April 4th, 2024 Update News

With the newer version of Pi-Star and WPSD, they broke my EDDC driver in displaying user information. This happened because they re-organized the mmdvmhost settings file. Each version has the mmdvmhost settings information in a different order. This problem has been corrected in the 240401 version of the EDDC NextionDriver just released.

April 2nd, 2024 Update News

The scripts have been updated to handle the new mmdvm HotSpot images from WPSD and Pi-Star. As things develop here, I'll be making more updates and changes. There are MAJOR EDDC NextionDriver execuatble updates in the works. ALSO, the Nextion Code Version B will be modified to handle the changes to the EDDC NextionDriver. AS ALWAYS, ENJOY!

Amateur Radio Nextion Displays


About These Offerings

As I always tell everyone, I'm Visually Impaired / Legally Blind, these projects are extremely complex, and, I'm not perfect by no means, I even fail myself. IF you think you found a mistake, PLEASE let me know. When WE fix something together, WE fix it for everyone!
42 NDCVerA and 42 NDCverB different versions for the Nextion Display are offered here. I provide for Display Type Nextion Basic, Discovery, Enhanced, or Intelligent. The Sizes are 2.4", 2.8", 3.2", 3.5", 4.3", 5.0", 7.0", or 10.1" and the Landscape Orientation for the Display Power/Control Wires to be on the Left or the Right.
These Nextion Display Code files were/are designed by/for the visually impaired (like myself) and the blind with display readers. IF your looking for a flashy trickery type of screens, then these are NOT for you. These Nextion Display Screens are meant to display stable information for a period of time for special readers (used by the blind) to have the time to read them.
There is no charge for using this website. There is no Website ads. There is no links asking for money. There is no links asking for your help. AND, I don't require anyone to kneel before me and kiss my ring (HA! Sorry No Ring!). The "Keys To The MMDVM Nextion Kingdoms" is below. Everything here is a work in progress, this when my disabilities cooperate with my abilities.
Please take the time to ENJOY the FRUITS of my HOBBIES, Amateur Radio.

The History Behind These Screens

Keep It Simple Screens for Nextion Displays, or KISS/ND, was born out of necessity. My eyesight is not good, I'm legally blind. Trying to watch the screen on the handheld for contact info was not good and the screens that came on my HRO hotspots, 2.4", wasn't built for poor eyesight either.
When I asked around about it, I was told that if I didn't like it, Program One Yourself! Well, though this was said to me in a sarcastic way, thus meaning I guess that I wasn't up to the challenge. So, instead of sounding like I was complaining, I decided to program my own screens for my hotspot that I could see better. And so, the AG4OJ Nextion Display Screens were born.
When another Amateur Radio Operator heard that I was making my own screens, they wanted to try them. This is turn gave birth to creating even more types, sizes, and orientations. This then spread word of mouth and suddenly I needed a place to host them, this Website was born. I then gave in to requests for more Nextion Basic versions, and this grew even more.
This Website has become a looking place not just for visually impaired screens, it has become a place to look for all screen types, sizes, and landscape orientations for Amateur Radio Hotspots / Repeaters. So, over the August / September 2019 time frame, a version was put together for every display type, size, and landscape orientation.
In mid 2020, legal challenges came to roost. Though these were not warranted, the individuals involved soon learned what it means to really be sued. I guess they didn't think I had the resources to respond to such. This is why these Nextion Display Code files were off-line for 6 months. Late December 2020, with requests coming in for updates, these files returned as a public offering.
In January 2021, a group of AROs asked me if I would take on making the Nextion Driver go to the next level. I took a look at it and this started my beginning steps into programming in C. The first step was to have a working Screen Saver. It has grown from there, and, with the ever maturing Nextion Display Code, Well, all can say is, like I always do, ENJOY!
As Always, ENJOY! It's A hobby, NOT A JOB! HA!
AND, Make Sure You Always PAY IT FORWARD!
