ISO 15765 Software Protocol Stack FAQ

What is a ISO 15765 protocol stack?
A ISO 15765 protocol stack, also known as middleware, is a software library which converts between individual CAN frames and complete ISO 15765 messages.

Which CPUs and microcontrollers does your protocol stack support?
Our ISO 15765 software is written entirely in the ANSI C programming language and is completely platform independent. This means it will work will all CPUs and microcontrollers. The target specific code is handled by the CAN device driver. See available ports on our main ISO 15765 page.
How much does the ISO 15765 software cost and how it is licensed?
Please contact us for our price list and license details.
Does your ISO 15765 software protocol stack require an RTOS?

Which ISO 15765 messages does your protocol stack support?
Our ISO 15765 software supports all messages defined by ISO 15765-2 and ISO 15765-4.
Do we need ISO 15765-2 or ISO 15765-4?
ISO 15765-2 is used to support ISO 15765-3, ISO 14229, ISO 14230 networks while ISO 15765-4 is used for OBD2 networks.
