Hello,
My name is Leo, I work with a uController LPC2368 and I'm in a CAN bus project.
I recently bought on the Internet a CAN J1939 Simulator(Dafulai Electronics), but I can't send a message to the simulator successfully. I configured the uC to generate an interrupt every time that it sends or receives a message, but this interrupt is NEVER generated.
By the way, I'm able to make a communication in self test mode.
Reading about the CAN bus, I realize that it uses CSMA/CD technique. My doubt is, does the uController do by it self the verification on the bus before the transmission, or should I do this by software?
Waiting for a help! Thank you!
