Nextion lcd font wizard9/5/2023 ![]() The first thing you should do is to take note of your components in the GUI that will interact with the Arduino and take note of their ID, names and page. You should be able to copy and paste code to make the Arduino do what you want. Writing code to interact with the Nextion display is not straightforward for beginners, but it also isn’t as complicated as it may seem.Ī good way to learn how to write code for the Arduino to interact with the Nextion display is to go to the examples folder in the Nextion library folder and explore. Once the GUI is ready, you need to write the Arduino code so that the Nextion can interact with the Arduino and vice-versa. Change line 37, so that you have the following: #define nexSerial Serial Comment line 32: //#define dbSerial Serialĥ. ![]() Comment line 27, so that it stays as follows: //#define DEBUG_SERIAL_ENABLEĤ. There should be a NexConfig.h file – open that file.ģ. Open the ITEADLIB_Arduino_Nextion folderĢ. To make it work for Arduino Uno, you need to do the following:ġ. ![]() This library is configured for Arduino MEGA2560 by default.
