Re: battery powered pi, implement real power button?

Hi Mangiari

Sorry for not responding sooner, I've not received notifications for some reason..

Have a look at YouTube suppiups for a UPS that I've designed and made. You can also contact suppiups@gmail.com and I'll get you setup.

Re: Raspberry Pi3 project using GPIO and LEDs

Additionally,

I like the when_held method over the when_pressed in that it eliminates the possibility of getting on the wrong side (opposite functioning) of an edge based method.

Re: Raspberry Pi3 project using GPIO and LEDs

Hello and thank you again What I have is a DAC that unmutes itself using a GPIO pin GPIO22, so that pin is reserved and functions via it's own driver, aside of anything here in this post. What I would like to to is read that pin internally if possible, rather than connecting another pin to it to rea...

Resources for hiring python coder

Hello Wondering if there are any good resources for hiring experienced python coders for a small GPIO oriented project that I have. I don't think I will have the time to learn to code for what I need and have to focus my resources elsewhere for the time being. I hired some people in India some time ...

Re: Confirmation of gpio-poweroff Behavior

Thanks Phil

I hoped that the overlays would take care of business by themselves. Wasn't aware that there would be other dependencies.
At least i've got a workaround at the moment. It;l most likely be incorporated better in the not distant future.

So if I am reading this correctly.. Setting both overlays GPIO21 is just an indicator of the PI status, coming up as soon as it can, and dropping low after all systems flushed? GPIO20 is the input from a button or other method, pulling low, initiating the shutdown process? I ask because for the whil...
