How to use the library
4. TX_MSGx_STDID - The standard id part for the MSGx to be transmitted, where x = transmit
message number.
5. TX_MSGx_EXTID - The extended id part for the MSGx to be transmitted, where x =
transmit message number.
6. TX_MSGx_DLC - The length for the MSGx to be transmitted, where x = transmit message
number. The maximum length that can be defined is 8.
7. RX_MSGx_DLC - The length for the MSGx to be received, where x = receive message
number. The maximum length that can be defined is 8.
8. REG_INITx_VALUE - The register initialization value for the CAN controller register, where
REG - register name, x = init structure number.
The following are the parameters that must be configured in the file user.c -
1. MSGx_Tx_Buffer - This declares the buffer for the MSGx to be transmitted. The length of
the buffer is the same as defined by the parameter TX_MSGx_DLC in the file user.h. The
number of such buffers to be declared is the same as defined by the parameter
NO_OF_TX_HANDLES in the file user.h.
2. tx_stdid[ ] - This table stores the standard id value/s for the message/s to be transmitted.
The length of the table is the same as defined by the parameter NO_OF_TX_HANDLES and
the value/s stored inside is/are the same as defined by the parameter TX_MSGx_STDID in
the file user.h. If the message to be transmitted is Extended then above has to logical-ORed
with the EXT_ID_MASK(IDE bit), EXID17 & EXID16 bit values. As a result, the values stored
inside the table are in the same format as of MIDR0 & MIDR1 registers.
3. tx_extid[ ] - This table stores the extended id value/s for the message/s to be transmitted.
The length of the table is the same as defined by the parameter NO_OF_TX_HANDLES and
the value/s stored inside the table is/are the same as defined by the parameter
TX_MSGx_EXTID in the file user.h. It stores the values into the same format as of MIDR2 &
MIDR3 registers.
4. tx_dlc[ ] - This table stores the length for the message/s to be transmitted. The length of the
table is the same as defined by the parameter NO_OF_TX_HANDLES and the value/s stored
inside the table is/are the same as defined by the parameter TX_MSGx_DLC in the file user.h.
5. tx_data_ptr[ ] - This pointer table stores the address of transmit buffer/s (MSGx_Tx_buffer).
The length of the table is the same as defined by the parameter NO_OF_TX_HANDLES in the
file user.h.
6. MSGx_Rx_Buffer - This declares the buffer for the MSGx to be received. The length of the
buffer is the same as defined by the parameter RX_MSGx_DLC in the file user.h. Number of
such buffers to be declared is the same as defined by the parameter NO_OF_RX_HANDLES
in the file user.h.
