WebAug 9, 2024 · 2. To implement the initial value for the CRC you just have to set crc in the beginning to what you want to have. So either. uint8_t crc [8] = {1,1,1,1, 1,1,1,1}; or. memset (crc,1,8); But you have a flaw in your logic and that is the reason why you do not get the right values (even without the init value).

WebThe SAE J1850 protocol is based on a bus-level topology wherein the bus is a masterless peer-to-peer (P2P) protocol. Just like the CAN, messages are broadcast in the sense that whatever messages have to be sent are sent in the form of frames to all the nodes, irrespective of the desired destination. This protocol supports two modes.
