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

Bus Lecture 17: Real Vehicle Automation Testing System Based on LabVIEW

This system focuses on communication-related functions for real vehicles, conducting a rapid functionality survey. For IO operations, such as switching sensors, reminders are provided through a “popup + voice prompt” method, achieving semi-automation. Before the ECU is installed in the vehicle, we need to find ways to conduct HIL testing, such as basic functional logic … Read more
