Free Online Book: SAE J1939 ECU Programming And Vehicle Bus Simulation With Arduino Uno, Mega 2560, And Due
The implementation of an SAE J1939 protocol stack was (and in many cases still is) out of financial reach for many engineers. The software (i.e. the source code) is either grossly overpriced or comes with hefty royalties (object code, libraries), meaning you have to pay for each copy. At least in the case of the Arduino hardware, this is going to change, and the ARD1939 protocol stack project is available as a free download.
