Projects

• Virtual CAN API
• CAN Project : The CAN projects aim is to develop and maintain a CAN driver for Linux/windows that support misc. can chips/cards. Also utilities such as tracing tools, diagnostic tools and such will be published in the project. The Very Simple Control Protocol (VSCP)
• CANpie : This project defines a Standard API for access to the CAN (Controller Area Network) bus. The API provides functionality for ISO/OSI Layer-2 (Data Link Layer). The CANpie driver is the base for HLPs like CANopen, DeviceNet, J1939 etc.

Protocols

• SAE J1850 PWM (41.6 kbaud)
• SAE J1850 VPW (10.4 kbaud)
• ISO 9141-2 (5 baud init, 10.4 kbaud)
• ISO 14230-4 KWP (5 baud init, 10.4 kbaud)
• ISO 14230-4 KWP (fast init, 10.4 kbaud)
• ISO 15765-4 CAN (11 bit ID, 500 kbaud)
• ISO 15765-4 CAN (29 bit ID, 500 kbaud)
• ISO 15765-4 CAN (11 bit ID, 250 kbaud)
• ISO 15765-4 CAN (29 bit ID, 250 kbaud)
• ISO 15765-4 CAN (29/11bit ID, arbitrary baudrate)
• SAE J1939

VCSP

Sur le site de VCSP, les mecs se sont intéressés à l’interface CAN. Si j’ai bien compris, il a plusieurs composants :

• CANALD : un deamon qui rebalance les info sur un socket TCP/IP
• VCSP
• CAN Abstraction Layer : couche basse (DLL Driver)

• VSCP/CANAL, Getting started.
• the VSCP Specification - This is how it all works
• CANAL/VSCP Drivers - Drivers for different equipment and technologies using the CANAL interface.
