Hi all, I am in the process of writing 3 instructables on how to use the Nextion displays with your Arduino Uno. In this first part I will show you how to connect your Nextion display to your Arduino Uno. We will also cover how to detect a button tap without the library and with debugging enabled. I am not using the library, because I've found the code to lack explanation and my Arduino sketches don't want to compile when adding the libraries.

Next you have to tell the IDE what Arduino board you are using and which serial port is used. Select Tools -> Board and select “Arduino/Genuido Uno” or whatever you are using. Now go to Tools->Port and select the serial port (dev/tty/ACM0 in a Linux / MAC environment, COMx in a Windows environment). Aug 10, 2017  I opened up the device manager, the arduino wasn't connected was there even though there was a USB connecting the arduino to the computer. Confused, I unplugged and replugged the USB cable to the arduino.

This project will be a simple button on the Nextion, switching a LED on and off. • Open the nextion editor. • Create a new HMI file (File > New > Rename > Save). • Choose your display size (don't press OK yet!). • Orient the display (Click the 'Display' tab on the current window > Choose orientation > Click OK). • Generate a font - this is quite silly, but absolutely necessary (Tools > Font Generator > Choose a size > Choose a style > Enter a font name > Click 'Generate Font' > Save the font in the same directory as your HMI file. • Add generated font (Just click 'OK' on the pop up window).

• From the toolbox on the left, add a button. • Resize it (if you want to). • Add a touch event (In the 'Event box', bottom-middle-ish, choose the 'Touch Release Event' tab > Check the 'Send Component ID' checkbox).

• Compile the file (under the menu bar there is a bar with compile button). • Put the file on your SD card (Go to File > Open build folder > Copy the.tft file > Paste it to your SD card). • Note: Make sure the.tft is the only file on the SD card and that the card is formatted to FAT32. • Insert the SD card into the Nextion.

• Power on the Nextion (use the adapter inside the box OR connect the red wire to 5V of an on Arduino and the black wire to ground on the Arduino). • Wait for the program to upload.

I suspect somewhere that the problem is in the Nextion LCD or configuration (with nextion editor). But I ordered my Nextion 7' 1 week ago, and I will receive it within 1-2 weeks. Maybe there is some small difference with the 4,2' I'm using at the moment. I will be happy to try it out then. 1/Did you measure the 5V on the display. Is it really 5Vdc?: I noticed ( and is commonly known) that they are sensible to low voltage. I got problems because my voltage was 4,8V ( slow or no reaction).

2/ I suppose that the grounds of mega and nextion are connected with each other? Best regards Karl.
