Programmable Maritime Application System Based on Raspberry Pi Supports NMEA 2000 Functionality
NMEA 2000 is a marine networking standard created and administered by the National Marine Electronics Association (NMEA). The NMEA is an association of marine electronics manufacturers, dealers, and technicians. The NMEA 2000 standard describes a low-cost, moderate capacity, bi-directional, multi-transmitter, multi-receiver instrument network. Typical data on a network using this standard include: Position latitude and longitude. GPS status. Steering [...]
NMEA Online & Virtual Installer Trainings July 13-15, 2021
NMEA (National Marine Electronics Association) offers their installer certification classes to the marine electronics world this July 13-15. These are 6-8 hour online instructor-led installer certification training sessions. The delivery method for the training is GoToWebinar, where students view and listen to the live instructor and presentation, along with being able to ask questions to [...]
Controller Area Network (CAN Bus) Tutorial - Higher Layer Protocols
The following is an excerpt from A Comprehensible Controller Area Network by Wilfried Voss. Even though highly influential in automobiles and small applications, the CAN Bus technology alone is not suitable for machine automation since its communication between devices is limited to only 8 bytes. Consequently, higher layer protocols such as CANopen for machine control, DeviceNet for factory [...]
What is the Difference Between SAE J1939 and NMEA 2000?
After developing and programming multiple SAE J1939 devices over the years, I was curious to determine the difference between SAE J1939 and NMEA 2000. There are some valid reasons why I didn't consider an expansion into NMEA 2000, and they all have to do with the immense costs related to NMEA 2000 development. First of [...]
NMEA 2000 Powered Computer System With Raspberry Pi 4, NMEA 2000 HAT, Pre-Installed OpenPlotter And Signal K
Copperhill Technologies offers various NMEA 2000 compatible embedded systems, including HATs for the Raspberry Pi and the Arduino-compatible line of Teensy modules. The NMEA 2000 standard defines a low-cost, modest capacity, bi-directional, multi-transmitter, multi-receiver instrument network. The hardware layer utilizes the CAN (Controller Area Network) technology. Typical data on an NMEA 2000 network include: Position latitude and longitude GPS [...]

Controller Area Network (CAN Bus) And Higher-Layer Protocols CANopen, SAE J1939, NMEA 2000
For the longest time, the major misconception about Controller Area Network (CAN) was that it merely applies to automobiles. The truth is, CAN, since its introduction in 1986, proved to be a robust, versatile, and straightforward technology and, consequently, the CAN Bus technology found its way into all areas of applications where microprocessors need to [...]
