ISO TP, UDS and OBD-2

2014-11-18 • 3 API's for the Communication with Control Units


With PCAN-ISO TP, PCAN-UDS and PCAN-OBD-2 we publish 3 free programming interfaces for standardized protocols from the automotive sector.

PCAN-ISO-TP : API for the transfer of data packages according ISO-TP (ISO 15765-2).
ISO-TP (ISO 15765-2) is an international standard for the transfer of data packages via CAN. It can transmit data packages of up to 4095 Bytes per CAN message.

PCAN-UDS : API to communicate with control devices according UDS (ISO 14229-1).
UDS (ISO 14229-1) stands for Unified Diagnostic Services and defines the communication with control units (ECUs). UDS uses the ISO-TP standard as transport protocol.

PCAN-OBD-2 : API for the vehicle diagnostics according OBD-2 (ISO 15765-4).
For on-board diagnostics, the OBD-2 standard defines the exchange of specific vehicle parameters. As part of OBD-2, the ISO 15765-4 standard describes the CAN bus as a transmission option.

The programming interfaces use PCAN-Basic  to access the CAN hardware in the computer. All three APIs are available free of charge.
