A method of making a device based on a single USB port to a multi-type multi-channel serial port

 

The utility model belongs to the technical field of embedded hardware debugging devices, in particular to a device based on a single usb port to multi-type multi-channel multi-type multi-level serial ports.


Background technique:

Currently, the closest existing technology in the industry:

The original usb-to-serial device is only a single usb port to multiple serial ports, but the type of serial port is single, or the serial port level is fixed, it can only debug the 3.3v serial port, and can only be used for the debugging of one kind of equipment. Different types of serial ports (232, 485, ttl, etc.) of different devices require different adapter cables. For notebooks with only 2-3 usb ports, except for the port used by the mouse, the usb port is stretched.

To sum up, the problems existing in the prior art are:

The output serial port type of the existing usb-to-serial port is single, and the serial port level is fixed, which can only be used for debugging of one device.

The difficulty of solving the above technical problems:

The existing equipment has a single serial port type, and the serial port level is fixed and can only debug the 3.3v serial port.

The significance of solving the above technical problems:

It can meet the requirements of multiple serial ports, direct connection between different levels, analyze serial port operation command sequence, help embedded developers save debugging modules, save debugging time, and improve work efficiency.
