trying to use "or"

mikea

I have 3 sensors and dont want them to get "stuck" in a repeat loop if the trigger has moved into the zone of another sensor. i want the code to say ...repeat until motion is sensed in zone 2 or zone 3 (if its currently in zone 1) so its position is updated. I think im not using the correct "or" operator. Ive tried |,or,^.Any help would be appreciated.-mike

if ina[1]==1

repeat until ina[2]==1 or ina[3]==1
outa[pin]~~

There is nothing wrong as such with your usage of boolean or. What are you expecting to happen and what does in fact happen? For debugging purposes you could display (LED/serial) the state of ina[2..3] inside the loop. The example below is based on your fragment. It waits for an event in zone 1 then idles in a loop waiting for events in either zone 2 or 3 which will be provided after 5 seconds. Then it simply indicates that it left the loop (LEDs on pins 16..23, demoboard).

VAR
  long  stack[32]
  
PUB null

  dira[1..3]~~
  dira[16..23]~~
  cognew(buttons, @stack{0})

  repeat
    if ina[1]
      !outa[16]                                         ' in zone 1
      repeat until ina[2][COLOR="#D3D3D3"]{== 1}[/COLOR]or ina[3][COLOR="#D3D3D3"]{== 1}[/COLOR]
        !outa[17]                                       ' waiting
        waitcnt(clkfreq/4 + cnt)
      !outa[23]                                         ' event in 2/3
      
PRI buttons

  dira[1..3]~~
  waitcnt(clkfreq + cnt)
  outa[1] := 1                                          ' zone 1 event
  waitcnt(clkfreq*5 + cnt)
  outa[2] := 1                                          ' zone 2 event

  waitpne(0, 0, 0)                                      ' keep "buttons" alive

kuroneko thanks, i see my problem now. i didn't apply the "or"s to the other 2 zones.-mike
