procedure CANSPISetOperationMode(mode: byte; WAIT: byte);

Nothing.

Sets the CANSPI module to requested mode.

Parameters : 

- 

mode

: CANSPI module operation mode. Valid values: 

CANSPI_OP_MODE

constants (see CANSPI constants). 

- 

WAIT

: CANSPI mode switching verification request. If 

WAIT = 0

, the call is non

blocking. The function does not verify if the CANSPI module is switched to request-
ed mode or not. Caller must use 

CANSPIGetOperationMode

to verify correct oper-  

tion mode before performing mode specific operation. If 

WAIT != 0

, the call is  

blocking – the 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);
