sub function CANSPIwrite(dim id as longint, dim byref Data as byte[8], dim
DataLen as byte, dim CAN_TX_MSG_FLAGS as byte) as byte
CAN must be in Normal mode.
id - CAN message identifier. Only 11 or 29 bits may be used depending on mes-
sage type (standard or extended).
Data - array of bytes up to 8 bytes in length
DataLen - Data length from 1 thru 8.
CAN_TX_MSG_FLAGS - Value formed from constants (see section below)
If at least one empty transmit buffer is found, given message is queued for the
transmission. If none found, FALSE value is returned.
CAN must be in mode in which receiving is possible.
id - CAN message identifier
Data - array of bytes up to 8 bytes in length
DataLen - Data length from 1 thru 8.
CAN_TX_MSG_FLAGS - Value formed from constants (see below)
If at least one full receive buffer is found, it is extracted and returned.
If none found, FALSE value is returned.
