For me it works perfekt. I would like to discuss it, but if think it's overkill at all it makes no sense.
- Because of the LED the resulting resistance is nearly 1.4kOhms (The LED helps to visualize the succes of start. Waiting for OS to be ready could be a little confusing)
- GPIO27 is low when the OS running and high through external pull up when the device is switched off.
- The transistor blocks the hard reset when OS is running.
- Then the push button triggers only the shutdown.
Please tell me if there's something wrong. May be there is still a hidden mistake.
I wanted to use the integrated switch of my volume device. This was the starting point.
Keep calm and feel free to forget this solution. Image may be NSFW.
