Hi,
I am working on LPC2364 processor for the first time I have to configure CAN controller.
I am seeing there are many website which provide timing calculator but no one discuss about how to achive those register value.

I am using 12Mhz freq and want to achive 125K baud rate communication
I want to understand what should be my BRP value to achive 125K and how to select Seg1 and Seg2 value for the rgisters?
How to calculate BRP value?

Any help would be appriciated...

Thanks,

Hi,

See this thread on the LPC11Cxx:
http://www.lpcware.com/content/forum/lpc11c-can-baudrate-configuration

The configuration for the LPC2364 is similar.

Wouter

I am trying to use RL CAN driver, and it looks like it doesn't configure BTR register properly. Does it work? Can I just add RL files and CAN port starts working...

Hello,
I am using LPC1769 for CAN implementation
XTAL freq is 12 MHZ
Pclk=16Mhz
Cclk=64 MHZ
I want bitrate of 125kbps..can you please suggest appropraite setting for bus timings or any document from where i can refer from for lpc1769 CAN bus settings as i searched on the net but didn find any sample codes also..
