nextion lcd display for sale

If looking for the suitable nextion LCD display in bulk, it is a good idea. Buyers should consider buying lcd displays in bulk, which are a good option for them.

Buyers should consider buying lcd based on their specific needs and budget. If lcd is a good option for buyers, you should consider purchasing lcd from the wholesalers on Alibaba.

When looking for a suitable nextion lcd display, it is easy to find where the nextion LCD display is easy to clean. Due to the built-in lcd display, it is easy to find other displays that have easy-to-use settings.

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?Although the Nextion MIDI I/O interface  has been primarily designed as an add-on for Nextion HMI screens to transform these in fully autonomous MIDI devices as shown in previous blog posts here, it is also of great use for any Arduino based electronic music project! Many MIDI projects for Arduino suffer from a lack good hardware support. There are sophisticated code, excellent libraries and an infinity of use cases, but afterwards, things tend not to work in a rather rough environment in the studio or on stage. That"s because two resistors and a few Dupont wires on a breadboard besides the Arduino are not really an interface which could drive your Synth, Sequencer, or Drum machine over a 5m long MIDI cable.

Note: If your HMI project was developed via 0.53 or prior version Nextion Editor, we recommend you to use the LTS version for project maintenance as the latest version is not fully compatible with your exsisting source code and GUI desgin.

Two 4-pin XH connectors for 5V power supply, TX, RX and GND allow this interface to be easily daisy-chained between either a power supply / USB to TTL serial adapter like the Nextion Foca Max, or any MCU (Arduino, etc.) on one side (J1) and a Nextion HMI display on the other side (J2). The on-board switch SW1 allows to select between 2 modes:

The Nextion Micro SD card extender helps you to access the SD card slot of the Nextion HMI display more conveniently. It supports the FAT32 Micro SD card as well as all series of Nextion HMI displays compatibilities.

Note: as for the Nextion HMI display size less than 4.3”, you can only use the USB for power supply, size large than 4.3”, a external DC 8-26V for power supply is recommended.

Nextion Editor is a free human-machine interface (HMI) GUI development software for Nextion Basic Series, Discovery Series, Enhanced Series, and Intelligent Series. The software offers an easy way to create an intuitive and superb touch user interface even for beginners. Add a static picture as a background, define functions by components, you can make a simple GUI in minutes. The easy Drag-and-Drop components and simple ASCll text-based instructions will dramatically reduce your HMI project development workloads and develop projects rapidly in a cost-effective way. The Nextion product is the best balance HMI solution between cost and benefit with a low and decreased learning curve.

Debug the HMI project at any time even without the Nextion Display. The instruction input area allows you to send any Nextion commands to check the feedback and interactions.
