CANSPIGetOperationMode

CANSPIInit

Prototype

sub function CANSPIGetOperationMode() as byte

Description The function returns current operation mode of the CANSPI module. Check CANSPI_OP_MODE

constants or device datasheet for operation mode codes.

Parameters None.
Returns

Current operation mode.

Requires

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.

Example

‘ check whether the CANSPI module is in Normal mode and if it is do

something.

if (CANSPIGetOperationMode() = _CANSPI_MODE_NORMAL) then

...

end if

Notes

None.

Prototype

sub procedure CANSPIInit(dim SJW, BRP, PHSEG1, PHSEG2, PROPSEG, CANSPI_

CONFIG_FLAGS as char)

Description Initializes the CANSPI module.

Stand-Alone CAN controller in the CANSPI module is set to:

- Disable CAN capture

- Continue CAN operation in Idle mode

- Do not abort pending transmissions

- Fcan clock: 4*Tcy (Fosc)

- Baud rate is set according to given parameters

- CAN mode: Normal

- Filter and mask registers IDs are set to zero

- Filter and mask message frame type is set according to CANSPI_CONFIG_FLAGS value

SAM

SEG2PHTS

WAKFIL

and

DBEN

bits are set according to CANSPI_CONFIG_FLAGS value.
