This is a simple demonstration of CANSPI Library routines usage. First node initi-
ates the communication with the second node by sending some data to its address.
The second node responds by sending back the data incremented by 1. First node
then does the same and sends incremented data back to second node, etc.

Code for the first CANSPI node:

program Can_Spi_1st

dim Can_Init_Flags, Can_Send_Flags, Can_Rcv_Flags as byte ' can flags

Rx_Data_Len 

' received data length in bytes

RxTx_Data   

as byte[8]      ' can rx/tx data buffer

Msg_Rcvd 

' reception flag

Tx_ID, Rx_ID 

' can rx and tx ID

' CANSPI module connections
dim CanSpi_CS as sbit at

PORTB.B0

CanSpi_CS_Direction 

as sbit at DDRB.B0

CanSpi_Rst 

as sbit at PORTB.B2

CanSpi_Rst_Direction 

as sbit at DDRB.B2

' End CANSPI module connections

main:

ADCSRA.7 = 0                  ' Set AN pins to Digital I/O
PORTC = 0
DDRC = 255

Can_Init_Flags = 0            '
Can_Send_Flags = 0            ' clear flags
Can_Rcv_Flags  = 0            '

Can_Send_Flags = _CANSPI_TX_PRIORITY_0 

' form value to be used

_CANSPI_TX_NO_RTR_FRAME

Can_Init_Flags = _CANSPI_CONFIG_SAMPLE_THRICE 

and ' form value to be

used

_CANSPI_CONFIG_PHSEG2_PRG_ON 

and ' with CANSPIInit
