Programming PIC Microcontrollers in BASIC - mikroElektronika

Description If at least one full receive buffer is found, the function extracts and returns the message as byte. If none found,

FALSE value is returned. CAN must be in mode in which receiving is possible.

Parameters:

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)

Example

res = CANSPIRead(id, Data, 7, 0)

5.2.4.9 CANSPI Library Constants

You need to be familiar with constants that are provided for use with the CAN module. All of the following constants are

predefined in CANSPI library.

CAN_OP_MODE

These constant values define CAN module operation mode. CANSetOperationMode() routine requires this code. These values

must be used by itself, i.e. they cannot be ANDed to form multiple values.

const CAN_MODE_BITS = $E0 ' Use these to access opmode bits

const CAN_MODE_NORMAL = 0

const CAN_MODE_SLEEP = $20
