Problem during execution after installing on Raspberry Pi 3b
sudo ./CameraLED.py state Traceback (most recent call last): File "./CameraLED.py", line 65, in <module> print("State: " + str(led.state())) File "./CameraLED.py", line 53, in state return self.__firmware_request__(self.GET_TAG) File "./CameraLED.py", line 31, in __firmware_request__ result = fcntl.ioctl(self.__vcio, self.IOCTL_MAILBOX, buffer) OSError: [Errno 22] Invalid argument
Tried to build from source the cpp version after building wiringpi:

I know this is years later, but it's more than likely to do with 32-bit vs 64-bit architecture. If you're running a 64-bit version of Pi OS, try changing the IOCTL_MAILBOX = 0xC0086400 instead
