CAN[edit | edit source]
Description[edit | edit source]
The CAN interface is optionally available on UNICA SBC at the connector J18.: the availability depends on the SOM installed (and to the SoC peripheral presence).
J18 is a Phoenix 1844223 MC 1,5/ 3-G-3,5 3 pins 3.5mm connector.
CAN interface is connected to the SoC CAN controller (if available in the system-on-chip).
Signals[edit | edit source]
The following table describes the interface signals:
| Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|
| 1 | CAN_H | CAN_P | |
| 2 | CAN_L | CAN_M | |
| 3 | DGND | Ground | connected to DGND |
Device mapping[edit | edit source]
CAN devices are typically mapped to the can0 device in Linux. The device mapping depends on the device tree configuration.
Device usage[edit | edit source]
The peripheral can be configured using ifconfig and ip link utilities and can be tested with the can-utils utilities.
