Content originally posted in LPCWare by rmilne on Thu Mar 28 08:42:21 MST 2013 I have no issue getting the LPCOpen periph_ccan demo to work but I cannot figure out how to set the filtering to allow any extended message to appear in a message buffer. I see the RXOK bit getting set in the status register but the intid is always 0. The documentation (UM10503.pdf) is poor and the code examples are for single address only (no address range example). Can someone please direct me to a project or document that clearly illustrates how to setup the peripheral to receive a range of CAN extended ids?
