Four Channel CAN Bus to USB Gateway Using The Arduino Due

In the past, I frequently received inquiries regarding the availability of a four-channel CAN Bus gateway. Such devices exist in the marketplace; however, they are usually costly, and, after all, they don't support easy customization or programming. While we at Copperhill Technologies have the ability to create such a gateway, this is primarily a matter [...]

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 [...]

SAE J1939 vs. CAN Bus - What's the Difference?

To say it upfront, the difference between SAE J1939 and CAN Bus (Classical CAN and CAN FD) has all to do with so-called "Higher Later Protocols (HLP)," and SAE J1939 is one of them. I have written a post about HLPs (see: Guide to SAE J1939 - CAN Bus Higher Layer Protocols), but I would like [...]
