Libraries

STW provides the following libraries for development:

TAF

The Teleservice Application Framework (TAF) is the core of each teleservice application. It contains all
necessary daemons and the corresponding library to interact with the daemons.

With the TAF it is possible to:



create data loggers



manage the network



send or receive SMS



communicate with external servers

HTTP Tiny

The http tiny library extends the functionality of your application with the possibility to perform HTTP queries like
post and get. For further information please refer to the http_lib.h.

CANopen

The libraries provide an easy way to access and communicate with slave nodes like I/O extension modules.

STW devices



DIOS library: This library provides higher level functions to interact with ESX-DIOS and ESX-DIOM
modules.



IOX library: This library provides higher level functions to interact with ESX-IOX modules.

Non-STW devices

COL2 library: This CANopen Layer 2 library can be used for communication with Non-STW CANopen devices

J1939

The library provides an easy way to access j1939 nodes over CAN.
