CANSetBaudRate(char SJW, char BRP, char PHSEG1, char PHSEG2,
char
PROPSEG, char CAN_CONFIG_FLAGS);
Description
Sets CAN baud rate. Due to complexity of CAN protocol, you cannot simply force a bps
value. Instead, use this function when CAN is in Config mode. Refer to datasheet for
details.
Parameters:
SJW
as defined in 18XXX8 datasheet (1–4)
BRP
as defined in 18XXX8 datasheet (1–64)
PHSEG1
as defined in 18XXX8 datasheet (1–8)
PHSEG2
as defined in 18XXX8 datasheet (1–8)
PROPSEG
as defined in 18XXX8 datasheet (1–8)
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;
