Hi

 

I am trying to use the below to change the baud rate at run time and reset the CAN controller for activating the specfied baud, but the CANalyzer help does not tell how to configuer the various baud rate.

 

**************************************

long setBtr(long channel, byte btr0, byte btr1);

CAN channel

0 - Both controllers
1 -  channel 1
2 -  channel 2
 
BTR0 : Value of Bit Timing Register 0.
 
BTR1 : Value of Bit Timing Register 1.
 

Example
...

setBtr(0, 0x00, 0x3a); // 500 kBaud for 82C200

resetCan(); // aktivate

...
**************************************

Could some one share the details

 

Thanks in advance

 

Regards

Rajesh Maddukuri

Hello Rajesh,
 
these values depend on the concretely used CAN controller of your CAN adapter. For CANalyzer you can find this easily with the menu [ Configuration | Network hardware | CAN1 (or CAN2...)]. The entry CAN controller tells you which contoller isused. In the documentation of this controller (typically available in the datasheet/Internet) you will find out which values are appropriate.

You also can get some direct help in the CANalyzer menu [ Configuration | Network hardware | CAN1 (or CAN2...) | Setup]. There you find a mask, that allows to select a baudrate and see a table, which BTR values are required.

Best Regards / Mit freundlichen Gruessen
