My question is how fast pwm mode 7 timer2 of the uno works. From reading
the documentation I really could not understand how this mode is supposed
What I could see using a scope is that OC2A register sets the period.
and OC2B register sets the duty cycle. OC2B must always be less than
OC2A to see a change in of state at OC2B pin.
I could not get OC2A pin to change.
If anyone who is familiar with this mode can let me know if this
is how its used that would be awesome.
