Hi,

thank you so much for the code and explanation, I managed to mostly modify it to make it work as a very simple macro keyboard for OBS and Zoom for me.

One issue I have is that when I want to switch scenes in OBS (I have two buttons on the keypad assigned to this) it works flawlessly when OBS is my active window, but when I have Zoom open in the foreground, it becomes very random when I hit the buttons. Zoom doesn't use the hotkeys I use for OBS and this also happens with other apps like Chrome. It does work, but I might have to hit the keys 10 times to activate the key function or maybe it works 3 times in a row without a problem.

I also have a button for muting my mic in Zoom and (inelegantly) another one to unmute me. I haven't figured out a good way to have the mute button light up when I am muted and switch the led off when i click the key again to unmute myself. Here I have a similar issue where I click the button and it somehow activates the key press multiple times at once.

I have next to zero experience with Python, just learning it now, so what is wrong in the code? I just paste the modified bit below (instead of your hid_keyboard.py).

> keypad = RGBKeypad()
> kbd = Keyboard(usb_hid.devices)
> 
> key0 = keypad[0, 0]
> key1 = keypad[1, 0]
> key2 = keypad[2, 0]
> key3 = keypad[3, 0]
> key4 = keypad[0, 1]
> key5 = keypad[1, 1]
> key6 = keypad[2, 1]
> key7 = keypad[3, 1]
> key8 = keypad[0, 2]
> key9 = keypad[1, 2]
> keyA = keypad[2, 2]
> keyB = keypad[3, 2]
> keyC = keypad[0, 3]
> keyD = keypad[1, 3]
> keyE = keypad[2, 3]
> keyF = keypad[3, 3]
> 
> key3.color = (255, 100, 50)
> key3.brightness = 0.2
> 
> while True:
>     if key3.is_pressed():
>        keypad.clear()
>        key3.color = (255, 100, 50)
>     if keyC.is_pressed():
>        kbd.send(Keycode.CONTROL, Keycode.SHIFT, Keycode.NINE)
>        keyD.clear()
>        keyC.color = (60, 220, 240)
>     if keyD.is_pressed():
>        kbd.send(Keycode.CONTROL, Keycode.SHIFT, Keycode.EIGHT)
>        keyC.clear()
>        keyD.color = (60, 220, 240)
>     if keyF.is_pressed():
>        kbd.send(Keycode.ALT, Keycode.A)
>        keyF.color = (155, 120, 255)

Any help at all would be much appreciated! Thank you.

I have been using your code in MicroPython and it worked great. All of the LEDs and buttons functioned properly. I then realizes to use USB_HID inputs I needed to switch to CircuitPython.

Here is the issue, the buttons remain working and I can get USB_HID output, but the LEDs will no longer work. I placed the rgbkeypad.py file in my lib folder and I have run other CircuitPython files with no issue on this board. I have made sure that my soldered connections on the raspberry pi pico are good for the SCK and MOSI (GP18 and GP19) pins. I can link some of my code that I have been using below and maybe that will help but I cannot figure out this problem.

from rgbkeypad import RGBKeypad
import time

keypad = RGBKeypad() # initialize keypad

keypad.color = (0, 0, 0) # initialize keypad lights off


WHITE = (255, 255, 255)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
YELLOW = (255, 255, 0)
PURPLE = (128, 0, 128)
OFF = (0, 0, 0)


def colorPress(y):
    if y == 0:
        return WHITE
    elif y == 1:
        return PURPLE
    else:
        return GREEN

def functionPress(x, y):
    return print(key.y, key.x)

animation_speed = 0.2 # seconds per state


while True:
    for key in keypad.keys:
        if key.is_pressed():
            key.color = colorPress(key.y)
            functionPress(key.x, key.y)
            while key.is_pressed():
                time.sleep(0.05) 
            key.color = OFF 
            
    time.sleep(0.05)
