Embedded – Timer and External Interrupt Simulated UART

by
Embedded - Timer and External Interrupt Simulated UART

The following are the general steps and example code for simulating UART (Universal Asynchronous Receiver-Transmitter) communication using timers and external interrupts (taking STM32 as an example, using C language). This method can achieve basic UART communication functionality through software simulation without hardware UART peripherals or when additional UART features are required. #include “stm32f10x.h” // Define … Read more
