sci library
The Simple CAN Interface (SCI) is an API that was developed with MultiCAN, see also socan and MultiCAN.
socan implements all functions of SCI that are needed by MultiCAN.
The sci library is built on top of the socan library and has many features in common with it:
CAN ports
Definition of CAN Objects with optionally associated user data
Filtering of CAN Objects
Timestamp support
Blocking and non-blocking read- and write functions for single CAN Objects.
Implementation of RTR CAN frames with automatic generation of replies to incoming RTR frames.
One reader and one writer thread for each CAN port.
A command line test program, “scitest”, that is used to test the library.
Notable functions of the sci library not present in the socan library are:
Plugins. The application can define functions that modify CAN data and optionally change the length of the data block before it it sent to the CAN bus. It can also define other functions that modify CAN data and optionally change the data block length when it is received from the CAN bus. This feature is probably rarely needed, it was implemented out of necessity to communicate with CAN devices that were not standard compliant.
Duplicated CAN objects, these are objects with the same properties as other existing CAN Objects, but have different associated user data.
