[[!meta title="USB-CAN1 Board and LinCAN Support"]]

The USB-CAN implements support for USB to CAN converters developed
at [Control Engineering Department][dce] of the [Czech Technical University][ctu].

The project includes embedded software/firmware of the USB-CAN converter as well
as Linux kernel side support (for both [[LinCAN|lincan]] driver and SocketCAN found in Linux mainline now).

LPC2148+SJA1000 and LPC1768 based hardware is supported by firmware which
is based on [[LinCAN|lincan]] driver sources adapted to run on bare MCU hardware.

The firmware sources are included in can-usb1 branch of [[LinCAN|lincan]] GIT repository.

    git clone --branch can-usb1 git://git.code.sf.net/p/ortcan/lincan
    cd lincan

Edit build-embedded.sh to select required target board. The default select LPC2148+SJA1000
configuration. Change to next for LPC1768 based board

    BUILD_DIR=embedded-build/lpc1768
    OMK_CONFIG=embedded/board/arm/lpc17xx-common/config/config.usbcan

The firmware can be found in appropriate build output directory

    embedded-build/lpc1768/_compiled/bin

ARM GCC cross-compiler is required to build the project. arm-elf- compiler
tool-chain build instruction and binaries can be found
at [RTIME Cross-Compilers page][rtime-cross-compiler].

The uLAN USB boot block is expected by default LPC1768 firmware build
for for firmware flashing and startup but variant for direct startup
can be compiled as well.

SocketCAN Linux side support is included in branch vanekjir branch of
[Real-Time Systems group][rtime]'s clone of [SocketCAN GIT][rtime-socketcan-devel].
