Use standard unit. Do not use register value directly.
It is unfortunately not just a value in Amps, it depends on the hardware
design. There is a kind of "default" table with a 49.9K resistor, but
depending on that resistor the current is different.

led should have standard interface.

Thanks I will investigate, that may indeed be a better abstraction.
Kind regards,
