AVR CAN Bus Project – Status Update 1

I got the circuit wired up yesterday: The 6-pin jumper on the left lets me select one of the 3 CAN buses on the Nissan Leaf accessible via the OBD-II connector. I hacked up some code quickly, and was pleasantly surprised that it actually worked! Woohoo! The part I thought was going to be most […]

AVR CAN Bus Project – Step 2: Programming Low Fuse

One of the basic functions that the CAN Bus project needs is to be able to communicate with a PC via a serial port.  For modern PC’s the most straightforward way is to connect the AT90CAN128 header board to the host via a Serial->USB converter.  The most common type is the ubiquitous FTDI Cable, which […]

AVR CAN Bus Project – Step 1: Programming AT90CAN128 with Arduino
