Let's take this opportunity to review the evolution of Xiaohongshu's Android version. Over these two years, we have encountered many challenges and gained a lot of experience, which we would like to share with everyone.

Xiaohongshu has evolved from the initial version 1.0

Does STM32’s Hardware I2C Have Bugs?

A legend has been circulating: the hardware I2C design of STM32 has bugs, and it is better not to use it; using software I2C is more reliable.
For a long time, to avoid unnecessary trouble, I have never used hardware I2C, mainly because software I2C is also quite convenient, and it can be used on almost any port.
Recently, I designed a board that just happened to use I2C, so I decided to test whether the hardware I2C is really as bad

Transformations from Embedded Systems to the Internet of Things

Transformations from Embedded Systems to the Internet of Things

After decades of development, embedded technology has been applied in various aspects of our lives. However, embedded systems have always had niche, highly specialized attributes, making it difficult for many from non-embedded fields to approach. In the past decade, the Internet of Things (IoT) has expanded into more fields, including home, business, industry, and agriculture, attracting not only those from the embedded field but also many from non-embedded areas into

Build a Simple Environmental Monitoring Station in 20 Minutes Using IoT

Currently, the Internet of Things (IoT) is considered one of the biggest trends in the market, but the actual development situation is quite different: there are many protocols, components, and tools available, making it overwhelming for developers. Often, they don't know where to start, and the efficiency and outcomes of development are not effectively guaranteed. So how can we improve this situation? Let's hear from the users of

Secrets to Excellent Embedded System Design

As embedded systems become increasingly widespread, we can gain tremendous advantages from the accumulated development knowledge to build better systems.

Engineers never forget the need to deliver projects that meet quality, schedule, and budget goals simultaneously. One effective approach is to leverage the lessons learned accumulated over the years by the embedded systems development community. Below, we will explore some important experiences that have brought best practices to embedded development. Feel free to use them.
