Sequentialy Controling Piface Outputs

Hi Colin,

You should try the code here:

https://medium.com/conectric-networks/playing-with-raspberry-pi-traffic-lights-89e0d1cb51fd

There are three articles, and if you follow them (they are all short exercises) by the end of it you'll be simulating traffic lights, which is not far removed from the type of thing you're trying to do sequentially too.

Then, you can use the same code style to create your own program, but inserting whatever instructions are used for the PiFace board, which it sounds like you're ok with, because you mentioned you can control outputs from the command line.

To wait for a button press, you can use a while loop, here is some information:

Hi Shabaz

Many thanks for your most helpful reply.  I shall take a look at that today and see if I can work it out from there.  However if any one else has any input I would be most grateful.

Colin.

Let me state up front I am not a formally trained programmer. I refer to my skills as Resurrectionist or Frankenstein programming.

Resurrectionists were paid  body snatchers. They exhumed the bodies of the recently dead for anatomists in the United Kingdom during the 18th and 19th centuries.  In Mary Shelley’s  classic horror novel Frankenstein, Dr. Frankenstein stitches together an assortment of stolen body parts and attempts to imbue life into his creation.

I cull Internet search returns looking for code parts I can reuse. Before starting a project I usually have to read some basic documentation (i.e. manual) to get an idea of what I am looking for. I suggest grabbing the documentation for gpiozero, I think 1.5 is the latest version. Take a look at the examples of a using a button and timing.

I have a button activated routine that is body snatched and a timing routine that is also body snatched. They are in two different scripts that I rolled up into the attached zip file. It would require you to take the switch routine from one script and the timing routine from the other script an make your own Frankenstein from the parts.

Many thanks for your helpful and prompt reply.  I am sure I can use some of these body parts in my own grotesque Frankenstein creation.

Best wishes

Colin.

Many thanks to the two gentlemen who responded to my plea for help.  Your inputs assisted me a lot and I am now sorted.

Best wishes

Colin..

Good luck. Touch base if the body parts I provided don't line up. The button routine is fairly common. The timing sequence was developed by a very good programmer friend of mine. His ability to take a concept and turn it into a program is unbelievable. I worked with him for a number of years and never absorbed as much as I would have liked.

Great, I am now pretty well sorted with just some tidying up to do.

Thanks again.

Colin.
