About the compilation speed when compiling STM32 with MDK [Copy link]

 

The most commonly used compilers for developing STM32F are generally MDK and IAR. IAR is relatively simple and has slightly better compilation efficiency. MDK simulation effect is better, and most people first come into contact with keil, so it may be faster to get started. I also often use iar and MDK. The MDK project is large, so the compilation speed is naturally slow. Sometimes it is very annoying to compile for a small modification for a long time. In fact, there are some tips in MDK to improve the compilation speed: 1) Make the files that do not need to be modified in the project into library files. There are many detailed tutorials on the Internet about how to generate and load lib, so I will not go into details here. The author's original project took about 1 minute and 2 seconds to compile. I compiled the files that did not need to be modified into lib, added them to the project, and recompiled. The compilation time was only 17 seconds. Of course, this is related to the computer and the project. 2) Remove some unnecessary compilation options, such as debugging information, as shown below: After this optimization, the compilation speed can be increased by about 5-10 seconds. Of course, this is related to the project and computer configuration. 3) Remove unnecessary source files and unused functions. 4) In addition, if you are familiar with registers, you can directly operate on registers, which is faster than directly calling library functions, but of course not too obvious. 5) The computer configuration is higher, this is a must-have skill^_^ 6) You are welcome to add other improvement tips, thank you^_^ This content was originally created by EEWORLD forum user 懒猫爱飞.

    I've learned a lot! I'm still in the process of getting started, and my projects are very small. I haven't noticed that the compilation takes too long, usually only a dozen seconds at most, which is within the tolerable range.

Change to version 6 of the compiler.

Find it in the C/C++ tab.

You can also configure the project to group the code by function

You can also edit the library, with the debug option and open the library project, you can single-step into the library for debugging

The key is to uncheck the browse information. Try it with the latest mdk5.27 version https://armkeil.blob.core.windows.net/eval/MDK527pre.EXE

The update is so fast, it's already version 5.27, and I'm still using version 5.24^_^

Yes, you can update it. At least you should use the official version 5.26. 5.27 has many new features that are good.
