Can bus baud rate setting of stm32cubemx

Doing in recently CAN Related issues , The transmission rate is from 125Kbps To 1Mbps Unequal , Due to the use STM32CubeMX As a code generation platform , So the calculation CAN Baud rate needs to be calculated by yourself , But I can't remember it again , Simply calculate it directly once and write it down ！

CAN The baud rate of depends on the clock tree APB1 Clock The frequency of , The main parameters are ：

• The prescaled coefficients
• Time slice 1
• Time slice 2
• SWJ

following CAN The parameter is APB1 Clock by 36MHz Calculated ：

Baud rate bps	The prescaled coefficients	Time slice 1	Time slice 2	SWJ
100K	60	3	2	1
125K	48	3	2	1
200K	30	3	2	1
250K	24	3	2	1
400K	10	5	3	1
500K	12	3	2	1
800K	5	5	3	1
1M	6	3	2	1

Encounter the contents in the table if STM32CubeMX If it is not allowed, set it casually , Generate the code in CAN Can be modified in the initialization function of ！
