Stc serial port download software is installed on the computer, but it can't be used normally. Who can help me find out the problem? It almost killed me.
This should be related to computers. Or your program, see if it is STC-ISP(STC official burning tool)? Or what is it called? PZ-ISP？ Try the burning tool.
Here is the official STC burning tool to see if you are the same.
