Windows controlled Display?

1

Someone knows how controll the Displays directly from Windows?
thinking about Visual Basic / Studio.

What is the problem ?

  1. connect LCD to COM port using some RS232 module from China RS232 module
  2. you need external +5V power supply for LCD & RS232 module.
  3. Write your program that will send commands to LCD and receive answers. ( you can use Nextion editor for testing It able to work with real COM port )

I want to write a little tool that reads Windows values.(that also works)

But visualBasic only has this Command to send trough SerialPort
SerialPort1.Write()

Thats exactly what you need !
