It is developed following the ideas of VxWorks653. https://gitee.com/personal_chenjl/AnOs The development environment uses Keil uVersion5. The sample program runs on the STM32F427 controller. The system aims to be applied … Read more
This article will rewrite the handcrafted OS – a function running the minimum core code of FREERTOS, as shown in the figure below. Mainly: rewriting vTaskSwitchContext + background tick interrupt automatically switches tasks. In fact, the functionality has been completed in two articles, but it seems clumsy to represent using UART. This article aims to … Read more
▼Click the card below to follow the public account ▼ Since we started working with microcontrollers, we have known about a software called KEIL. When developing microcontrollers, we use C language or assembly language. We know that neither of these languages can be directly loaded into the microcontroller. Regardless of whether it executes or not, … Read more
What is a map file? In simple terms, a map file is a mapping file that combines programs, data, and IO space after compilation by the compiler. Many highly skilled engineers first think of analyzing the map file when encountering memory overflow or out-of-bounds situations. The map file provides important information such as function sizes … Read more

Author | strongerHuang WeChat Official Account | Embedded Column Generally speaking, programming on microcontrollers is done in either assembly or C language, and it is rare to use C++ for development. So, can we really use C++ for microcontroller development? The answer is definitely yes! Below, I will discuss some content about writing a LED … Read more
Follow+Star Public Account, don’t miss exciting content Author | strongerHuang WeChat Public Account | strongerHuang Recently, I have received some questions from readers: Can Keil use GCC to compile code? Can Keil use other compilers? When you use other GUN toolchains for compilation, you may encounter errors like the following: — Error: can't execute 'as'— … Read more
Recently, a friend in the group asked the question: How can I use a higher version of the compiler? This friend provided an image: From the image above, it can be seen that the version of Keil MDK used by this friend is not the latest version. So, how do I operate if I want … Read more
