written in Rust.
The goal of canparse is to provide a means of converting CAN frames into
pre-defined signals, via CANdb definition input (DBC).
One common application is the J1939
spec, which defines a set of common parameters for heavy-duty trucks and other vehicles.
PgnLibrary
is also included as an application of DBC, to give first-class support for
the PGN/SPN schema.
Example
For a predefined DBC file, a simple program which utilizes PgnLibrary
can be
implemented as folows:
extern crate canparse; use canparse::pgn::{PgnLibrary, SpnDefinition, ParseMessage}; fn main() { // Parse dbc file into PgnLibrary let lib = PgnLibrary::from_dbc_file("./j1939.dbc").unwrap(); // Pull signal definition for engine speed let enginespeed_def: &SpnDefinition = lib .get_spn(&"Engine_Speed".to_string()).unwrap(); // Parse frame containing engine speed let msg: [u8; 8] = [0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77, 0x88]; let engine_speed: f32 = enginespeed_def.parse_message(&msg).unwrap(); println!("Engine speed: {}", engine_speed); }
