– 1 background 240×400, add as Picture resource #0 We have chosen 115200 baud in our requirements, so locate the lines dbSerial.begin(9600) Īnd change these to our 250000/115200 baud dbSerial.begin(250000) Ĭreating the HMI for the Basic 3.2″ Nexiton NX4024T032_011 We will use the Serial Monitor and set its baudrate high (no need to waste more MCU time than is needed), then we will also need to configure for Nextion. Locate the nexInit() function, here we configure the baudrate for Serial Monitor and Nextion.

Then locate the line defining nexSerial #define nexSerial Serial2 Locate the line #define DEBUG_SERIAL_ENABLE Iteadlib comes preconfigured for the Mega 2560 – nexSerial to use our hardware serial Serial2 Select and Open the Library zip file from step 1c.īe sure to READ the library readme.md file for directions Step 3Ĭonfigure the Nextion Library for use with the Mega 2560.Īs the Mega 2560 has 4 serials we will configure for Install the Iteadlib Arduino Nextion Library – 4 straight pins from Male/Male 2.54mm headerĭownload the Iteadlib Arduino Nextion LibraryĪ) goto Iteadlib Arduino Nextion Library github pageī) click Clone or Download and select Download ZIPĬ) Save to a location you’ll remember on your hard drive (for Next step) Step 2 – included Nextion 4 wire Power/UART cable – Nextion timer to evaluate and update status based on value – MCU to toggle LED on D13 on Button press/release – MCU to change pages in response to Button release This basic project will meet the following requirements

In this post, I will show how to setup an Mega 2560 for use with Iteadlib with a basic Nextion HMI.
