Hello, my friend.
First of all, you have to tell me how large the screen size you are.
Second, we are the 4.3 inch screen, you must match your screen.
Third, check your serial port is connected well.
Finally, you can do a project that you want to match with your screen, try using SD card.
If it is not good, you can provide us with your screenshots or photos.
Many thanks to take about me :)
The connection between arduino and nextion looks working I did this test and can change the brightness and page of the demo screen on the request of the arduino.
So I will put an ds card and see if that ok.
However I would like to fix the issue concerning the link editor to tft, because it is not friendly to copy the project to sd then put it in the device.
What would the causes of this issues ?
Once my tft file is compiled, I have to put it in the sd card at the root level ? correct ? or something else I must know ?
Many thanks, your help is really appreciate
// Open serial communications and wait for port to open:
First, make sure that your nextion and computer connections are correct. Computer TX-----nextionRX computer RX------nextionTX
Second, you can try our simple example.
Third, ensure that you have the serial port to open, and can work.
