[C.CC USERS] Occam-Pi programing question

[Bryant Nelson]

Here is what I got so far. The problem is, all the pumps turn on at the
same time, run for the proper amount of time, then wait for the maximum
wait time. For example, the pump on pin 12 is governing the off time. After
4s all the pumps kick on, 13 is on for 1s, 12 for 2s and 11 for .7s, once
12 is done it waits 4s then everything starts at the same time.

Can somebody help me out?


#INCLUDE "plumbing.module"
PROC do (VAL INT pin, VAL INT timeOn, VAL INT timeOff)
  SEQ
    digital.mode (pin, OUTPUT)
    digital.write (pin, HIGH)
    delay(timeOn)
    digital.mode (pin, OUTPUT)
    digital.write(pin, LOW)
    delay(timeOff)
:

PROC main ()
  WHILE TRUE
    PAR
      do(13, 1000, 2000)
      do(12, 2000, 4000)
      do(11, 700, 1500)
