F1 smart module has more than twenty spare General Purpose Input-Output (GPIO) pins available for you to use with your own sensors and actuators. Below would like to outline the basics for configuring and controlling the GPIO as output and input pins.
Controlling the GPIO pins of the modules is rather easy. The example below shows how to generate a 1 Hz clock signal at Pin 9.
from machine import Pin import time Pin9 = Pin(Pin.P9, mode=Pin.OUT) while True: print("high") Pin9.value(1) time.sleep(1) print("low") Pin9.value(0) time.sleep(1)
Sometimes, it would be useful to know the state of a pin. For example, you could use the SBOOT button on the Starter Kit to toggle the led.
from machine import Pin import rgbled button = Pin(Pin.P12, mode = Pin.IN) # SBOOT button on Starter Kit while True: if(button() == 1): rgbled.color(0x00003300) # turn LED to Green else: rgbled.color(0x00000000) # turn off LED
