"\n"
"This plugin controls the General Purpose Digital I/O (GPIO) pins on devices\n"
"like a Raspberry Pi. It creates a single device, with a single output port.\n"

"\n"
"`gpio_slot_offset = <int>` \n"
"The DMX512 slot for the first pin. Slots are indexed from 1.\n"
"\n"
"`gpio_turn_on = <int>` \n"
