Hello I am using The UAVCAN to establish communication between 3 pixhawks. I have created 36 custom data type to be able to carry the data among the pixhawks but when I try to send the messages I get some HW and IO errors on CAN1 statues and a lot of HW and IO errors on CAN2 status when I decrease the number of messages sent on the bus I get zero HW and IO errors on CAN1 status but still a lot of HW and IO errors on CAN2 status.
so my question is that a hardware problem because I am only using 1 I2C cable for the communication between the pixhawks and I don’t know if I must terminate it with 120 ohm or it is already terminated
P.S I am using Pixhawk FMUv3 and it has only one CAN communication socket.
Thanks In advance
