Gpio channel has not be setup as an output

WebSetup up a channel. You need to set up every channel you are using as an input or an output. To configure a channel as an input: GPIO.setup(channel, GPIO.IN) (where channel is the channel number based on the numbering system you have specified (BOARD or BCM)). More advanced information about setting up input channels can be … Web1. I have an LED connected to a GPIO pin and am using RPi.GPIO to control it. When setting up the GPIO pin, the LED blinks on ever so slightly when being initialized, which I don't want. import RPi.GPIO as GPIO GPIO.setmode (GPIO.BOARD) GPIO.setup (22, GPIO.OUT) GPIO.output (22, False) setMode seems to briefly turn on the LED.

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.
