stvd+stm8l051F3(1): stvd builds stm8l project step by step

stvd version information: ST Visual Develop Version 4.3.9
Microcontroller model: stm8l051F3

Steps for establishing stm8l project with stvd:
1. Open stvd, File->New Workspace...

Select Create workspace and project

Enter the project name in Workspace filename, and the project storage path in Workspace location

Enter the project name in Project filename; enter the project storage path in Project location, and select the compiler to be used in Toolchain, here select STM8 Cosmic;
Toolchain root will automatically obtain the path of the compiler according to the selection of Toolchain

Select the IC model, double-click, and then click OK

Click OK, the preliminary project and project have been established, and the compilation is successful.

The stm8l_led project Source Files adds two files, main.c and stm8_interrupt_vector.c.

The led directory automatically adds main.c and stm8_interrupt_vector.c files.

2. Add the STM8L15x_StdPeriph_Driver standard library.
2.1. Copy the three files stm8l15x_conf.h, stm8l15x_it.h, and stm8l15x_it.c to the led directory.

2.2. Copy the STM8L15x_StdPeriph_Driver folder to the led directory.

2.2. Add stm8l15x_conf.h, stm8l15x_it.h, and stm8l15x_it.c to the stm8l_led project, and then add stm8l15x.h from the inc folder under STM8L15x_StdPeriph_Driver to the stm8l_led project.


2.3. Double-click to open stm8l15x.h and remove the comment symbol of the MCU model used.

The compilation project prompts an error:
Running Linker
clnk -m Debugstm8l_led.map -l"C:Program Files (x86)COSMICCXSTM8Lib" -o Debugstm8l_led.sm8 Debugstm8l_led.lkf 
#error clnk Debugstm8l_led.lkf:68 Debugstm8_interrupt_vector.o: symbol f_NonHandledInterrupt multiply defined (Debugstm8l15x_it.o)
 The command: "clnk -m Debugstm8l_led.map -l"C:Program Files (x86)COSMICCXSTM8Lib" -o Debugstm8l_led.sm8 Debugstm8l_led.lkf " has failed, the returned value is: 1
exit code=1.
Comment the @far @interrupt void NonHandledInterrupt (void) function in the stm8_interrupt_vector.c file because it is defined repeatedly. #include the "stm8l15x_it.h" header file and then compile it.

2.4. Select the stm8l_led project in the stvd software Workspace box, right-click and select New Folder... from the pop-up menu, and enter the name of the new folder STM8L15x_StdPeriph_Driver

2.5. In the stm8l_led project in the stvd software Workspace box, right-click STM8L15x_StdPeriph_Driver and select Add Files to Folder..., and select stm8l15x_gpio.c in the STM8L15x_StdPeriph_Driversrc directory.


2.6. Double-click to open the stm8l15x_conf.h file and comment out #define USE_FULL_ASSERT.

2.7. Change the content of main.c to the following code, compile the project, and compile successfully.

1. //STM8L051/151 and other series shared library functions
   

2. #include "stm8l15x.h"
   

3. 
   

4. //Define LED port
   

5. #define LED_PORT GPIOD
   

6. #define LED_PINS GPIO_Pin_0
   

7. 
   

8. /***********************************************************************************
   

9. ****Entry parameters: None
   

10. ****Export parameters: None
    

11. ****Function Note: Inaccurate delay function

12. ***********************************************************************************/
    

13. void Delay(__IO uint16_t nCount)
    

14. {
    

15.     /* Decrement nCount value */
    

16.     while (nCount != 0)
    

17.     {
    

18.         nCount--;
    

19.     }
    

20. }
    

21. /***********************************************************************************
    

22. ****Function description: Main function
    

23. ****Entry parameters: None
    

24. ****Export parameters: None
    

25. ****Function Notes: LED flashes at a certain frequency
    

26. ************************************************************************************/
    

27. void main(void)
    

28. {
    

29.   GPIO_Init(LED_PORT, LED_PINS, GPIO_Mode_Out_PP_Low_Slow); //Initialize LED port
    

30.   while (1)
    

31.   {
    

32.     GPIO_ToggleBits(LED_PORT,LED_PINS); //Flip LED port
    

33.     Delay(50000);
    

34.   }
    

35. }

At this point, a basic STM8l project has been created. If you need to use other module functions of the microcontroller, add them according to the method of adding stm8l15x_gpio.c. For example, if you want to use spi, add stm8l15x_spi.c to the project.

In addition, the process of establishing a stm8s project is similar to this.
