WebDebugging via CAN Overview There are two tool interfaces that are using MCMCAN: › DAP over CAN Physical Layer (DXCPL) › DAP over CAN Messages (DXCM) The main use case for DXCPL is the analysis of field returns. DXCPL is using DAP telegrams wrapped in CAN messages. Once DXCPL is activated, the CAN node is disconnected from the CAN bus. WebMar 29, 2024 · TimeQuanta/BitTime : The number of TimeQuanta in a bit time: TQ/BT = SYNC + TSEG1 + TSEG2 = 1 + TSEG1 + TSEG2. SamplePoint : Position of the sample point in the bit time in percentage: SP = (SYNC + TSEG1) / TQ/BT * 100 %. BaudRate : Comes from the TimeQuantum, and the TQ/BT.
