vscpl1drv-socketcan - VSCP Level I Socketcan Driver

Level I driver for Linux Socketcan. SocketCAN, the official CAN API of the Linux kernel, has been included in the kernel for many years now. Meanwhile, the official Linux repository has device drivers for all major CAN chipsets used in various architectures and bus types. SocketCAN offers the user a multiuser capable as well as hardware independent socket-based API for CAN based communication and configuration. Socketcan nowadays give access to the major CAN adapters available on the market.

Note that as CAN only can handle Level I events only events up to class < 1024 can be sent to socketcan devices.

cd vscpl1drv-socketcan
git submodule update --init
./configure
make
make install

Default install folder is /var/lib/vscp/drivers/level1

You need build-essentials and git installed on your system.

sudo apt update && sudo apt -y upgrade
sudo apt install build-essential git

There are many Level I drivers (CANAL drivers) available in VSCP & Friends framework that can be used with both VSCP Works and the VSCP Daemon (vscpd) and other tools that interface the drivers using the CANAL standard interface. Added to that many Level II and Level III drivers are available that can be used with the VSCP Daemon.

Level I drivers is documented here.

Level II drivers is documented here

The VSCP project homepage is here https://www.vscp.org.

The manual for vscpd contains full documentation. Other documentation can be found on the documentaion portal.
