can any one plz tell me the average number of identifiers used in extended CAN which has 29 bit identifier..?? well definitely it depends on the application .. but on an average at least if any one can give me a percentage of identifiers left unused with some reference of article/book... that would be very helpful... if id=29 bit
posiible value =2^29 =536780912
if we want we can use all values but is there any application which requires shuch an extensive set of identifiers..? if yes .. what is it? if no .. what is the number of identifiers generally left unused?
