What do you use (or recommend) for hardware-level PWM on GPIO pins, via a Python interface?
Thanks,
Daniele

It is "hardware TIMED" but not true "hardware" PWM -- I believe they are using hardware timer interrupts to toggle the GPIO for pulse width. It is not a "fire&forget" PWM circuit that runs without OS intervention.
Since the pigpio daemon runs as a kernel process, it doesn't undergo as much latency as doing the GPIO toggling from a user process via the deprecated sysfs
