Add hardware/software support for activity LED

[Nexus9090]

Just an idea, could future revisions of hardware and software have an activity LED?

So the LED blinks once a share is submitted, useful for boards that are headless with no display just to show some activity.

Software should turn the LED on for 100-200ms upon submission of a share, just so it looks like a quick flash.

Thanks

It’s been done already.

Thanks, but this isn't really what I had in mind.

Given what I'm thinking of amounts to toggling a GPIO line at the appropriate time, the solution you've presented is seriously and unnecessarily over engineered.

This is what I had in mind.

An LED attached to the accessory port, a little bit of code to flash it.

The code is working but needs tidy-up, I'll share it once I've done that.
