Hi Phil :palm:
You lost me at " Hi Rob " :lol: :lol: :lol: only joking mate .
Arh I keep forgetting your Hydro project ,great stuff . Two real world applications for a small microprocessor very interesting , all way above my pay grade at the moment , I am at the make LED blink stage lol :palm: ,That will be one hell of a saving on the grease bill ,money that could be better spent elsewhere on the project .
I was hoping to build/come up with something similar . I want to log when and for how long a battery has been on charge . :scratch:
All the best to you and yours Phil :beer:
Rob
PS you full recovered from your cycling mishap ?

Hi Rob,
3 weeks ago the only python I knew of was something that squashed and ate you in a nightmare!
I too was pleased when I got an LED to flash for the first time.
I wrote tons of stuff in BBC Basic but a long time ago. I don't think that knowing Basic helps at all with Python.
If you look for online documentation you have to be very careful that your looking at the documentation for the version of Python you're using as things can change dramatically between versions.
Timing things looks fairly simple when you see that datetime.now() returns something like 24/12/2015 15:06:44.995179 which is accurate to the microsecond. However as I found out actually getting microsecond timing of events needs interrupts. If you only need a time to the odd second or so it should be straightforward.
My latest cycling mishap did for my shoulder. It's very slowly getting better. I just have to remember not to try to lift anything heavy above shoulder height.
I've just been planing 0.5mm off the top of the front door. We've just had the hall, landing and two lots of stairs plastered - everything's damp and the door had swollen. Hopefully we should be dry when the family come round for tea tomorrow.
I've got the Pi, Function Generator, Pulse Generator on the floor in the living room with wires trailing between. I'd better put them away before tomorrow or else I'll get some grief! I started with a mouse and monitor connected as well but now I've installed VNC and can drive it all from my laptop.
Cheers.
Phil.

Hi Rob, loads of shields and projects about - like you said googling brings up a lot. I'm guessing that a simple square wave will be made with a simple pin going high and low - either on an interrupt or delayed loop. Dead simple, pin1 go high, delay, pin1 go low, delay and loop. I can see from the online projects that there is more to getting nicer wave forms. I've got s few play stepper motor drivers so I'll be giving them a test to get my scope going. Rob, have you looked at the Mikroelectronica stuff? - their easyPic 6 board got me flying with some proper pic coding in C. Well worth a look at if you have some spare cash and admittedly it isn't the cheapest.
Phil, just wanted to say hello and merry Christmas. I was in touch with you weekly for many months then dropped off the face of the Earth when I moved house a year ago. Hope all is well.

Hi Chris,
Hello and a Merry Christmas to you.
You'd see a difference in our hall now now it's plastered. I've earned some Brownie points by getting this done.
I might replace some of my equipment with stuff from BangGood - it would take up a lot less space.
It's all got to disappear later!
Cheers.
Phil.
