Higher-Layer Protocol Specifications for CAN XL

The new year will see the release of CAN XL and its implementation into new applications. Additionally, CAN in Automation (CiA) will provide higher-layer protocol (HLP) specifications for CAN XL.Since its introduction, CAN XL, the third generation CAN protocol, was developed to interact with TCP/IP networks. The CAN XL protocol provides a layer management service access point [...]

Application Note: Transmitting Analog Signals Using the SAE J1939 Protocol

This post is part of our series on Utilizing SAE J1939 as a Higher-Layer Protocol for Industrial Automation. In short, the application I had in mind was to read an analog signal per one SAE J1939 node and transmit the data to another J1939 node where it controls the blinking frequency of an LED. This project is based [...]

SAE J1939 Starter Kit and Network Simulator - New Hardware Variant Using the ESP32 Processor

Our SAE 1939 Starter Kit and Network Simulators allow experienced engineers and beginners to experiment with SAE J1939 data communication without connecting to a real-world J1939 network, i.e., a diesel engine. To establish a network, you need at least two nodes. That fact applies, especially to CAN/J1939 nodes. A single CAN Bus controller will shut [...]

Embedded CAN Bus, SAE J1939, NMEA 2000 Development With ESP32

Like many businesses in the CAN Bus marketplace, we have struggled with the global shortage of electronic components. For instance, our SAE J1939 gateways are equipped with NXP processors, mainly the LPC1754 and LPC1768. Unfortunately, both processors are currently unavailable, and they come with remarkably long delivery times that go well into next year. We [...]
