Programming PIC Microcontrollers in BASIC - mikroElektronika

These constant values define flags related to reception of a CAN message. There could be more than one this flag ANDed together

to form multiple flags. If a particular bit is set; corresponding meaning is TRUE or else it will be FALSE.

e.g.

if (MsgFlag and CAN_RX_OVERFLOW) <> 0 then

' Receiver overflow has occurred.

' We have lost our previous message.

const CAN_RX_FILTER_BITS = $07 ' Use these to access filter bits

const CAN_RX_FILTER_1 = $00

const CAN_RX_FILTER_2 = $01

const CAN_RX_FILTER_3 = $02

const CAN_RX_FILTER_4 = $03

const CAN_RX_FILTER_5 = $04

const CAN_RX_FILTER_6 = $05

const CAN_RX_OVERFLOW = $08 ' Set if Overflowed else cleared

const CAN_RX_INVALID_MSG = $10 ' Set if invalid else cleared

const CAN_RX_XTD_FRAME = $20 ' Set if XTD message else cleared

const CAN_RX_RTR_FRAME = $40 ' Set if RTR message else cleared

const CAN_RX_DBL_BUFFERED = $80 ' Set if this message was hardware double-buffered
