Re: sinusoidal PWM
Great!
Yes, that is the duty cycle. Why not modify your array for the 90% instead of doing math here? We want to keep multiplication out of our assembly interrupt handler, otherwise, we will need to change it to a PBP type interrupt. And that would take a lot of time for each interrupt, as it needs to save and restore 70 registers each time it interrupts. If you need it to change dynamically, the beauty of an array rather than a lookup, is that you can change it on the fly (doing math in your main).
