Signal definition examples for CAN type

In the examples below, signal definitions that convert CAN data to physical values are registered.

These examples assume the following CAN data (this data definition is fictitious and does not exist).

CAN ID	Data name	startbit	bitsize	scale	offset
330 (0x0000014A)	Brake on-off	1	1	1	0
330 (0x0000014A)	Accelerator	2	8	0.3	0

Overview of the signal definitions

Item	Setting contents
Type of time series data to be converted	intdash.DataType.can
Conversion to be applied	intdash.ConversionNumFixedPoint

Register signal definitions

Create an access object for signal definitions.

import intdash

client = intdash.Client(
    url = "https://example.intdash.jp",
    edge_token = "your_token",
)

sig = client.signals

Register each signal definition as shown below.

Brake on-off

s = sig.create(
    label="BRAKE_ONOFF",
    data_type=intdash.DataType.can,
    data_id="0000014A",
    channel=1,
    conversion=intdash.ConversionNumFixedPoint(
        startbit=1,
        bitsize=1,
        endian="little",
        sign="unsigned",
        scale=1,
        offset=0,
    ),
    display=intdash.Display(
        unit="",
        min=0,
        max=1,
        format="%0.0f",
    ),
)

Accelerator

s = sig.create(
    label="ACCEL",
    data_type=intdash.DataType.can,
    data_id="0000014A",
    channel=1,
    conversion=intdash.ConversionNumFixedPoint(
        startbit=2,
        bitsize=8,
        endian="little",
        sign="unsigned",
        scale=0.3,
        offset=0,
    ),
    display=intdash.Display(
        unit="",
        min=0,
        max=100,
        format="%0.0f",
    ),
)
