Perhaps a silly question about automatic resume

(1/3) > >>

MoBe:
Hello, not sure I am in the right forum, if not, I would be happy to ask elsewhere.

I do not have a device, I will need to purchase several devices as part of an art installation. I'm hoping Rockbox would be the solution I'm looking for. This is what I need to happen:

1. The device will be connected to a solar charger 24/7
2. While on, it will loop a sound file
3. The power will be cut through interaction
4. When the power is re-connected, after whatever length of time, the device needs to automatically start playing, even if it was off.

Would the Rockbox "resume on startup" do this?

gevaerts:
Rockbox can be configured to do exactly that, yes. You set the start screen to resume, and you set the playback mode to repeat, and tings should work.

I'm not exactly sure how you want stopping to work, but if you want a clean shutdown if power is cut, also enable "car adapter mode" which will pause playback when external power is cut (and restart when power appears again if the device happens to still be running), and set the idle poweroff setting to something fairly short, that should also work.

Also, don't forget you have the source, so anything is possible :)

MoBe:
Thanks for the reply!

The device will be connected to a solar charger and a photocell "switch" so when it is dark (night/someone covers the photocell) the power supply will be cut from the player and it will stop playing.

My worry was that "startup" means that an "on" button has be clicked, since I don't have a device to test with, I wanted to make sure it would work completely hands free. Idle poweroff  wouldn't work since it has to work continuously unless the photocell reads "dark".

Having the source won't do me much good, I'm not too proficient at coding (or I'd probably opt for an arduino solution).

Thanks again, I'll have to see which player would work best and just make a decision.

:)

gevaerts:
For the power on, most players will do that just fine when power appears, but I'd recommend asking here first for the specific player you have in mind.

MoBe:
Hi again.

Is there a forum you would recommend for me to ask for recommendations? Since each player will be playing one file, all I need is this autoplay function and a robust enough device, as it will be in a waterproof box, outdoors.

Another questions just popped up -
Can Rockbox recognise a power "event"? So that even if its battery is charged it would stop when power goes off and resume with re-powering?

Thank you!
