caused by the Sino-US trade war
has caused heated discussions in the electronics industry. It not only reflects that Chinese companies are lagging behind in the...[Details]
In Windows environment, the source code is encoded in UTF-8. If the source file created by STM32CubeMX contains Chinese comments, then using STM32CubeMX to regenerate the source code will cause the C...[Details]
1. The first project We are going to create the first project, which is mainly for project analysis, so that we can understand how CubeMX works and how to trace the code logic. Okay, no more nonsense...[Details]
introduction STM32 has many registers, which are difficult to remember, so the official packaged two sets of library functions. One is the standard library, but the official has not updated it on F7,...[Details]
I used STM32CubeMX V4.22.1 to generate a project including EHT and Lwip. The debugging has been abnormal. After careful inspection, the following problems were found: 1. The hardware uses LAN8720A, b...[Details]
