Hey, is it possible to send, for example, a simple Windows application written in C# in Visual Studio, datagrid view tables, e.g. 5 rows and 5 columns, to nextion? What is the best way to do it, as a whole file or in rows?
I can handle C#, but I don’t know how to do it with nextion to make it as simple as possible.
You do not need the arduino to do this you can make a 5 x 5 text boxes and write
a program in a timer on the nextion to look at the serial buffer then fill the text boxes , if you use reparse mode you get to control the serial buffer. You need a TTL to RS232 buffer then just plug the nextion directly into a serial port on the PC , if you send the values as comma delineated text you can parse the data and put it into the text boxes.
