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

Control Servo motors with Nextion HMI – Part 1
Over the last weeks, I got several mails from readers asking about the use of servo motors (or short, servos) together with Nextion HMI. The ones wanted to control a few servos directly from the Nextion's (Enhanced and Intelligent series) GPIO, others suggested to extend the Nextion Mega I/O project to allow controlling servos. The scientific approach is to gather information before taking a decision or even starting a development, thus, let's look at how servos work and how they are controlled, first. And then, let's see how the Nextion HMI can be used for that.
Building a Countdown timer – answering a reader’s question
After reading the following question of a reader, let's call him "J.", in a Nextion Display related group on Facebook, I decided spontaneously to make it a small project for this Blog: "Hello I'm new in using Nextion Intelligent Display! Can someone help me? I want to make a timer where the user can enter how many seconds he wants to run and also show how much time is remaining before it ends. Thanks a lot if you can help me💜"
Boosting the Nextion Mega I/O project with new knowledge (6)
Up to now, the highlight of our ongoing Nextion Mega I/O project is the ADC page which allows to monitor all 16 analog input pins of an Arduino Mega at once. With little modifications in the UI design, by putting either a Number or a Float component for a specific channel, we can select the desired display format without caring about conversion of or scaling the reading. The timer event code will chose the right formula by detecting the component type beforehand. All that is really great, but what if we do not need (or not all the time) all 16 channels? Is there a way to permanently disable (freeze/hold) the one or the other channel in order to reduce the workload of the Mega's ADC and the amount of data transferred? The answer is yes, and thanks to what we saw in the last Sunday Blog, it's easy-peasy!
Working with bit fields – optimize your code
Bitwise logical operations and packing data into bitfields is a very elementary programming technique - in fact, every microprocessor uses it internally to achieve "higher" goals like addition, subtraction, multiplication, division, and more. Nevertheless, many people who write amazing software in "high" languages are not really comfortable when it comes to bit manipulations, even if these can, as we have often seen in the Nextion Sunday Blog's demo projects, make your code more compact, using less memory and running quicker. Since I get more and more reader's feedback in that sense, I decided to make a compact writeup, giving you the required knowledge at hands, not only to decipher but also to create amazing things.
Universal UI on-screen help framework for Nextion HMI
In the Nextion user forums, a participant from Europe, let's call him M., asked an interesting question. What he wants to achieve is activating a "Help" mode on his Nextion project. That means that after activating this help mode, the user would click on an arbitrary component and instead of executing the component's event code, a help screen with explanations would be displayed. Since in his project, there are nearly 1000 components on several screens, reworking each single component's event code to decide if the event code should be executed or the help screen displayed, is definitively not an option. So, he thought that he'd use a TouchCap component to intercept the event chain before the component's own event code was executed, to decide if, in case the help mode was active, the help screen would be displayed. But his problem was that the component's own TouchPress and/or TouchRelease event code would still be executed afterwards, probably going to a different page, which would prevent displaying the help text correctly...
