stm8L051 uses the library to build a project

Previously, I developed directly with registers, but it was quite troublesome. I wrote the code directly according to the English technical manual for register development of stm8s103. Now I have switched to stm8L and have to look back at the English documentation. I personally feel that the development efficiency is still very low for a novice like me. Now I have downloaded a firmware from the community to see if I can build a project using the library. (I have previously seen the process of others building projects, but I was not successful because I was not familiar with IAR. Now I have just got it to work without any errors.)

1 First download a copy of the engineering firmware stsw-stm8016. The firmware will be sent to the resources later, or you can download it from the stm32/stm8 community. 

2. Create an iar project 

The project created here is as follows (I have already done it): 

Note: The app file contains the BSP driver we wrote ourselves, the lib file contains the firmware, and there are three files 

These three files are placed directly in the project. 

Finished as follows: 

xxconf.h file is used to load the firmware's .h file 

xxit.h contains some declarations of interrupt functions. 

3 Then create a bsp.c and .h file (this is not necessarily the case here, but it is the case here) 

Then the content of bsp.h is as follows: 

Remark: 

4 Then load the directory where the source code .h file is located into iar: 

5. Finally, main: 

6 After the compilation is successful, you can then quickly copy and paste the development documentation provided in the firmware package^_^. 

7 The above are some key steps for me in this construction project. I made a lot of mistakes in these areas before. 

8 This is just one way I build projects here. There are many developers who have their own directory arrangements for building projects. I personally feel that the document settings are quite good and it is worth my time to study them further. . . . . 

Note: Regarding the issue of locking the file library file mentioned above, you can also click the properties of the relevant file under the file directory, and then remove the option of the "read-only" attribute, and then you can modify the library file directly in IAR.
