1. Set the Baud rate
This function is used to initialize the baud rate of the CAN Bus system.
The available baud rates are listed as follows:
#define CAN_5KBPS 1
#define CAN_10KBPS 2
#define CAN_20KBPS 3
#define CAN_25KBPS 4
#define CAN_31K25BPS 5
#define CAN_33KBPS 6
#define CAN_40KBPS 7
#define CAN_50KBPS 8
#define CAN_80KBPS 9
#define CAN_83K3BPS 10
#define CAN_95KBPS 11
#define CAN_100KBPS 12
#define CAN_125KBPS 13
#define CAN_200KBPS 14
#define CAN_250KBPS 15
#define CAN_500KBPS 16
#define CAN_666kbps 17
#define CAN_1000KBPS 18
2. Set Receive Mask and Filter
There are
2
receive mask registers and
5
filter registers on the controller chip that
guarantee you get data from the target device. They are useful especially in a large
network consisting of numerous nodes.
