OptoLyzer Studio and OptoLyzer MOCCA CL


CAN (Controller Area Network) has been an ISO standard for over 20 years and is still one of the most prominent automotive network technologies today. It can also be found in a large variety of application domains outside of automotive like industrial, building technology and medical. This video will explain CAN fundamentals and show a practical example that is analyzed with the help of development tools from K2L.

K2L at CAN FD Tech Days

CAN FD (CAN with flexible data rate) was introduced to the public by Bosch in March 2012. The first CAN FD Tech Day took place in Detroit (USA) in October 2012. Since then the one-day event has provided information about the CAN FD protocol and its applications in automotive and other industries. K2L used the opportunity to show their CAN FD demonstrators and products during the exhibtion.

Analyzing and Stimulating CAN with OptoLyzer® Studio and OptoLyzer® MOCCA CL

CAN (Controller Area Network) has become an ISO standard more than 20 years ago yet is still one of the most prominent automotive network technologies today and it will remain important for the foreseeable future. Today it can even be found in a large variety of application domains outside of automotive like industrial, building technology and medical!
Even though CAN has been stable for a long time, the tooling has not. In fact, with this webinar we would like to introduce you to the OptoLyzer® Studio software and the OptoLyzer® MOCCA CL hardware interface that in combination start a new era with respect of convenience, efficiency and modernity of CAN development tools.

Microchip Automotive Innovation Day - 24th September 2015

In April 2015 Microchip Technology and K2L proudly opened its new "Automotive Innovation Center", based at the international high-tech location, Technologie Park Karlsruhe (TPK).

We would like to invite you to the first Microchip Automotive Innovation Day where we will present you with trendsetting and innovative Automotive Technologies.

K2L Automotive Connectivity Demo


The Automotive Connectivity Demo was developed to a simulate an automotive distributed system based on CAN, LIN and MOST®. It shows the strength of the K2L solution Automotive Test System (ATS) working together with Microchip´s communication and connectivity products and technologies. The demo is operated entirely touchless, implementing Microchip’s GestIC® technology.

Free Webinar: High-Level Automotive Test and Simulation with ATS and C#/.NET, May 21

C# is one of the most popular programming languages today that is used in many different application domains. Modern, simple but yet expressive and therefore efficient - these are just some of the properties that are attributed to the language. Wouldn't it be awesome to develop tests and simulations for interconnected automotive devices and systems in C# and because of this boost efficiency?

K2L's Automotive Connectivity Demo @ HMI & Connectivity, Frankfurt, May 12-13

The Automotive Connectivity Demo was just recently designed to showcase a simulation of an automotive distributed system that is based on CAN, LIN and MOST. It shows the strength of the K2L solution Automotive Test System (ATS) together with some mainstream Microchip products and technologies, like GestIC®.
