sub procedure CANSPISetOperationMode(dim mode as byte, dim WAIT
as byte)

Nothing.

Sets the CANSPI module to requested mode.

Parameters : 

- 

mode:

CANSPI module operation mode. Valid values: 

CANSPI_OP_MODE

con-

stants (see CANSPI constants). 
- 

WAIT:

CANSPI mode switching verification request. If 

WAIT = 0

, the call is non-

blocking. The sub function does not verify if the CANSPI module is switched to
requested mode or not. Caller must use 

CANSPIGetOperationMode

to verify correct

operation mode before performing mode specific operation. If 

WAIT != 0

, the call is

blocking – the sub function won’t “return” until the requested mode is set. 

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.

' set the CANSPI module into configuration mode (wait inside
CANSPISetOperationMode until this mode is set)
CANSPISetOperationMode(CANSPI_MODE_CONFIG, 0xFF)

sub function CANSPIGetOperationMode() as byte

Current operation mode.

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

CANSPI_OP_MODE

constants (see CANSPI constants) or device datasheet for

operation mode codes.
