Decoding LEDs
« on: November 15, 2021, 05:46:28 pm »
Hi all,

I've taken it upon myself to try and figure out what those darn LEDs mean on the front of the Cosmo!

From my reading of the kernel module written for the LEDs, it uses certain GPIO pins on the Cosmo PCB. It's also commented in mostly Chinese, with some English.

My question to anyone who has somehow managed to extract the PCB (this is a long shot!), and I'm by no means suggesting dismantling your Cosmo *just* for me ;) - but if anyone sees a GPIO pin that says either 'P0' or 'P1', please let me know - either here, or on the Telegram (Cosmo group, no PMs, thanks). I think there are subdivisions of P0 and P1, but without seeing the PCB I have no idea.

It's my intention to document the LEDs too, probably on OESF - if an admin wanted to pin it, that's great! :)

There's a pdf of a 'teardown' on this post:
I had a quick look at the photos and couldn't see anything relevant, but then I wouldn't know what I'm looking for ???
I have a damaged Cosmo parked for spares, if I get a chance at the weekend I will open it up.
