SDI-12 Example Code

function MySDIInit()

 sdi12.set(sdi_cpo)
 sdi_cpo:release() -- allow the thread to get the object
end

-- Should run inside a thread, as this could take minutes...
function MySDITask(the_thread, the_name)

 sdi12.go(sdi_cpo, sdit)
 while not sdi12.done(sdit) and the_thread:run()
 do
   tool.sleep(250) -- little wait
 end 

 if sdit[1].v
 then
   log.write('SDI device 1 = '..sdit[1].v)
 end
 
 if sdit[2].v
 then
  for n,vv in ipairs(sdit[2].v)
  do
    -- do something with vv
  end
 end
 -- have completed the reading on SDI-12
