You are right there is no shortcut to good engineering.
I will go through the documents first and then conduct experiments
on it... I will get back to you with the result..
Thanks once again

Hi,
The acceptance filter/mask system allows you to confine reception to no
identifier, all identifiers or anything in between. You need to spend
time reading the docs and then conduct experiments to prove out your
understanding. There are no shortcuts to good engineering.

Hi rob,
Thanks for the info. But my question is using Acceptance
filter regisgters how many maximum messages i can have for standard
frame?

Hi,
I think there are plenty of appnotes floating around for setting up
acceptance filters/mask (my own code has too many dependencies to be
readily useful) but one feature little touched on is the usefulness of
the IDHIT bits inside the CANIDAC register. If you set one filter for
0x100 and another for 0x101 you can simply direct rx traffic by
inspecting these 3 bits.

Hi all...
I have two messages with ID 0x100 and 0x101. What all i need
to set in Acceptance filter register and acceptance mask register?
Can anyone explain with an example?
I am using CAN in standard forat(11 bit identifier) and 4 16
bit filter mode.
