CCS CAN Driver
PostPosted: Mon May 10, 2004 1:54 pm     Reply with quote
In the CCS CAN driver it puts transmit data into buffer 0. If buffer 0 is faull, it then puts it into buffer 1. If buffer 1 is full it then puts it into buffer 2. If all the buffers are full it then exits with an error.

In the Microchip specs it says that it sends data starting with buffer 2, then buffer 1 and then sends buffer 0 last.

So, should the CCS driver be reversed?

It would be best if it started with 2 then 1 then 0. And only fill 1 if 0 is empty. Only fill 2 if 1 and 0 are empty. That would insure the buffers are sent FIFO.

Thats "my take on it" not to be confused with "the best solution".

Maybe an option for FIFO or LIFO would be best.
