FDCAN as Classic CAN in STM32G431KB for 500kbps

PJose.1

Hi,

Greetings

I have a board with STM32G431KB controller inside. i am trying to interface classic can into this controller to have bit rate of 500 kbps. However this particular controller has FDCAN and need to configure as classic can (BxCAN). I am in doubt of how to configure the bit timing parameter. I am using 170Mhz clock.

NominalPrescaler

NominalSyncJumpWidth

NominalTimeSeg1

NominalTimeSeg2

DataPrescaler

DataSyncJumpWidth

DataTimeSeg1

DataTimeSeg2

StdFiltersNbr

ExtFiltersNbr

i searched for several articles on how to configure the above shown parameters but could'nt find one good one. Please suggest one good method to assign values to above parameters so as to configure for 500 kbps bitrate as normal can.

Thanks in advance
