There is no analytic formula for determining the optimum bit time in advance, so the calculator tries all of them. The closest integral baud rate prescaler is calculated for each value. The BRP and Tq/bit values are then used to calculate the actual sampling bit rate.

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. WebThe BxCAN supports three test modes: • In Silent mode, the BxCAN is able to receive valid frames, but it sends only recessive bits on the CAN bus and it cannot start a transmission. Silent mode can be used to analyze traffic on a CAN bus without affecting it by the transmission of dominant bits. • In Loop Back mode, the BxCAN treats its own
