CAN

This page documents the [can] configuration section.

This section contains the parameters needed for the device to be able communicate on the CAN-bus.

Default

[can]
bitrate = 0                     ; CAN-bus bit rate (DEC), 0 = auto-detect
silent = false                  ; Listen-only mode

Fields explained

bitrate

Configures the CAN-bus bit-rate to use. If set to zero (0), the device attempts to auto-detect (see CAN-bus for a list of detectable bit-rates) CAN-bus the bit-rate. Otherwise, the field specifies the bit-rate to use in bit/s.

Type

Minimum

Maximum

Example

Integer

5000[1]

1000000

250000

Note

Bit-rate auto-detect requires that at least two nodes communicate on the CAN-bus. Auto-detect cannot be used if only the device and a single node are connected to the CAN-bus.

silent

When silent-mode is enabled, the device logs CAN-bus traffic without interfering with the bus, i.e. the device does not acknowledge (ACK) messages placed on the CAN-bus by other devices.

Type

Options

Boolean

true, false

  • true: Silent-mode enabled

  • false: Silent-mode disabled

Note

Enabling silent-mode requires that another node on the network acknowledges messages

Warning

It is recommended to enable (true) silent-mode when possible
