NEXTION INTRODUCTION

What’s Nextion

Nextion is a Human Machine Interface (HMI) solution combining an onboard processor and memory touch display with Nextion Editor software for HMI GUI project development.

Using the Nextion Editor software, you can quickly develop the HMI GUI by drag-and-drop components (graphics, text, button, slider, etc.) and ASCII text-based instructions for coding how components interact on the display side.

Nextion HMI display connects to peripheral MCU via TTL Serial (5V, TX, RX, GND) to provide event notifications that peripheral MCU can act on, the peripheral MCU can easily update progress, and status back to Nextion display utilizing simple ASCII text-based instructions.

Our mission is to reduce the HMI development workloads.

WHY NEXTION

Nextion Offers an Ease of Use and Cost-effective HMI Solution for You.

Quick and Easy GUI

The Nextion Editor software offers an easy way to create the intuitive and superb touch user interface even for beginners. Add a static picture as background, define functions by components, you can make a simple GUI in minutes. The easy Drag-and-Drop components and simple ASCII text based instructions will dramatically reduce your HMI project development workloads.

The Nextion MEGA IO project – Part 3

As at the beginning of every big project, things seem to advance slowly at the beginning. But if everything is well thought in advance and all the foundations well set, the speed of progress will increase afterwards as you'll see soon! After we defined a very compact an efficient protocol in Part 1 and started implementing it in a Nextion Demo project in Part 2, we need now the counterpart on the Arduino Mega side. That's our today's topic.

The Nextion MEGA IO project – Part 2

After we "invented" an extremely compact and efficient protocol in The Nextion MEGA IO project – Part 1, allowing to control up to 8 MCUs with their up to 12 PWM pins, 32 GPIO pins, and 16 ADC pins each (in case of the Arduino Mega) with only 3 bytes, it's now time to move from theory to practice! Our first goal was and is to make things better than in this project, where we used only 3 PWM channels and only a slightly reduced PWM resolution (7 instead of the theoretically possible 8 bits) for the sake of simplicity. Controlling a RGB LED this way limited the color resolution to 2 millions of colors instead of 16 millions as some attentive readers had noticed and reported back. Thus, we start a huge demo project today, with 12 sliders for the 12 PWM channels of the Arduino Mega, distributed over 2 screen pages, PWM1, and PWM2, having all the full 8bit range supported by the Arduino Mega.

The Nextion MEGA IO project – Part 1

As announced in my last Sunday's blog post, we'll start from this week with the Nextion MEGA IO project which will allow us from a simple Nextion HMI without onboard GPIO, to write all the 12 PWM pins, to read and write all the 32 digital IO pins, and to read all the 16 analog pins of an Arduino Mega! Later, we will even add the option to control the full IO not only of one single MEGA, but several of these. We will also get a downsized version for the Arduino Uno. With the knowledge and tools given successively in this blog post series, you should become a master when it comes to using any MCU for connecting various sensors, LEDs, motors, fans, pumps, relays, or whatever you might imagine!
