Can DEVs be Included in DEVCHANs?

No, you can?t stuff a DEV[] array into a DEVCHAN. It doesn?t fit. A DEVCHAN is a container (a data type/structure ? a block of memory) that only has enough room to hold one DEV and one INTEGER. You can have a DEVCHAN[] array (a bunch of these containers) but each item in the array has to be one DEV and one INTEGER (one DEVCHAN.)

I don?t use DEVCHANs myself (not that there is anything wrong with them) but instead I opt to keep the DEVs separate from the channels/buttons and do something like this.

DEFINE_DEVICE

dvTP1	= 10001:1:0
dvTP2	= 10002:1:0

DEFINE_CONSTANT

INTEGER nButtons[]	= {2,4,6}

DEFINE_VARIABLE

DEV 	dvTPs[]	={dvTP1,dvTP2}

DEFINE_EVENT

BUTTON_EVENT[dvTPs,nButtons] {

   PUSH: {
   
      //to find out which device generated the push you can use
      //BUTTON.INPUT.DEVICE
      
      //or to find out the index into the array of devices you can use
      //GET_LAST(dvTPs)

      //to find out which button was pushed you can use
      //BUTTON.INPUT.CHANNEL
      
      //or to find out the index into the array of buttons you can use
      //GET_LAST(nButtons)
      
   }
}
