Keil5mdk installation (free)

Whether it's 51 still 32 Single chip microcomputer , Need a compiler programming to achieve the corresponding functions of the chip ​. Nowadays, the common single-chip microcomputer compilers are Keil and IAR, With the advance of the times ,Keil It has basically become a mainstream tool ,IAR Fewer and fewer people are using it , It may still be used in Colleges and universities ​.

Today is mainly about Keil Installation , I sorted out the materials I needed ,​ As shown in the figure below ：

2. open  File->License Management

3.   Copy CID, You need to use

4. Again , use “ Run as administrator ” open pj machine

5. The operation is shown in the figure below , It is mainly to copy the production code

6. Paste the copied code into the box below , You can see that this is a success

The third step ​： Click on  Keil.STM32F1xx_DFP.2.3.0.pack Direct installation , There are no complicated steps in this step , Direct installation

Step four ： After completing the above three steps, you can select your own chip for programming , However, library function support is still needed in programming , The function clock here is for users of library functions , I need to match myself . If you use HAL library ​ It can be used STM32CubeMX Build project , You don't need your own , You can skip this step .
