Events

In the previous post, we brought our interface to life by enabling touch and responding to a button event. Now that we know how to capture user interactions, the next logical step is to make those interactions modify the interface itself. In this tutorial, we will build a slightly more complex and much more practical application: a digital counter. We will create a screen with a number and two buttons, one to increment and one to decrement that number. This example is fundamental because it teaches us how to read from and write to screen widgets, an essential skill for any UI project, whether it’s displaying sensor data, adjusting settings, or any other dynamic application. ...

In the previous posts, we prepared our environment, got the WT32-SC01 Plus screen working, and even displayed our first graphical interface created with SquareLine Studio. However, our screens were still static. It’s time to bring our project to life by enabling the board’s most important feature: the touch screen. In this tutorial, we will transform our static interface into an interactive application. Our goal is to add a button to the screen and, when it’s pressed, execute an action: printing a message to the Serial Monitor. This is the fundamental step for creating any complex application, from calculators to control panels. ...
