Advantages of UART Outputting Analog Signals

Advantages of UART Outputting Analog Signals

01 UART Outputting Analog Signals 1. Introduction Yesterday, someone commented on the “Serial Music” VLOG, raising a very good question. That is, what are the advantages of using the microcontroller’s UART output signal low-pass filtered to obtain an analog signal compared to using traditional PWM output signal low-pass filtered to obtain an analog signal? In … Read more

Implementation Method of Custom UART Communication Protocol

Implementation Method of Custom UART Communication Protocol

When we study microcontrollers, the first thing we may encounter is lighting up (GPIO), and then comes the serial port (UART). The serial port is a commonly used communication interface and is a necessary knowledge to master in embedded systems. However, I have found that many friends only know how to use the serial port … Read more
