Compared to STM32, the STM8 series microcontrollers, although less well-known, hold a certain position in industrial control and embedded systems due to their efficient performance and rich peripheral interfaces, among which the I2C (Inter-Integrated Circuit) interface plays an important role. This article will analyze the characteristics of the STM8 I2C interface and explain its advantages … Read more
Communication Protocol What are the differences between synchronous vs asynchronous and serial vs parallel? Communication protocols are fundamental skills that are applicable everywhere. However, very few people can confidently say they fully understand a specific communication protocol. Often, we only use part of the protocol. Hardware Engineer Growth Plan Phase IV: Hard Sound UP Master … Read more
The I²C bus is very common in embedded systems, but recently in a group (possibly a beginner group) communication, I was quite surprised that many people do not even understand the I²C bus basics. Today, I will explain the timing of the I²C bus. Many electronic engineers should know about the I²C bus from EEPROM … Read more
Introduction When it comes to driver development, we must mention the bus; the bus is the bridge for data transmission between devices. Computers categorize buses into three types: data bus, address bus, and control bus, which are collectively referred to as the system bus. Generally, the system bus, internal bus, and external bus are known … Read more
1. Overview The I2C bus is a very popular and powerful bus, commonly used for communication between one (or multiple) master devices and one or more slave devices. Figure 1 shows that various peripherals can share this bus, which only requires two wires to connect to the processor. This is one of the biggest advantages … Read more
There are many serial communication protocols, among which I2C and SPI are very well-known.I2C and SPI are both bus protocols that allow users to perform short-distance serial data transmission. I2C is a two-wire communication protocol developed by Philips (now NXP), while SPI was developed by Motorola. These two protocols are commonly used in electronic devices … Read more
Click the above “Mechanical and Electronic Engineering Technology” to follow us 1. What is I2C Communication I2C (Inter-Integrated Circuit) is a serial communication protocol used for transferring data between integrated circuits (ICs). It was developed by Philips (now NXP Semiconductors) in the 1980s and has become a widely adopted communication standard in various electronic devices. … Read more
Source | Roof Ridge Sparrow | strongerHuang There are many methods for microcontrollers to drive LCDs, and many accompanying examples are available online. However, among the thousands of examples online, which one is your “no.1”? Today, I would like to share an approach to driving LCDs with microcontrollers in an object-oriented manner. Overview of LCD … Read more
