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 [...]
Arduino-Due-Based SAE J1939 Programming Kit - Quick Start Reference
Unleash the power of the Arduino Due with ARM Cortex-M3 processor to develop and test your SAE J1939 application, may it be an SAE J1939 to USB protocol converter, an SAE J1939 Bridge, an SAE J1939 data monitor, and many more. The SAE J1939 Programming Kit comes with many programming samples, including a full-blown SAE J1939 [...]
A Simple SAE J1939 to USB Gateway with the Arduino Uno, Mega 2560, Due, Teensy, ESP32
The following is an excerpt from SAE J1939 ECU Programming & Vehicle Bus Simulation with Arduino by Wilfried VossI deem it necessary to clarify the definition of “SAE J1939 to USB Gateway” because there are several variants of gateway applications.If you browse through the Internet in search for SAE J1939 gateways, you will primarily find CAN [...]
CAN Bus And SAE J1939 Prototyping With The Arduino Due ARM Cortex M3 Processor
Whenever it comes to building rapid prototypes for new CAN Bus or SAE J1939 applications, my first choice is regularly the Arduino Due, a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.In general, the Arduino platform couples an easy-to-use programming environment (IDE) with a vast number of hardware extensions (shields). While I do appreciate programming [...]
CAN Bus Prototyping With Arduino Uno - Prototyping Hardware
This post is part of a series about Controller Area Network (CAN Bus) Prototyping With the Arduino Uno. As I had mentioned earlier, it is assumed that you have some basic knowledge of the Arduino, Arduino Sketches, and Arduino Shields. I will nevertheless take the opportunity of mentioning the prototyping hardware and its variants. It is important to know that the [...]
Arduino Due - Programming And Debugging Using JTAG ICE And Atmel Studio
Atmel’s SAM3X series MCUs are great for users who want to move further from the world of 8bit/16bit microcontrollers to 32bit ARM Cortex core MCUs. One of the most famous device in this series is SAM3X8E, Atmel’s Smart ARM microcontroller. The development platform of choice for getting started with the SAM3X8E is the Arduino Due board. The SAM3X8E [...]
Arduino Due Firmware Flaw: Problem With Using The USB Programming Port At 230400 Baud And Beyond
One of the improvements that came with the Arduino IDE's updates was an increased baud rate for the Serial Monitor. Well, there are many time-sensitive applications that will benefit from the speed gain, specifically when using one of the fastest Arduinos around, the Arduino Due with its ARM Cortex M3 processor. However, when you set the Serial [...]
ARM Cortex Processors – UART Programming Problem At Baud Rates Higher Than 115200
To say it upfront, I cannot confirm with 100% certainty that all ARM Cortex microcontrollers are affected by the UART programming problem as described in the following, but there are indications that make my assumption very probable. The outcome depends primarily on thorough testing of serial communication applications, but there is evidence to the contrary [...]
Programmable, Arduino-Due-Based USB Gateway With Two CAN Bus Ports
As part of our business strategy of providing prototyping solutions for the CAN Bus (including SAE J1939, ISOBUS, NMEA 2000) we have decided to focus more on the Arduino platform, specifically the Arduino Due. The Due, while providing the power of an ARM Cortex M3 processor, comes with two CAN Bus ports per default, however, lacking the [...]
