WebFeb 11, 2024 · The software PCAN-View for Windows® is a simple CAN monitor for viewing, transmitting, and recording CAN data traffic. Messages can be transmitted manually and periodically at a user-determined bit … WebBit Timing Control Registers The CAN Bit Timing Control (CNF) registers are the three registers that configure the CAN bit time. Figure 3 details the function of the CNF registers. By adjusting the length of the TQ (t TQ) and the number of TQs in each segment, both the nominal bit time and the sample point can easily be configured as desired.
