Copy Code To Clipboard
if (MsgFlag and _ECAN_RX_OVERFLOW <> 0) then
...
‘ Receiver overflow has occurred.
‘ We have lost our previous message.
end if
ECAN_MASK Constants
The
ECAN_MASK
constants define mask codes. The routine ECANxSetMask expect one of these as their argument:

ECAN_FILTER Constants
The
ECAN_FILTER
constants define filter codes. The routine ECANxSetFilter expect one of these as their argument:
