[sdiy] Driving SSI2144 freq control with PWM from a microcontroller

[Eric Brombaugh]

Amusingly, I have a patent on this approach:

https://patents.google.com/patent/US5774084A

Not the greatest thing ever and it expired a few years ago. Whenever I 
see an argument about how broken the patent system in the US is I think 
of this one.
