CAN FIFO driver blocks for the CAN-AC2-PCI with Philips SJA1000 CAN-Controller

5-15

Board — Defines which physically present board is used to send out the CAN

messages defined by this block instance. For more information about the

meaning of the board number see the Setup driver block described above. If one

board is present in the target system, select board number 1.

FIFO read depth — Defines the number of receive FIFO read attempts. Each

time the block gets executed it reads this fixed amount of events (CAN

messages) which lead to a deterministic time behavior independent of the

number of events currently stored in the receive FIFO. The Read depth (m)

defines at the same time the size of the matrix signal (m*6) leaving the first

output port. If no event is currently stored in the receive FIFO, the FIFO will

be read anyway, but the Event type will be reported as 0 (No new event).

Show status output port — Check this box to enable the Status output port.

If the box is unchecked (disabled) the block has one output port for the events.

If enabled, a second port is shown. The signal leaving that port is a vector of

type double with two elements.
