AM2432: How to set parameter for 500k baud-rate of standard frame format CAN

ShengYi Lin

Part Number: AM2432

Hi Sir

I want to set 500k baud-rate of standard frame format CAN.Could you show me how to do it.

I can set 1M baud-rate of standard frame format CAN
Setting below bitTime parameter could get 1M baud-rate of standard frame format CAN .

Changing nomRatePrescalar from 0x03 to 0x07 for 500k bit-rate of standard frame format CAN as below picture but baud mismatch.

Could you show 500 kbps's parameter for baud-rate of standard frame format CAN to me.

Hi, Sheng. Can you please try this values for 500k Baud:

We've this view for timing parameters calculation in syscfg, can try values here and save the configuration before closing. This will update timing parameters.

Hi Sir

It is useful.

Recommended the sampling should be set between 85% to 90%.
