Pulse width modulation (PWM) on AVR Studio Stack Overflow

20120228· For example, how do you set a PWM rate of, for example, 42% with it? Also, the code size is big, it can be done in a much more efficient way. Also, you waste a 16 bit timer to do 8 bit operations. You have 2x 8 bit timers (Timer/Counter 0 and 2), and one 16 bit timer, Timer/Counter 1. It''s also a bad idea to set unused portpins to output.
