Someone knows how controll the Displays directly from Windows?
thinking about Visual Basic / Studio.
What is the problem ?
- connect LCD to COM port using some RS232 module from China RS232 module
- you need external +5V power supply for LCD & RS232 module.
- 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 !
