Driver Installation
Win 10, Win11 system without installation driver, plug and play.
The CDC serial port driver must be installed in Windows 7 and 8; otherwise, the virtual serial port function cannot be used.
(Driving principle, can not see: Inf file for Windows 10. Copy the usbser. inf file to Windows 10. Usbser. inf file can be used as a common driver configuration file for CDC serial port devices in Windows7, with SourceDisksNames and SourceDisksFiles annotated. Apply to all CDC devices, no matter which device, and once installed, plug in other CDC serial devices will automatically install.)
1. First, insert the DAPLINK device, ignore the error "failed to install driver", open device Manager, right click on the corresponding device, and choose Update driver software from the menu:

3. Detailed configuration:
- "Select "SW" mode, not JTAG;
- The download speed is up to 10M. If the download line is too long and the contact is not good, burning may fail. Please reduce the download speed.
- Select "Autodetect" to automatically detect;
- This string of numbers + English, proving that the MCU has been detected.
