Function Definitions

Basic GPIO

GPIO.setmode(mode)
Sets the desired GPIO mode.

Argument	Options
mode	ROCK, BOARD, BCM

GPIO.getmode()
Returns the current GPIO mode in the form of ROCK, BOARD, or BCM

GPIO.gpio_function(channel)
Returns the current function of a GPIO export in the form of GPIO.INPUT, GPIO.OUTPUT, or GPIO.UNKNOWN.

Argument	Options
channel	ROCK, BOARD, or BCM number

GPIO.setwarnings(state)
Sets the desired warning mode.

Argument	Options
state	True, False

GPIO.setup(channel, direction, pull_up_down, initial)
Configures a new GPIO export.

Argument	Options
channel	ROCK, BOARD, or BCM number Note: To setup multiple channels, send multiple values, e.g. [14, 15]
direction	GPIO.IN, GPIO.OUT
pull_up_down	GPIO.PUD_DOWN (default), GPIO.PUD_UP
initial	GPIO.LOW (default), GPIO.HIGH Note: If multiple channels, accepts multiple values, e.g. [GPIO.LOW, GPIO.HIGH]

GPIO.output(channel, value)
Sets the output state of a GPIO export.

Argument	Options
channel	ROCK, BOARD, or BCM number Note: To output to multiple channels, send multiple values, e.g. [14, 15]
value	GPIO.LOW, GPIO.HIGH Note: If multiple channels, accepts multiple values, e.g. [GPIO.LOW, GPIO.HIGH]

GPIO.input(channel)
Returns the current state of a GPIO export.

Argument	Options
channel	ROCK, BOARD, or BCM number

GPIO.cleanup(channel)
Cleans up the specified GPIO export. If no channel is specified, cleans up all GPIO exports.

Argument	Options
channel	ROCK, BOARD, or BCM number Note: To cleanup multiple channels, send multiple values, e.g. [14, 15]

PWM Outputs

p=GPIO.PWM(channel, frequency)
Creates a new PWM object "p"

Argument	Options
channel	ROCK, BOARD, or BCM number

p.start(dutycycle, pwm_precision)
Starts the background process "p", with desired duty cycle and precision

Argument	Options
dutycycle	Number between 1 and 100 (%)
pwm_precision	GPIO.HIGH (default), GPIO.LOW

p.stop()
Stops the background process "p"

p.ChangeFrequency(frequency)
Change the frequency of "p"

Argument	Options
frequency	Number (Hz)

p.ChangeDutyCycle(dutycycle)
Change the duty cycle of "p"

Argument	Options
dutycycle	Number between 1 and 100 (%)

Interrupts

GPIO.wait_for_edge(channel, edge, bouncetime, timeout)
Pause execution until the desired interrupt is triggered.

Argument	Options
channel	ROCK, BOARD, or BCM number
edge	GPIO.RISING, GPIO.FALLING, GPIO.BOTH
bouncetime	Debounce time in milliseconds (optional)
timeout	Timeout in milliseconds (optional)
