Raw CAN Rx Buffer Overflow - Intrepidcs API
Main

Each CAN Controller in neoVI has an Rx FIFO buffer to read CAN messages. If rx buffer is full when a new CAN message arrives a CAN Rx Buffer overflow occurs. This normally will not happen but could result if the neoVI microcontroller does not reads the buffer fast enough.
