Hi John,

In can18xx8.h says :
enum CAN_RX_MSG_FLAGS
{
    CAN_RX_FILTER_BITS  = 0b00000111,   // Use this to access filter
                                        // bits
    CAN_RX_FILTER_1     = 0b00000000,
    CAN_RX_FILTER_2     = 0b00000001,
    CAN_RX_FILTER_3     = 0b00000010,
    CAN_RX_FILTER_4     = 0b00000011,
    CAN_RX_FILTER_5     = 0b00000100,
    CAN_RX_FILTER_6     = 0b00000101,

    CAN_RX_OVERFLOW     = 0b00001000,   // Set if Overflowed else
                                        // cleared

    CAN_RX_INVALID_MSG  = 0b00010000,   // Set if invalid else
                                        // cleared

    CAN_RX_XTD_FRAME    = 0b00100000,   // Set if XTD message else
                                        // cleared

    CAN_RX_RTR_FRAME    = 0b01000000,   // Set if RTR message else
                                        // cleared

    CAN_RX_DBL_BUFFERED = 0b10000000    // Set if this message was
                                        // hardware double-buffered
};


I found that and thought it would take care of it, but it doesnt!
Maybe the compiler doesnt find it or something.
Strange!

CAN_RX_MSG_FLAGS NewMessageFlags;    <<== AN738-EX18.c:24:Error: syntax

error

I haven't tried to build this, but glancing at the source,
CAN_RX_MSG_FLAGS is a tag, not a typedef, so I would think you'd need
enum CAN_RX_MSG_FLAGS NewMessageFlags;

Yes!

they are defined in the header. You can just use them... No need to define again!

if ( msg.flag & CAN_RX_MSG_FLAGS.CAN_RX_INVALID_MSG ) {
....

if ( msg.flag & CAN_RX_MSG_FLAGS.CAN_RX_XTD_FRAME ) {

......

etc
