LIN2.1 规范中有这样几句话,实在不好理解,请各位大侠指点迷津!
1、The purpose of an event triggered frame is to increase the responsitivity of the LIN cluster without assigning too much of the bus bandwidth to the polling of multiple slave nodes with seldom occurring events.
2、All subscribers of the event triggered frame shall receive the frame and use its data (if the checksum is validated) as if the associated unconditional frame was received.
3、If the unconditional frame associated with an event triggered frame is scheduled as anunconditional frame the response shall always be transmitted (i.e. behave as a scheduled unconditional frame).
