4.2.5 LED Interface Status Display
The LED interface is used to indicate the operational states for CAN
and Ethernet using the LEDs. The UDP or TCP interfaces displayed
on the status LEDs have to be selected. No selection is possible for
CAN, but the interface has to be configured.
An LED interface is generated with
mkif led.
The directory name is selected automatically and is
/if/led0 for the
interface.
It is possible to select which LEDs go with which interface using the
adjustable filter defines (refer to section
4.3). Example:
With the setting
/if/led0/fin +hd1 +ld23
the states of interface 1 are assigned to the LEDs for CAN error and
CAN traffic (identified by hd) and the states of interface 2 and
interface 3 are displayed on the BTP error and BTP connection LEDs.
The states of other interfaces are not displayed. The interface IDs can
be accessed with the command ls (refer to section
4.5.2).
Default setting (the CAN interface has the interface number 1):
/if/led0/fin +hd1 +l
Possible options:
<option> ::={<reset>}
reset re-initializes the LEDs
