USB-UART

MultiProg supports working with USB-UART converters ("dongles") through a virtual COM port.

Typically, these are USB adapters based on FT232 series, such as CP2102, CH340, and similar.

Currently, support for Espressif controllers has been added.

Installation​

Make sure you have installed the drivers, and the device is recognized by the system.

Check the echo using the command line (Windows).

  • Short the RX-TX lines on the converter.
  • Open the command prompt (cmd).
  • Type the command mode and press Enter.
  • You will see a list of available COM ports.
  • Remember the port number of your adapter (for example, COM3).
  • Type the command echo TestUART > COM3 (replace COM3 with your port).
  • Type the command type COM3 (replace COM3 with your port).
  • If everything works, you should see "TestUART".

You also can short the RX-TX lines and do same check with any terminal program.
