With PCAN-ISO TP, PCAN-UDS, and PCAN-OBD-2, PEAK-System publishes three programming interfaces (APIs) for standardized protocols from the automotive sector. The APIs are designed for use under Windows and built on each other. The common basis is the PCAN-Basic API for accessing PEAK-System's CAN hardware in the computer.
The PCAN-ISO-TP API is used to transmit data packets according to the ISO-TP standard ISO 15765-2. This includes the transmission of packets up to a size of 4095 bytes per CAN message.
Via the PCAN-UDS API, a communication with control units takes place according to the UDS standard ISO 14229-1. UDS stands for Unified Diagnostic Services. UDS makes use of the ISO-TP standard as transport protocol.
With the PCAN-OBD-2 API, vehicle diagnostics are performed using OBD-2 (ISO 15765-4). This standard defines the exchange of specific vehicle parameters via UDS. As OBD-2 transmission option, the API uses the CAN bus.
All three APIs are available free of charge and can be downloaded from the PEAK-System website.
