Macros
CAN bus speed.
Determines the speed for the can bus. This options determines the speed for the CAN bus. For autobauding use the definition CAN_AUTOBAUD or 0.
#define	CAN_BAUDRATE   250
CAN transciever enable.
CAN transciever hardware enable control. If your CAN transciever has enable/disable functionality that can be controlled by GPIO, use these defines to set the correct port and IO for that. This will enable the transciever only after init has been completed succesfully. If you use autobauding, the transciever will be enable immediately after startup.
#define	CANRS_PORT   PORTD
#define	CANRS_DDR   DDRD
#define	CANRS_PIN   PIND0
CAN chip hardware config.
Pin definitions for the on chip can hardware. Set these per processor. Default is AtMega64C1 and equivalent.
#define	CAN_PORT_IN   PINC
#define	CAN_PORT_DIR   DDRC
#define	CAN_PORT_OUT   PORTC
#define	CAN_INPUT_PIN   2
#define	CAN_OUTPUT_PIN   3
CAN chip MOB config.
Message object buffer definitions. Set these per processor. Default is AtMega64C1 and equivalent. The number of TX buffers is determined by subtracting the amount of RX buffers from the total amount.
#define	NB_MOB   6
#define	NB_RX_MOB   4
Can based debug message filtering.
Filter CAN based debug messages (ID 0x80) Keep this define to use a software filter to filter out CAN debug messages used by the full protocol. Delete this in your own implementation or if you wish to receive all messages.
Version information for bootloader.
Bootloader version information. Change these to modify your bootloader version number that is reported in the response message from the node when a session open is requested. Note Remember to update the documentation version also when incrementing this.
#define	BL_VERSION_MAJOR   0
#define	BL_VERSION_MINOR   1
#define	BL_VERSION_BUILD   0
Node type definition (node identification byte).
Change this to identify the module type you are about to flash. Can be any uint8_t value. This will also be reported in the response message from the node. Todo: Enum?
#define	NODETYPEDEF   0x00
Calculated number of flash pages.
Calculated number of flash pages calculated by dividing the flash end by the amount of bytes in a page. #include <avr/io.h> Note Processor defintion files should make this work on all Atmega devices.
#define	SPM_MAXPAGES   (FLASHEND / SPM_PAGESIZE)
EEPROM parameter placement.
Change these to decide where to place the node ID and bootloader activation byte in the EEPROM memory.
#define	EEPROM_BOOTLOADER_ENABLE_ADDRESS   (uint8_t *)(0)
#define	EEPROM_BOOTLOADER_ENABLE_ADDRESS_LEN   1
#define	EEPROM_NODEID_ADDRESS   (uint8_t *)(EEPROM_BOOTLOADER_ENABLE_ADDRESS + EEPROM_BOOTLOADER_ENABLE_ADDRESS_LEN)
#define	EEPROM_NODEID_ADDRESS_LEN   1
