The sample-point is the percentage of the nominal bit time at which the CAN controller will sample the state of the bus. This is usually later in the bit time to ensure the signal has stabilised. ![[can-sample-point.svg]] For most systems a sample-point of 87.5% (i.e. 7/8ths) is used, however some standards like DroneCAN allow as little as 75% to be used. # On Linux # iproute2 ```shell # Configure a sample point of 87.5 on interface can0 ip link set can0 type can sample-point 0.875 ``` ## networkd Config ```ini [CAN] SamplePoint=87.5% ```
