Download and Run Programs
The development board supports SWD download, USB download, and serial port download
When downloading SWD, ST-Link or WCH Link downloaders can be used. Here is an introduction to SWD download. For other download methods, please refer to the documentation in the development board documentation package or consult the internet.
The steps for downloading SWD are as follows (using the CH32F103C8T6 development board as an example):

• A. Firstly, ensure that the BT0 and BT1 pins of the MCU remain low, as shown in the following figure:
  The BT0 and BT1 pins of CH32F103C8T6 are connected to GND using jump caps .

• B. Find the SWD interface of the development board and connect it one by one with the pins of the emulator (theoretically, any emulator that supports the SWD protocol supports it), as shown in the following figure:

  • Connect to ST-Link:
  • Connect to WCH-Link:

• C. Open the KEIL tool software and click the button shown in the following figure:

• D. Click the Debug button in the pop pop-up interface, and then select the emulator in Use.

  • If using ST -Link , please select ST -LINK Debugger

  • If using WCHWCH-Link , please select CMSISCMSIS-DAP Debugger
    As shown in the following figure:

  • Using ST ST-Link:

  • Using WCHWCH-LinkLink:

• E. Power on the development board and click the Settings button next to Use (as shown in the previous operation). The following interface will pop up, indicating that the emulator has successfully connected:

  • ST -Link connection successful:
  • WCH-Link connection successful:

• F. Click the Flash Download button to enter the flash settings interface, as shown in the following figure (if flash has been selected, this step can be omitted): If you want the program to automatically r un after successful download, you need to check Reset and Run . Otherwise, after successful download, you need to press the reset button or power off to restart before running the program.

• G. Click on the Add button (as shown in the above figure) to select flash. Generally, the first one is selected (the algorithm has already been processed), and once it is selected, click on the Add button below to exit, as shown below:

• H. Click the OK button and the OK button to exit the settings interface, as shown in the following figure:

• I. Click the download button to download the program, and the following prompt will appear, indicating successful download, as shown in the following figure:

• J. If the display module displays characters and graphics normally, it indicates that the program has run successfully.
