Foreword Sail against the current, if you don’t advance, you will retreat! ! ! Processes and threads What is a process? Answer: A process is the smallest unit for the operating system to allocate resources. It is an instance of a running program, or a dynamic execution of an application. For example, when you open […]
STM32 uses interrupts and DAM to complete serial communication
(1) Serial port protocol and RS-232 standard 1. Introduction to serial port protocol Serial Communication is a very commonly used serial communication method between devices. Because it is simple and convenient, most electronic devices support this communication method. Electronic engineers often use this communication method to output debugging when debugging equipment. information. In computer science, […]
Serial communication based on interrupt/DMA mode
1. Introduction to serial communication protocol and RS-232 and the working principle of USB/TTL to 232 module 1. Serial protocol and RS-232 standard: (1) Serial port protocol: Serial Communication is a very commonly used serial communication method between devices. Because it is simple and convenient, most electronic devices support this communication method. Electronic engineers often […]
Serial communication based on interrupt/DMA mode
Experimental tasks: 1. Understand the serial port protocol and RS-232 standard, as well as the difference between RS232 level and TTL level; Understand the working principle of the “USB/TTL to 232” module (taking the CH340 chip module as an example). 2. Use the HAL library (or standard library) method to set the USART1 baud rate […]
Interrupt, DMA serial communication
1. Serial communication based on interrupt mode 1. Configure the project through CubeMX 1. Configure the project through STM32CubeMX (1) Set up RCC Set High Speed Clock (HSE) to Crystal/Ceramic Resonator (2)Set SYS Here you need to set the Debug column to Serial Wire (3) Set USART Here I chose the USART1 configuration and set […]
