Hello, I just got couple of Neo Full boards and these SN65HVD230 units. I would like to capture in this thread about various steps and explanation from some of the members here who has experience with CAN for some of us that are starting with it. Please add any steps you think are important or anything someone else overlooked I have two of such boards installed with minimal image and configured to can. How to configure can on Neo please check out great post http://www.udoo.org/forum/threads/enabling-and-verifying-flexcan-support.3617/ So my understanding is that on Neo board has two CANs operation at 3.3V http://www.udoo.org/docs-neo/Hardware_&_Accessories/CAN_bus.html http://www.udoo.org/docs-neo/img/gionji/DOCS_external_pinout.PNG So this brings two general questions What is the best place/script to place to run on boot up ip link set can0 type can bitrate 250000 ip link set can1 type can bitrate 250000 Answer: edit /etc/networking/interfaces and add auto can0 iface can0 inet manual #pre-up ip link set $IFACE type can bitrate 250000 listen-only off pre-up /ip link set $IFACE type can bitrate 250000 triple-sampling on up /sbin/ifconfig $IFACE up down /sbin/ifconfig $IFACE dow I got this unit that I found was recommended by some users. http://www.waveshare.com/wiki/SN65HVD230_CAN_Board#Support To connect this unit to Neo you connect SN65HVD230 Udoo Neo (Can0 is Pin 40 and 41, Can1 is Pin 42 and 43) CANTX Pin to Pin 41 (CAN1_TX) J7 // This is can0 CANRX Pin to Pin 40 (CAN1_RX) J7 // This is can0 GND to Pin GND 3.3V to 3.3V SN65HVD230 has already bulletin 120 resistor Now connect CAN_H to CAN_H and CAN_L and CAN_L between two SN65HVD230 And you are set to go
