Communication stack structure and supported specifications
A communication stack consists of three layers: driver layer → stack layer → related-functions layer. Below are this product's position in the stack and the specifications it supports.
UDS services, ISO-TP.
Main uses
- Implement diagnostic functions (UDS) in an ECU
- Support reading diagnostic trouble codes, setting parameters, and reprogramming
- Implement to the diagnostic specification set by the OEM
Benefits
- The standardized service structure makes compatibility with diagnostic tools easier to ensure
- Security Access and similar services can be procured rather than implemented in-house
- Can be deployed in both CAN and Ethernet configurations
Environment
- RTOS: usable with or without an RTOS (8/16/32/64-bit CPUs)
- Supported buses: CAN / CAN FD / LIN / Ethernet (depending on product)
- Delivery: ANSI C source code / partners: TI, NXP, STMicroelectronics, Microchip
