Related settings when KEIL 5 downloads the program to the STM32F103ZET6 chip

1. Click the magic wand pointed by the arrow to open the project settings. (You can also open the magic wand under Project)

2. Under the Device tab, select the chip used in the project. On the right is the relevant information about the selected chip (I use STM32F103ZET6, select STM32F103ZE)

3. The crystal oscillator under the Target tab is related to software simulation. We download it to the hardware and then debug it without setting it. The starting address and size of ROM and RAM are as follows. They refer to the starting address and size of ROM and RAM of the actual hardware. The default is OK.

4. The Output tab is as follows, turn on Debug information and function jumps when reading code

5. Under the Listing tab, select all the ones in the red box. The purpose is to record detailed information (in the project.map file) when the program is finally linked. My English is not very good, so some translations may not be very accurate.

6. C/C++ tab:

　　　　The purpose of adding the USE_STDPERIPH_DERIVER string is to include the stm32f10x_conf.h header file (the string can be found in the stm32f10x.h file). The stm32f10x_conf.h header file contains the header files of the standard peripheral drivers. When you need to use a standard peripheral, you only need to add the corresponding macro definition.

　　　　The optimization level is usually set to the default level during normal debugging. It can be adjusted appropriately when the project is completed. It is best to turn on all warning messages during normal debugging. It is important to note the include file path at the bottom. You need to add all the header file paths used in the project (usually header files added by users themselves)

7. All the defaults in the Linker tab correspond to the settings in ROM and RAM in the previous Target tab.

8. The left side of the Debug tab is software simulation, and the right side is hardware simulation (it is more appropriate to call it hardware debugging, which is mainly to correspond to the left side). Select the corresponding debugger in hardware debugging (I use ST-Link)

Click the Settings button in the hardware debugging section in the figure above, and a dialog box as shown below will pop up. Select SW mode under the Debug tab (note that it is the Debug tab in the dialog box that pops up after clicking Settings).

Select the Flash Download tab in the dialog box above, check and add as shown in the figure below.

At this point, all download-related settings have been completed. You only need to compile without errors or warnings to download the program to the STM32 chip.
