After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.Recently, when playing with a ESP32 based NodeMCU 32S and especially with its WiFi configuration, I did as (I guess) everybody does: I loaded an example sketch to learn more about the Wifi library. When you set up the ESP32 as an access point, creating its own wireless network, everything is pretty straightforward. You can easily hard code the Wifi name (SSID) and the password. But what about the client mode ? Perhaps one needs to use it in different environments. And then, a hard coded network name and password are definitively not the best solution. Thus, I thought, why not use a Nextion HMI for a dynamic WiFi setup functionality?

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 at 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.

Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.

This solution includes hardware part - a series of TFT boards and software part - Nextion editor. Nextion TFT board uses only one serial port to do communicating. Let you get rid of the wiring trouble. We notice that most engineers spend much time in application development but get unpleasant results.

In this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time in programming, which will reduce your 99% development workloads. With the help of this WYSIWYG editor, GUI designing is a piece of cake.

This is a powerful 3.5"" HMI, which is member of Nextion family. Features include: a 3.5" TFT 480 x320 resistive touch screen display, 4M Flash, 2KByte RAM, 65k colors.

A wide variety of nextion options are available to you, such as call center and on-line technical support, others and free spare parts.You can also choose from 4:3, nextion,As well as from new, {2}, and {3}. And whether nextion is clear, black, or {3}.

I honestly can’t think of a single mass-produced product in North America or Western Europe that uses TJC/Nextion in any capacity. If the product has any degree of complexity at all, there will be an MCU somewhere already, which means you don’t really need the Nextion MCU. That pretty much just leaves the touchscreen itself.

I am as small-time as it gets and I sell a handful of devices on Tindie, and for my volume the tradeoff between development time and device cost makes the Nextion feasible. But that math only works out if you’re running extremely small volumes.

For example, say I can get a Nextion 2.4" Basic for $10 in volume. A similar 2.4" touchscreen can be had for < $2 without the TJC/Nextion bits. TJC/Nextion provide a very nice development environment that any idiot can use (I’m exhibit A here). That $2 touchscreen is going to require more work from the development team. If I’m going to sell 100,000 units, that’s $800k I could spend on a development team, or more realistically, $50k I could spend on development and $750k I could put in my pocket.

There’s no way for the math to work out in TJC/Nextion’s favor when there’s any sort of scale involved. The product development environment is well suited for rapid development, but the pricing and limitations of the environment mean it’s only suited for prototyping or short-run projects.

Further, you have the issue outlined in the OP. No organization can be confident that the part they spec from Nextion today is going to be the part they receive in their next order. If you question Nextion about it, they’ll stop communicating with you and ban any accounts you’ve opened with them. These sorts of supply chain issues mean NOBODY in their right mind would spec this part. It’s single-source, and the single source is not trusted or accountable.

That’s why it’s so hard to understand the overall posture of the Nextion team w/r/t the hobbyist/enthusiast community. They’re convinced that they have a industrial/commercial part that they’re selling, and so they actively push away hobbyists and prototype shops while chasing after commercial users. Unfortunately, due to the issues outlined above, nobody in industry would consider this platform for anything that would be produced at scale. So what they’re left with are commercial users who either can’t get their shit together to develop against the bare LCD, or who operate at very small volumes.

I know that those users are out there, and according to @Fjodor there apparently are several in Eastern Europe, but man it feels like Nextion is missing a major market, which is the only market where their products make sense, simply by being jerks to anyone that isn’t in the commercial space.

Nextion has a range of HMI displays, these are displays where the layout is programmed in the display itself and only the data (and some minor layout data like colors) are sent to the display via a serial line.

I also played with MMDVMHost and the Nextion displays, but wanted some extra functionality. So I made NextionDriver, a helper program (Linux only) to provide extra"s to your Nextion display.

Warning : there are also some other manufacturers of similar displays, often very cheap (i.e. TJC), but these displays are not Nextion displays, can not load Nextion tft files, need their own editor etc.
