Serial-Line CAN Microservice

Overview

slcan-svc is a go-kit based microserivce impelementation which is capable of bridging serial-line CAN communication via RESTful APIs. The serial-line backend of the service is partially Serial-Line CAN compliant for interfacing a slcan end device.

slcan-svc could interact with mcumgr-svc using RabbitMQ to perform Device Firmware Update. See demo-svc for the detail.

Building and Running

Clone and build slcan-svc repository:

cd /workdir/slcan-svc
go build -o ./build/cli ./cli

Get slcan-svc usage:

./workdir/build/cli -h

-p string
        SLCAN port
-u string
        AMQP dialing address (default "amqp://guest:guest@localhost:5672/")

Run slcan-svc with serial port specified:

./workdir/build/cli -p /dev/ttyACM0
