When using a sequencer to send UDS services over LIN with ID 0x3C and NAD 0x55, why not send a LIN message with ID 0x3D afterward for the slave to respond? ​

How to implement loop counting for periodic messages? ​

Answer

If you has database and want update signal value periodically:

  1. First you need config the message as periodic.
  2. Then you neen use OnCan API to listen the message send/receive.
  3. Use setSignal API to update signal value.
ts
import { setSignal } from 'ECB'
let val = 0

Util.OnCan(0x142, (data) => {
   setSignal('Model3CAN.VCLEFT_liftgateLatchRequest', val++ % 5)
})

demo

Without database:

  1. Just use output API to output the frame with any value you want.
ts
import { output,CanMessage,CAN_ID_TYPE} from 'ECB'
setInterval(() => {
  const canMsg:CanMessage = {
      id: 0x111,
      data: Buffer.from([0,1,2,3,4,5,6,7]),
      dir: 'OUT',
      msgType:{
        idType: CAN_ID_TYPE.STANDARD,
        remote: false,
        brs: false,
        canfd: false,
      }
    }
   output(canMsg)
}, 1000)
