I have been thinking about this content for a long time, but either I got busy or my writing skills were off, so I never got around to it. Today, I’ll finally share it; otherwise, it would be buried deep in my brain. Haha. The content is quite simple; it’s just about setting up the … Read more
The noinit section is familiar to most of us developers working with microcontrollers. If this section is used, it will be automatically allocated by the compiler to a region in the chip’s SRAM (note that it is in the RAM area, not Flash). Variables defined in this section will not be re-initialized during any chip … Read more
Operating System: Windows (MinGW) / Linux Project Format: CMake When setting up a toolchain for your embedded project, you can use the IAR compiler. CLion recognizes it as a C/C++ compiler and collects compiler information. You can also open projects that use the IAR toolchain, which should load successfully. Currently, only CMake-based projects are supported. … Read more
Header File Meanings avr_macros.h includes simplified writing for reading and writing 16-bit registers, along with several bit manipulation functions. comp_a90.h provides brief writing for a large number of intrinsic functions. ina90.h includes the “inavr.h” and “comp_A90.h” files. intrinsics.h provides intrinsic functions that offer the simplest operations for handling the processor’s low-level features: sleep, watchdog, FLASH … Read more
Introduction From this article, we officially step into the Zigbee protocol. This article will start with the basic Zigbee protocol, without using any packaged protocol stack. The content is migrated from a basic protocol template to the project, and has been updated to the code repository. Repository address: https://gitee.com/jeady5/zigbee-emaple Based on today’s project, I will … Read more

This is definitely a good article. Printing with this function is sometimes more useful than any debugging tool, and the kernel’s prink is a true gem. But how does the printf function connect with the UART driver? This article will answer that for you. Like, share, and bookmark it for when you need it. Today, … 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
