WebApr 11, 2024 · At the most basic level, GPIO refers to a set of pins on your computer’s mainboard or add-on card. These pins can send or receive electrical signals, but they aren’t designed for any specific purpose. This is why they’re called “general-purpose” IO. This is unlike common port standards such as USB or DVI. WebPins start from 1 \n or : BCM GPIO number \n direction - INPUT or OUTPUT \n [pull_up_down] - PUD_OFF (default), PUD_UP or PUD_DOWN \n [initial] - Initial value for an output channel \n [delay] - Time in milliseconds to wait after exporting gpio pin "},
