Trouble In Implementing A DAC Using PWM/Timer Method To Be Used In A VOIP Project
my project is Voice over IP prototype I want to implement a DAC that takes the digital sound and get it back as analog and I found that the best way is to create it using PWM/timer method using C langauage because I want something cheap and I won't buy a DAC chip. The problem is I couldn't find a C code that implements DAC using PWM/timer method that works on ATMega128 because I am totally a beginner and I still can' write a code myself. please help me
