  • Can't get ik working yet. I have 2 CAN bus shields, each on an Arduino Uno. So i do not use it for my car, just regular CAN bus. I changed (soldered) the jumpers to use CAN. I have put a 120 Ohms termination resistor on each shield, between CAN Hi and CAN Lo. On one Arduino I use the Write sketch, on the other the Read sketch. Nothing is transmitted. Both sides say: "Can init OK' What else can I check?

    UPDATE: It works now. With a CAN bus tester I found that one shield was working, the other not. That's why they could not see each other. On the one that was not working a corrected a soldering error (I short circuited one of the CAN jumpers). Now they talk happily to each other...

No public wish lists :(
