1 Introduction Sometimes, our applications require variables to maintain continuity or to preserve the state, for example, during Bootloader jumps or resets where certain critical variables should not be initialized. Different compilation environments have different settings. This article summarizes this operation and introduces the methods used in Keil, IAR, and CubeIDE. The chip used in … Read more
Teacher Zhu, this tutorial is based on notes I整理ed from a recent competition. I remember that there was very little information online about the KEA128 application in smart car competitions. I have graduated but couldn’t bear to delete these materials. If you think this article might be useful for everyone (especially those just starting with … Read more
Introduction All STM32 series products come with a CRC peripheral that provides hardware support for CRC calculations, saving code space for applications. The CRC checksum can be used to verify the correctness of data during transmission and can also be used for integrity checks during data storage. In IEC60335, CRC checks are accepted for verifying … Read more
IAR for ARM is a top-tier integrated development environment, fully known as “IAR Embedded Workbench for ARM”. It is developed by the world-renowned Swedish company IAR Systems, which specializes in embedded systems development tools and services. Founded in 1983 and headquartered in Uppsala, Sweden, the company went public on NASDAQ OMX Stockholm on January 4, … Read more

01 Introduction When it comes to Keil and IAR, you might think their integrated development environment interfaces are quite outdated and not user-friendly. But here’s a fact: whether you are a beginner in microcontroller programming or an experienced developer, the usage of Keil and IAR is significantly higher compared to other tools, and it’s not … Read more
Today, I will share with you the hardware UART peripheral debugging output mechanism under IAR. In the embedded world, outputting print information is a very common auxiliary debugging method. With the help of print information, we can easily locate and analyze program issues. There are many ways to implement print information output in embedded application … Read more
Keil and IAR microcontroller programming software are currently two of the most widely used microcontroller programming tools. There are certain differences in their usage. In this article, I will explain the detailed method of creating an STM32 project using IAR programming software, hoping that everyone can gain something from this article. STM32 is a very … Read more
Microcontroller programming software is typically dominated by Keil and IAR. When choosing suitable microcontroller programming software, one can base the decision on project requirements. This article focuses on IAR microcontroller programming software, mainly explaining the methods for project debugging using this software. If you have any questions about the content to be discussed, let’s learn … Read more
Click the blue text to follow and learn embedded systems! Students often ask me if a certain microcontroller uses Keil for program design. In fact, this question requires consulting the official information of the relevant microcontroller, as any microcontroller will have some programming development environment provided by the official after its release. Otherwise, how would … Read more
