So it's been a while since my lightening talk on Zephir and I realized I…
I’ve pushed a few changes to phpiwire can now use the PWM functions in wiringPi. You can use either the hardware PWM pins or any of the GPIOs by using software PWM. A couple new examples of how to do this have also been added to the repository.
With software PWM comes the requirement to include pthreads, so that’s also linked when you compile the zephir extension.
I’d recommend you do a full clean first before compiling with:
zephir fullclean zephir install
