CAN FIFO Demonstrations

xPC Target CAN FIFO Demonstrations for CAN-AC2-PCI and CAN-AC2-104 Boards

The xPC Target product contains the following demos that illustrate the use of the Softing CAN FIFO blocks. Some models use CAN_MESSAGE data types, some use double data types. Models that use double data types are considered legacy demos. Each demo requires a loopback cable connected between the two ports on the board. The demos send messages on port 1 and receive messages on port 2.

These models have the following naming conventions:

• Model names appended with s — Output is a vector of CAN_MESSAGE data with length equal to the value of the FIFO read depth parameter. This length is also the maximum number of messages that the block returns. The second output port returns the number of messages that are present in the output.

• Model names appended with sf — Output contains one CAN_MESSAGE message at a time. The block calls the function-call output between 0 and FIFO read depth number of times, depending on how many messages are in the FIFO.

CAN I/O FIFO Mode - Simple Use Case — CAN_MESSAGE data type CAN I/O FIFO Mode — Simple Use Case — Double data type	CAN I/O FIFO Mode - Simple Use Case — CAN_MESSAGE data type CAN I/O FIFO Mode - Simple Use Case — Double data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards and illustrates basic functionality of the boards.
CAN I/O FIFO Mode - Simple Use Case (with CAN_MESSAGE and Function Call Output) — CAN_MESSAGE data type	CAN I/O FIFO Mode - Simple Use Case (with CAN_MESSAGE and Function-Call Output) — CAN_MESSAGE data type	Softing CAN-AC2-PCI board and illustrates CAN I/O communication using the First In First Out (FIFO) mode. The FIFO Read block uses a function-call output format.
CAN I/O FIFO Mode - The "No New Event" Message — Double data type	CAN I/O FIFO Mode - The "No New Event" Message — Double data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards and illustrates the condition and detection of the No new event message.
CAN I/O FIFO Mode - Dynamic Message Generation — CAN_MESSAGE data type CAN I/O FIFO Mode - Dynamic Message Generation — Double data type	CAN I/O FIFO Mode - Dynamic Message Generation — CAN_MESSAGE data type CAN I/O FIFO Mode - Dynamic Message Generation — Double data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards and illustrates how CAN messages can be dynamically constructed at run-time.
CAN I/O FIFO Mode - Stopping on FIFO Overflow — CAN_MESSAGE data type CAN I/O FIFO Mode - Stopping on FIFO Overflow — Double data type	CAN I/O FIFO Mode - Stopping on FIFO Overflow — CAN_MESSAGE data type CAN I/O FIFO Mode - Stopping on FIFO Overflow — Double data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards. For the case where data is being received faster than it is being processed, these demos illustrate how to stop execution of the model after detecting a receive FIFO overflow.
CAN I/O FIFO Mode - Resetting before FIFO Overflow — CAN_MESSAGE data type CAN I/O FIFO Mode - Resetting before FIFO Overflow — Double data type	CAN I/O FIFO Mode - Resetting before FIFO Overflow — CAN_MESSAGE data type CAN I/O FIFO Mode - Resetting before FIFO Overflow — Double data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards. For the case where data is being received faster than it is being processed, these demos illustrate how to reset the receive FIFO before it overflows.
CAN I/O FIFO Mode - Acceptance Filters — CAN_MESSAGE data type CAN I/O FIFO Mode - Acceptance Filters — Double data type	CAN I/O FIFO Mode - Acceptance Filters — CAN_MESSAGE data type CAN I/O FIFO Mode - Acceptance Filters — Double data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards and illustrates how to use acceptance filters. The objective is to filter any CAN messages with an identifier larger than 127.
CAN I/O FIFO Mode - Loading Messages from CANdb DBC Files — CAN_MESSAGE data type	CAN I/O FIFO Mode - Loading Messages from CANdb DBC Files — CAN_MESSAGE data type	Softing CAN-AC2-PCI and CAN-AC2-104 boards. The demo loads message and signal definitions from a CANdb DBC database file. This demo assumes that the CANdb file, demoData.dbc, resides in the xpcdemos folder.
