Click the blue text above: IoT Inn Serial communication plays a very important role in embedded development. It is often used to debug systems, print necessary debugging information, and help us analyze and locate problems. Many common peripherals also support serial protocols, such as WIFI modules, Bluetooth modules, 4G modules, fingerprint modules, PM2.5 sensors, formaldehyde … Read more
Background Knowledge of Communication Interfaces Ways of Communication Between Devices Generally, the communication methods between devices can be divided into parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the direction of data transmission, it can be divided into: … Read more
Overview With the development of the Internet of Things (IoT), more and more devices need to connect to the cloud. These devices include various instruments, industrial equipment, collection devices, and sensors, most of which use serial ports (RS232, RS485). Therefore, IoT gateways such as serial-to-TCP and serial-to-WiFi can be used to transmit data to the … Read more
Communication Methods Between Devices Generally, the communication methods between devices can be divided into two types: parallel communication and serial communication. The differences between parallel and serial communication are shown in the table below. Classification of Serial Communication 1. According to the data transmission direction, it can be divided into: Simplex: Data transmission only supports … Read more
The article about the module is about to begin, and I plan to write a series of beginner and intermediate tutorials on modules and STM32 in the future. Generally speaking, manufacturers of the ESP8266 module will periodically upgrade the firmware inside the module and release it, so we must also master the method of upgrading … Read more
