Microcontroller: Choosing Between DAC and PWM for Audio Output? Test Data Reveals the Answer!

Hello everyone, I am Xiao Chen. Today, let’s discuss a practical topic: how can microcontrollers output audio signals? Currently, there are two mainstream solutions: directly using a DAC (Digital-to-Analog Converter) or using PWM (Pulse Width Modulation) for analog output. Both methods have their pros and cons, and many beginners can easily get confused. Today, I … Read more
