nextion 4.3 tft lcd brands

When I first bought this display, I had expectations of getting it up and running in an evening. WRONG. There is a LOT to learn if you"ve never used a "smart" display like this. I connected mine to an Arduino Mega as part of a weather station project. The physical connection is simple, with 4 wires, 2 for power, and 2 for a serial TX/RX connection. The part I didn"t understand before purchasing is that you don"t just send data to this display and it appears... you actually need to learn how to program the display using the Nextion screen editing software (MS Windows ONLY)... and once you program the display, you then have to write the software on whatever device (arduino in my case) to send the data to the display.... so this is a multi step process. Learning how the Nextion editor works (give yourself a week). Designing what you want the display to do (another week). Programming the display. Loading the display code onto the actual display, which can be done using a microSD card (the easy way).

Once the display is programmed, you THEN need to learn HOW to send data to it... which is complex... and can be done two ways that I know of... first, you can use the Nextion libraries, which provide an API to send data to the display... or you can avoid the libary, and learn the ascii codes sequences that mimic what the Nextion API sends to the display, and simply send those as text over the serial port... either way is NOT simply and will require a lot of googling and reading and practicing and looking at other people"s code. I"m a degreed computer engineer (now retired) and it took me a few weeks of research before I managed to become even mildly proficient... The display can do some amazing things with graphs, dials, buttons, progress bars, colors, fonts, etc... I have barely scratched the surface. The nice thing is that instead of writing hundreds of lines of display code, you actually program the Nextion to do most of the work, leaving the arduino to focus its resources on other non-display related tasks. I"m glad I put the effort in.

There is also a fairly good user forum on the Nextion website. A lot of it is geared towards professions developers, but there are DIY users asking questions. I got quick responses to a lot of questions when I was first learning. To sign up, you do need to create an account and provide an email address, but it was worth it. I was impressed with the support I got.

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 NX4827T043 4.3" TFT LCD HMI Touchscreen Display is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human and a process, machine, application or appliance. Nextion is mainly applied to the Internet of thing (IoT) or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.

Nextion includes a hardware part (a series of TFT boards) and a software part (the Nextion editor). The Nextion TFT board uses only one serial port to communicate.
