dim CANSPI_CONFIG_FLAGS as byte)

Description Configures message filter. The parameter 

value

 is bit-adjusted to the appropriate filter registers.

Parameters - 

CANSPI_FILTER

:  CAN  module  filter  number.  Valid  values: 

CANSPI_FILTER

  constants.  See 

CANSPI_FILTER constants. 

- 

val

: filter register value. This value is bit-adjusted to appropriate filter registers 

- 

CANSPI_CONFIG_FLAGS

: selects type of message to filter. Valid values:

The  CANSPI  module  must  be  in  Config  mode,  otherwise  the  function  will  be  ignored.  See 

CANSPISetOperationMode.

The CANSPI routines are supported only by MCUs with the SPI module.

MCU has to be properly connected to mikroElektronika’s CANSPI Extra Board or similar hardware. 

See connection example at the bottom of this page.
