Re: CAN message with DLC > 8 and PIC18

Hello

Very interesting information. I dully thought that having seen DLC of 10 or
12 meant a physical frame with that length.

A have no experience with multipacket on PIC microcontroller but i will
keep digging to see if there is a protocol stack provider for such
technology

Thank you!!
