Softing CAN-AC2-104 with Philips SJA1000 FIFO Read RCV Level

Softing CAN-AC2-104 with Philips SJA1000 FIFO Read RCV Level block


Simulink® Real-Time™ Library for CAN


The FIFO Read RCV Level driver block reads the current number of CAN messages stored in the receive FIFO. The receive FIFO can store up to 127 events (messages). If it is full and a FIFO Read driver block does not attempt to read the stored events, the driver ignores new incoming events. Increments to the lost message counter mark the lost messages. You can use this driver block to check for this condition and perform an error action. For example, you can stop the execution or reset the receive FIFO.

The block has a single output port of type double, returning a scalar value containing the current receive FIFO level (number of messages to be processed).

Block Parameters


Defines the board to access to read the current receive FIFO level. For more information about the meaning of the board number, see the Setup driver block. If just one board is present in the target system, select board number 1.

Sample time

Defines the sample time at which the FIFO Read RCV Level driver block is executed during a real-time application run.
