4.1 Basic Concepts of Serial Communication Serial communication is a commonly used communication method, which refers to data transmission between devices through a Serial Interface. There are several basic concepts of serial communication: 4.1.1 Serial Communication Serial communication refers to the transmission of data bit by bit, transmitting only one bit at a time. Compared … Read more
To master the STM32 microcontroller, one cannot do without serial communication. Serial communication uses a protocol called the serial communication protocol to manage data transmission, which controls the data flow during transmission, including data bits, baud rate, parity bits, and stop bits. Due to its simplicity and ease of use, serial communication is widely applied … Read more
Embedded electronic devices are collections of various circuits (processors or other integrated circuits). In order to exchange information between these independent circuits, they must follow the same communication protocol. To accommodate different needs, engineers have defined hundreds of thousands of communication protocols, which can generally be divided into two categories: parallel or serial. 1. Parallel … Read more
1. From Polling to Interrupt Many students prefer polling over interrupt-driven operations. Is this related to our nature? Everyone likes to have everything under control and dislikes being interrupted. We often have experiences where we are talking to someone and suddenly receive a phone call, and after the call, we can’t remember what we were … Read more
Arduino has a rich set of external interfaces, and the biggest difference from Raspberry Pi’s IO ports is that Arduino has analog input interfaces that can measure analog values on IO ports. The communication scheme between Arduino and Raspberry Pi via serial (Serial) generally has two methods: one is through Raspberry Pi GPIO serial communication, … Read more
Do you know what Arduino is? Do you know what Arduino can do? Today, let’s get to know Arduino! Arduino is a convenient, flexible, and easy-to-use open-source electronic prototyping platform. It includes hardware (various models of Arduino boards) and software (Arduino IDE). It was developed by a European team in the winter of 2005. Its … Read more
