-# OpenXC Message Format Specification
+# CAN signaling binder
-This specification is a part of the [OpenXC platform][OpenXC].
+CAN bus binder, based upon OpenXC vi-firmware project.
-An OpenXC vehicle interface sends generic vehicle data over one or more output
-interfaces (e.g. USB or Bluetooth) as JSON objects, separated by newlines.
+Full document can be found under `docs` directory.
-There are two valid message types - single valued and evented.
+# Fast build procedure
-There may not be a 1:1 relationship between input and output signals - i.e. raw
-engine timing CAN signals may be summarized in an "engine performance" metric on
-the abstract side of the interface.
+Just use autobuild script:
-## Single Valued
-
-The expected format of a single valued message is:
-
- {"name": "steering_wheel_angle", "value": 45}
-
-## Evented
-
-The expected format of an event message is:
-
- {"name": "button_event", "value": "up", "event": "pressed"}
-
-This format is good for something like a button event, where there are two
-discrete pieces of information in the measurement.
-
-## Raw CAN Message format
-
-An OpenXC vehicle interface may also output raw CAN messages. Each CAN message
-is sent as a JSON object, separated by newlines. The format of each object is:
-
- {"bus": 1, "id": 1234, "value": "0x12345678"}
-
-**bus** - the numerical identifier of the CAN bus where this message originated,
- most likely 1 or 2 (for a vehicle interface with 2 CAN controllers).
-
-**id** - the CAN message ID
-
-**data** - up to 8 bytes of data from the CAN message's payload, represented as
- a hexidecimal number in a string. Many JSON parser cannot handle 64-bit
- integers, which is why we are not using a numerical data type.
-
-## Trace File Format
-
-An OpenXC vehicle trace file is a plaintext file that contains JSON objects,
-separated by newlines.
-
-The first line may be a metadata object, although this is optional:
-
-```
-{"metadata": {
- "version": "v3.0",
- "vehicle_interface_id": "7ABF",
- "vehicle": {
- "make": "Ford",
- "model": "Mustang",
- "trim": "V6 Premium",
- "year": 2013
- },
- "description": "highway drive to work",
- "driver_name": "TJ Giuli",
- "vehicle_id": "17N1039247929"
-}
+```bash
+./conf.d/autobuild/agl/autobuild build
+./conf.d/autobuild/agl/autobuild package
```
-The following lines are OpenXC messages with a `timestamp` field added, e.g.:
-
- {"timestamp": 1385133351.285525, "name": "steering_wheel_angle", "value": 45}
-
-The timestamp is in [UNIX time](http://en.wikipedia.org/wiki/Unix_time)
-(i.e. seconds since the UNIX epoch, 00:00:00 UTC, 1/1/1970).
-
-## Official Signals
-
-These signal names are a part of the OpenXC specification, although some
-manufacturers may support custom message names.
-
-* steering_wheel_angle
- * numerical, -600 to +600 degrees
- * 10Hz
-* torque_at_transmission
- * numerical, -500 to 1500 Nm
- * 10Hz
-* engine_speed
- * numerical, 0 to 16382 RPM
- * 10Hz
-* vehicle_speed
- * numerical, 0 to 655 km/h (this will be positive even if going in reverse
- as it's not a velocity, although you can use the gear status to figure out
- direction)
- * 10Hz
-* accelerator_pedal_position
- * percentage
- * 10Hz
-* parking_brake_status
- * boolean, (true == brake engaged)
- * 1Hz, but sent immediately on change
-* brake_pedal_status
- * boolean (True == pedal pressed)
- * 1Hz, but sent immediately on change
-* transmission_gear_position
- * states: first, second, third, fourth, fifth, sixth, seventh, eighth,
- ninth, tenth, reverse, neutral
- * 1Hz, but sent immediately on change
-* gear_lever_position
- * states: neutral, park, reverse, drive, sport, low, first, second, third,
- fourth, fifth, sixth, seventh, eighth, ninth, tenth
- * 1Hz, but sent immediately on change
-* odometer
- * Numerical, km
- 0 to 16777214.000 km, with about .2m resolution
- * 10Hz
-* ignition_status
- * states: off, accessory, run, start

-* fuel_level
- * percentage
- * 2Hz
-* fuel_consumed_since_restart

- restarts, like a trip meter)
- * 10Hz
-* door_status
- * Value is State: driver, passenger, rear_left, rear_right.
- * Event is boolean: true == ajar
- * 1Hz, but sent immediately on change
-* headlamp_status
- * boolean, true is on
- * 1Hz, but sent immediately on change
-* high_beam_status
- * boolean, true is on
- * 1Hz, but sent immediately on change
