Any idea if it is possible to change the input intervals on the piface? What I mean is it checks the inputs every 500ms, do you know if it is possible to speed that up a little?

Thanks, could that happen when copying the image of the os?

What does 'digital_read' is not defined actually mean when found as an error when running a program in python

hub

Do you think you could help me with this delay script? I got a lot riding on it.

hub

So I changed to Pifaceio as pf but I am not following the script you listed. Do I need to change some other parts as well? Right now with that change it says line 27 pf.init() ##########<<<<<
pf is not defined

I just don't know where the changes need to be with what you have listed.

I have an error now that is something I have seen before. This error is common with the installation of the piface. If you google it, you can see where many people have this issue. I had it when I installed my piface, but somehow I over came it. Now when I run the new script you gave me, it says: li...

ok, I think I am getting close but here is what I get when I try to run the module. line 25, in <module> win + curses.initscr() also line 33, in initscr fd=_sys._stfout_.fileno()) error: setupterm: could not find terminal do you now what any of these could mean? I looked and looked to make sure I ha...

My apologies for not completely understanding all of that, but I am in way over my head here. Just to clarify. Yes, I have one input. Within that input I have the options of a input signal of 1, 5, 10, or 20 times. All I need to do turn the first relay on then off within seconds, then have the secon...

hub

thanks for your help. So should I insert this in my current script that I am running if so where?

hub

yes, I didn't think of it like that but you are correct. Taking it a step further, the amount of seconds is a variable. I am not sure that it will take 20 seconds to push the button 20 times, because its actually receiving it through one of the set of inputs. Is there a way to set this up then modif...

Can someone help me modify he following script or create a new script for use with the pi face? https://gist.github.com/bulletmark/11126770 I need the be able to press the button or received an input one time in 1 seconds and have the relays turn on and off as in the attached script, then I need be ...

hub

you still with me? Almost done with this project, just need to figure this part out. Thanks in advance!

hub

the smart comment was, how complex can I make it?

hub

My input is automated, the only thing I can work with is the number of inputs within a certain amount of time. The delay is not a problem, if you know how to write it please point me in the right direction.. I am hoping that as I keep working with this scrip I will start understanding, but there is ...

hub

got it. thank you for all your help. I now have the inputs working the switchs/relays and understand how to change the time/delay. I was wondering this: could I modify the script be to say the following: if button is pressed 1 time within 5 seconds connect relay for 2 seconds, but if button/input is...

hub

ok, one more.... how about a script that will allow me to use one button to control both relays. For example, push the button and relay 1 turns on for .5sec then turns off. Then an adjustable amount of time passes, say 5 sec and the second relay turns on for .5 sec then turns off. I re-read the docu...

If I have a device that uses 12 volts can I hook them to the inputs? You're going to have to educate yourself a little about the electronics. No, you can't feed 12v directly into those inputs. Normally, your external device would provide a dry contact, e.g. normally open, which you would wire pin 1...

hub

ok, so on the inputs if you ground the first two screws it is the same as pressing the button, right?

hub

that's great! how do you know all this? I got it like I want it now, other than the input pins. If I have a device that uses 12 volts can I hook them to the inputs? Also, how can I make the pi run this code everytime it boots up, so I don't have to manually do it? I know there is a file I have to ed...

hub

thanks for your help. A couple more questions: 1. What if I wanted it to cycle twice? Would I simply copy and past the code or are there only certain parts that I would copy. For example if you push the button the relay would switch on for the set time, then go off, then turn back on and then off. I...

If you are saying that easy_install is missing then do this instead: sudo apt-get install python-pip sudo pip install pifaceio sudo /usr/local/bin/install-spidev.sh Then run http://pastebin.com/UMmxWVzF as I said. ok I think its working now. so, when I run the command listed, I will use python (a n...

When I try this all I get is command not found. What am I missing?

Can anyone help me with the code to do operate the switches and relays on the Pi Face? I want to push one of the buttons then it connect one of the relay for a predetermined amount of time. Ones this time has been reached it will release. Any ideas where to look for this? My Pi Face is fully operati...

hub

Does anyone know of a way to have the pi shut itself off completely? I can handle to auto boot, I jus need it to shut down (without pulling the plug)

hub

I typed the entire thing out. It was the copy paste that was hanging up. Apparently its not the same as when you type it.
