WebJan 22, 2024 · I wants to extract the bits from the CAN message (8 bytes). so, how to i extract bits from 8 bytes. In my opinion you should use some signals definitions from DBC or Arxml, and then act on Message::signal. But in case that you really want extract some bits from bytes use bitwise operations and masks. WebThe data length can be customized, but it is typically linked to the ID range (ID 0-31: 2 bytes, 32-47: 4 bytes, 48-63: 8 bytes). The data bytes contain the actual information being communicated in the form of LIN signals. The LIN signals are packed within the data bytes and may be e.g. just 1 bit long or multiple bytes. drew motors https://roschi.net
