The PWM at full value was not considered as an "active" channel so if no
other channel was used the timer used to mange PWM was not started. So
when another duty value was set the PWM timer restarted and there was a
visible glitch when driving LEDs. Such a glitch can be seen with the
following code (assuming active-low LED on pin 0):
p = machine.PWM(machine.Pin(0))
p.duty(1023) # full width, LED is off
p.duty(1022) # LED flashes brightly then goes dim
This patch fixes the glitch.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
