Not long ago, the 2020 World Artificial Intelligence Conference (WAIC) just concluded in Shanghai, reigniting the concept of artificial intelligence in the industry. … Read more
In the process of developing and debugging applications using STM32 microcontrollers, we often encounter various anomalies. A significant portion of these issues are related to the power supply. The power supply is critical and essential for any electronic product, yet during actual development and debugging, we sometimes inadvertently neglect it. Here, I share a few … Read more
Recently, some friends asked me how to learn embedded systems. I have always wanted to write an article about the learning path, but due to various reasons, it was delayed until now. I have finally completed this article. I personally transitioned from STM32 to driver development. During my second year of research, I studied the … Read more

2020 was such a special year. Due to the pandemic, this New Year could not be celebrated with friends and family like in previous years. Everyone chose to stay at home, waiting for good news like they await spring. While ordinary people manage and protect themselves, we also see the admirable healthcare workers, the most … Read more
Hello everyone, I would like to recommend an article by my friend, the mixed bag master. There are many programming ideas to learn in Linux, and many experts apply these ideas and mechanisms to microcontroller programming. For example: cola_os introduced in the Embedded Mixed Bag Weekly | Issue 4, and the well-known RT-Thread. Also, the … Read more
This article is based on a query from a certain STM32 user, slightly modified and organized. The content may be a bit extensive, involving STM32 timer synchronization applications, the correlation between timer trigger events and ADC, interrupt handling based on ADC events, and DMA transmission based on timer events. Ultimately, it requires attention to many … Read more
