Under Development: SAE J1708 to UART Breakout Board For Embedded Systems
SAE J1708 is a standard used for serial communications between ECUs on a heavy duty vehicle and also between a computer and the vehicle. With respect to Open System Interconnection model (OSI), J1708 defines the physical layer. Common higher layer protocols that operate on top of J1708 are SAE J1587 and SAE J1922. The protocol [...]
Monitoring SAE J1708/J1587 Data Traffic Using The Arduino Mega2560 Or Arduino Due
First of all, let me point out that this post is merely about monitoring SAE J1708/J1587 data traffic, i.e. the mere reading of data frames. SAE J1708, the hardware layer, is based on RS485, however, with a small hardware modification that allows message collision detection and prevention. In the following, I am using an RS485 [...]
