I'm using extended identifiers fine with code based on the 
LPC_CANAll.zip example. The FullCAN does not work for extended 
identifiers.

I found only one problem in LPC_CANAll. The code did not clear 
pending errors on initialisation

    ....
  pSFR = (unsigned int *) &C1MOD + offset; // Select Mode register
  *pSFR = 1; // Go into Reset mode

  // Start of added code
  pSFR = (unsigned int *) &C1CMR + offset; // Select command register
  *pSFR = 0x0E; // Clear receive buffer, data overrun, abort tx

   // End of added code

  pSFR = (unsigned int *) &C1IER + offset; // Select Interrupt Enable 
Register
  *pSFR = 0;// Disable All Interrupts
....
