This post will show you an encrypted password input by full screen keyboard. This project is very timing consuming because it needs a lot of components to create. Download the HMI project file here
First of all, we need to create the encrypted password full screen input project in Nextion Editor. My idea is to make the password showed in one interface, by tapping the input box, we can jump to another interface which has a full screen keyboard. Therefore, we should create a project that contains two pages.
The pictures must be prepared ahead of time, you can search in the Internet and deal with them in Photoshop. Adjust the picture size according to your resolution.
Create a new HMI file. Then you can add the pictures inside picture library. Create your desired font and add to font library. And add two pages. There are multiple components to be added and set, and a lot of codes needed in this project. If you want to check the details, just download the HMI project file above and open it in Nextion Editor.
You can download the project file either from SD card or with a foca.
