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.
