STC-LINK simulation download tool (special for core version)
STC-LINK chip will automatically detect 0x7F mode to realize automatic power-off programming, which is very reliable and convenient.
For the device on the circuit board that connects the P31/P30 serial port to the USB interface, it can be directly connected with the USB cable.
For devices with only P31/P30 serial ports on the circuit board, DuPont cable can be used to connect to the array pin.
Note: If the core board needs to be downloaded, it needs to be used with the downloader. The development board does not need to
