Building a CircuitPython StreamDeck with Pi Pico Key Combination Problem


# Python code goes here

Are you trying to build a CircuitPython StreamDeck using a Pi Pico but facing a problem with key combinations? Don’t worry, we’ve got you covered! In this article, we will explore three different solutions to solve this problem.

Solution 1: Using the `keyboard` Library

One way to solve the key combination problem is by using the `keyboard` library in Python. This library allows you to listen for key events and perform actions accordingly. Here’s an example code snippet:


import keyboard

def on_key_event(event):
    if keyboard.is_pressed('ctrl') and keyboard.is_pressed('shift') and keyboard.is_pressed('a'):
        # Perform your desired action here
        print("Ctrl + Shift + A pressed")

keyboard.on_press(on_key_event)
keyboard.wait()

This code listens for key events and checks if the combination of Ctrl + Shift + A is pressed. You can replace the print statement with your desired action.

Solution 2: Using the `gpiozero` Library

Another solution is to use the `gpiozero` library, which provides a simple interface for controlling GPIO devices. Here’s an example code snippet:


from gpiozero import Button

button1 = Button(2)  # Replace with the GPIO pin number you are using for the first button
button2 = Button(3)  # Replace with the GPIO pin number you are using for the second button
button3 = Button(4)  # Replace with the GPIO pin number you are using for the third button

while True:
    if button1.is_pressed and button2.is_pressed and button3.is_pressed:
        # Perform your desired action here
        print("Button 1, 2, and 3 pressed")

This code continuously checks if all three buttons are pressed simultaneously. You can replace the print statement with your desired action.

Solution 3: Using the `RPi.GPIO` Library

If you prefer a lower-level approach, you can use the `RPi.GPIO` library to directly control the GPIO pins on the Pi Pico. Here’s an example code snippet:


import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BOARD)
GPIO.setup(2, GPIO.IN)  # Replace with the GPIO pin number you are using for the first button
GPIO.setup(3, GPIO.IN)  # Replace with the GPIO pin number you are using for the second button
GPIO.setup(4, GPIO.IN)  # Replace with the GPIO pin number you are using for the third button

while True:
    if GPIO.input(2) == GPIO.HIGH and GPIO.input(3) == GPIO.HIGH and GPIO.input(4) == GPIO.HIGH:
        # Perform your desired action here
        print("Button 1, 2, and 3 pressed")

This code checks if all three buttons are in the HIGH state, indicating that they are pressed simultaneously. You can replace the print statement with your desired action.

After exploring these three solutions, we can conclude that the best option depends on your specific requirements and preferences. If you prefer a higher-level approach with easy-to-use functions, Solution 1 using the `keyboard` library might be the best choice. However, if you want more control over the GPIO pins and prefer a lower-level approach, Solutions 2 and 3 using the `gpiozero` and `RPi.GPIO` libraries, respectively, are better options.

Choose the solution that suits your needs and start building your CircuitPython StreamDeck with Pi Pico without any key combination problems!

    1. I completely disagree. The `RPi.GPIO` library is outdated and unreliable. There are much better alternatives available now that provide more features and stability. Dont settle for mediocrity when there are superior options out there.

  1. Solution 2 is the way to go! Who needs complicated libraries when gpiozero can do the job effortlessly? #simplicitywins

    1. I respectfully disagree. While gpiozero may offer simplicity, it lacks the versatility and advanced features of other libraries. Sometimes complexity is necessary to achieve the desired outcome. #functionalitymatters
