6.2.4.3 DATA TYPES
The following are the data types used by the driver-
canuint8
canuint16
There are some data types referenced while calling driver function -
CanInitHandle
figured initialization modes).
CanTransmitHandle 8-bit unsigned integer (application-specific, depends on the number of
transmit objects).
tCanMsgObject typedef volatile struct
T h i s i s a t r a n s m i t m e s s a g e s t r u c t u r e r e f e r e n c e d f o r t h e C A N d r i v e r s e r v i c e
CanMsgTransmit().
6.2.4.4 MEMORY USAGE
Constants
This includes the initialization values inside the Init Structure for the CAN controller registers,
transmit message information(tx_id, tx_dlc) inside the transmit structure, and receive mes-
sage information(rx_dlc). These are stored in ROM.
Global Variables
These include the transmit & receive buffers, confirmation & indication flags, pointers to the Tx
& Rx buffers, and receive message id’s(rx_id).
6.2.4.5 PARAMETER CONFIGURATION
There are certain parameters that you have to configure depending on the application. These
parameters are configured inside the files user.c & user.h.
The following are the parameters that must be configured in the file user.h -
1. NO_OF_TX_HANDLES - This parameter defines the number of messages to be trans-
mitted by the application.
2. NO_OF_RX_HANDLES- The number of messages to be received by the application which
depends on the number of messages configured in the filter registers.
3. NO_OF_INIT_HANDLES- The number of initialization structures required in an application.
By default, its value is set to 1.
