Subject: Sinus Table

Hi

I want to create sinus wave (64 half step) with pwm output

my peak value vary from 100 to 255

how can I calculate sinus value in optimal time

I try some code

with 20 Mhz 16c73

each calculation take 120 micro second

if you know faster code please help me.

Thank you.

 

 

Me, I would precalculate the values and put them in a lookup table.
