Using a 2.8" Nextion HMI LCD Touch Display with Raspberry Pi

[jcvamp]

Hi. I am building a portable gaming system using a Raspberry Pi 2 Model B, and I've found the 2.8" Nextion HMI LCD Touch Display online. It says it's compatible with the Pi, but I want to be sure that I know how to connect it before I buy it. Does anyone know where I can find information on how to connect it to my Raspberry Pi?

Thanks.

This is the device (http://www.robotshop.com/uk/28-nextion- ... wwodArIJLQ).

It is a serial interface, so just connect it to the serial port of the RPi. From the datasheet I see it wants 5V power, the serial output is maxx 3.2V. So no need for a level shifter? Free the serial port of the RPi before your program can access the Nextion.

There is PC software , Windows iirc, to program the Nextion. And then write your program on the Pi. Itead website has more info.

Thanks for the response. Which port on the RPi is the serial port? The GPIO header?

GPIO 14 (TX) and 15 (RX). Note that the levels are 3.3V!
