Hi,

I worked with your test program and it is working fine

Now I modified your code to work like a chatting system b/w two PC's as shown below

PC-1 <-----> NODE1 <-----> NODE ...

Thanks a lot

I got some ack b/w the two nodes

With some other information i will get back to you

Thanks and regards

Hi,

Thank you.

With the above modifications I got the loopback mode perfectly.

Now I am trying to transmit the data b/w each other.

I will be thankful if you provide any sample code to tx- ...

Sry,

I connected PIC to MCP2515 only. By mistake I entered MCP2551 instead of MCP2515.

With the above program I am not getting the CAN Initializing properly.

It is giving the output as follo ...

After a long time again I started to fight with the CAN.

My board is not answering properly for the loopback mode.

Is it needs any pullups for the IO lines b/w the PIC and the MCP2551?

Thanks

Hi,

I am designing the two CAN nodes with PIC16F877A and MCP2515.

I am using the CCS C libraries:

#include <can-mcp251x.h>
#include <can-mcp251x.c>

But I am not getting the p ...

Thanks,

I got the 33khz with the ASM. How can I include the ASM routine in the CCS C ?

The following is the code that i have written. I have simulated this by using the PROTEUS. But it is giving 6kHz. I tested with oscilloscope also. The result is same.

#include <16F676.h>

Thanks,

Your code is working properly, but my application includes some
other tasks. So here I want to use the Timer0 interrupt for this.

I want to calculate the Timer0 loadable value to ...
