Got it working with the UTFT library example, but it uses absolutely all I/O pins from an Arduino UNO (16 for data + 4 for control, just for image output, no SD, no touch sensing).

On the TFT"s PCB pins I connected Ground to Ground, Vcc to +3.3V, Led_A to +3.3V and the rest of the relevant TFT board pins (3.3V logic) THROUGH 10K RESISTORS to the Arduino Board pins (5V logic) with no problem.

I havent been able to find much for others with the similar problem with this setup. That along with >2000 of these screens being sold by the vendor makes me think I may have a non functioning unit.

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.First of all, let"s open a virtual bottle of Champaign - this is my 100st Sunday Blog post!!! Now, let"s celebrate this with a new functionality: Have your Nextion HMI computing square roots with just 21 lines of code and 5 integer variable components, everything nicely packed in a ready-to-use page template - the Nextion equivalent of a library as seen over the last weeks. The advantage is that you can add this function to a page by designing the latter by starting with importing the appropriate template and then customizing it as you would any other page of your project. And if your project doesn"t need it - let it away and save memory! In my humble opinion, that"s a way more interesting solution than requesting the integration of everything into the firmware, with all the runtime memory constraints.Did you ever see the need to increment or decrement values, for example on a settings screen? Did you want to avoid multiple clicks and would have preferred just keeping a button pressed while the value would continue to increment or decrement? And which would go at a higher speed when pressing the button for a longer time? After reading this article, you"ll know how to do that with your beloved Nextion HMI! And no, there is NO need to add to the event code of each button! Only 4 invisible components and less than 20 lines of code are required to transform all buttons on a page into repeater buttons. That is so compact that we"ll pack these into a single page template and export it. From then on, if you need buttons with accelerated auto-repeat on a page, go to the page pane, but instead of adding a blank page, import the template and you are done. Automatically, without an additional line of code, all buttons will magically have the repeat functionality!Two weeks ago, we discussed a few password security strategies. If you haven’t already, please read that before continuing. While all the basic mechanisms have been explained and code examples have been shown, using these in your own project might seem difficult since there are so many places where code snippets were to add.  Thinking about that latter aspect and how to ease the re-utilization, I suddenly had an inspiration: Why not follow the example of the keyboard system pages which are automatically added to your project when you link a text or number component to one of the built-in keyboard screens?
