This node will synchronize at the edge from the FDF bit WebThe bit timing calculations in can-utils are certainly wrong, and after a quick look at the ones that make up the kernel is appears that they are not quite right as well. TQ = 2*(BRP-1)/Fosc Looking at the kernel: can/dev.c defines best brp as: 182 >---v64 = (u64)best_brp * 1000000000UL; WebCAN network has its own clock generator, usually a quartz oscillator. The timing parameter of the bit time (i.e. the reciprocal of the bit rate) can be configured individually for each CAN node, cre-ating a common bit rate even though the CAN nodes’ oscillator periods (fosc) may be different. daily stipend government
