CANInitializemikroC - C Compiler for Microchip PIC microcontrollers
Prototype | void CANInitialize(char SJW, char BRP, char PHSEG1, char PHSEG2, | ||
| char PROPSEG, char CAN_CONFIG_FLAGS); |
| |
|
| ||
Description | Initializes CAN. All pending transmissions are aborted. Sets all mask registers to 0 to | ||
| allow all messages. |
|
|
| Filter registers are set according to flag value: |
| |
| if (CAN_CONFIG_FLAGS & CAN_CONFIG_VALID_XTD_MSG != 0) | ||
| // Set all filters to XTD_MSG |
|
|
| else if (config & CONFIG_VALID_STD_MSG != 0) | ||
| // Set all filters to STD_MSG |
|
|
| else |
|
|
| // Set half the filters to STD, and the rest to XTD_MSG | ||
| Parameters: |
|
|
| SJW as defined in 18XXX8 datasheet |
|
|
| BRP as defined in 18XXX8 datasheet |
|
|
| PHSEG1 as defined in 18XXX8 datasheet |
| |
| PHSEG2 as defined in 18XXX8 datasheet |
| |
| PROPSEG as defined in 18XXX8 datasheet |
| |
| CAN_CONFIG_FLAGS is formed from predefined constants (see CAN constants). | ||
|
| ||
Requires | CAN must be in Config mode; otherwise the function will be ignored. | ||

Example | init = CAN_CONFIG_SAMPLE_THRICE | & |
|
| CAN_CONFIG_PHSEG2_PRG_ON & |
| |
| CAN_CONFIG_STD_MSG | & |
|
| CAN_CONFIG_DBL_BUFFER_ON & |
| |
| CAN_CONFIG_VALID_XTD_MSG & |
| |
| CAN_CONFIG_LINE_FILTER_OFF; |
| |
| ... |
|
|
| CANInitialize(1, 1, 3, 3, 1, init); | // initialize CAN | |
