Advanced IoT Programming Using The Raspberry Pi 4 And Python 3

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, made it very attractive for Rapid Application Development. It is used as a scripting or glue language to connect existing components. Python's simple, easy-to-learn syntax emphasizes readability and therefore reduces the cost of [...]

SAE J1939 250k/500k Baudrate Converter Using Arduino Due With Dual CAN Bus Port

In the past months, customers have approached me regarding a CAN Bus baud rate converter for SAE J1939 networks. The original SAE J1939 Standards Collection was limited to a baud rate of 250k, basically to keep things simple and reliable. I don't know what triggered the decision to add the additional 500k baud rate. From [...]

ESP32 Project: CAN Bus, SAE J1939, NMEA2000 Converter With IoT Functionality

It was just a few weeks ago that I received some bad news. Due to the worldwide shortage of electronic components, the NXP LPC1754 processor we use for our SAE J1939 ECU Simulator with USB Port will not be available for several months, maybe even well into 2022. Consequently, it was time to rethink the design, and [...]
