Can the intvlm8r support usb-only cameras?

[greiginsydney]

I've been asked if the intvlm8r can be tweaked to support the Canon SL3 and other cameras that only have a USB interface.

As it stands today that's a hard no.

The Pi is the brains of the action, but it's purely there for management (and not always running due to its current consumption).

The Arduino calls the shots - metaphorically and literally (I think that holds up grammatically) - using an old-skool emulation of the shutter button.

Changing the intvlm8r so the Arduino asks the Pi to fire a shot (with the latter doing so via USB) is going to be a challenge, not the least because the I2C interface between them is 'Master/Slave', and the Pi can only be the master in this pairing. That means the slave can't tell the master what to do, which is what this would require.

Hypothetically it might be possible with a hardware mod to the board, but I'm running low on spare IO pins on the Arduino...

Leave it with me and I'll ponder it for a bit.
