Hi Marcus, Thanks for the reply, I got it working now! I had missed PIO when I read through it all, it was getting late!
I have reread the info and I think latch is used when writing to the memory. I'm not sure how flipflop is intended to used, it seems to be the inverse of PIO. Yes I am still working with pyowfs, my control system is still running my original code which calls digitemp, but I have almost finished re-writing it with a few improvements using pyowfs Once again, thanks for your help Mick On Wed, 2010-09-22 at 01:13 +0200, Marcus Priesch wrote: > Hi Mick, > > i just digged in my sources ... ;) > > you need to set PIO.A to 0 (or 1?) to cunduct the output (it's open > drain afaik) and set PIO.A to 1 (or 0?) to release the output ... > > latch, flipflop and sensed are all for reading the inputs and detecting > if there have been and edges there ... > > to test (and find out if you need to set PIO.A to 0 or 1 to conduct) you > could use the following : > > o +5V > | > | | > | | 10kOhm > | > PIO.A --o--------o <- Measure voltage here > if its 0V the output is conducted > if its 5V the output is open > o > | > --- > > well hope that holds ... as its little bit late already ;) > > ps: fine that you're using pyowfs ;))) > > all the best, > m. > > > Am Dienstag, den 21.09.2010, 23:40 +0100 schrieb Mick Sulley: > > Hi, > > > > I have just bought a couple of DS2406 (as D2PC from Embedded Data > > Systems).
