Hello everyone, I am Pi Zi Heng. Today, I will share the steps for quickly creating a new LCD screen example project using NXP’s GUI Guider. In my previous article, “How to Quickly Light Up a New LCD Screen on i.MXRT1170: Methods and Steps,” I introduced how to modify the official SDK bare-metal driver elcdif … Read more
GUI: Graphical User Interface. In the past, due to the limited resources and processing capabilities of MCUs, there were very few general GUIs based on MCUs. Now, with increased resources and stronger processing capabilities of MCUs, along with growing market demand, GUI functionalities have become richer. Let’s take a look at some common MCU-based GUIs. … Read more

Enable the multi-core functionality of the ESP32 to execute tasks in parallel while setting the chip’s clock frequency and the FreeRTOS real-time system. The effect achieved in this article is shown in the GIF, where two displays execute in parallel, each using one of the ESP32’s two cores. The display of the two screens, if … Read more
Using the LVGL GUI library with ESP32 allows for the implementation of modern and beautiful GUIs on microcontroller devices. This article is based on using the ESP32 with the Arduino framework to drive a 3.5-inch LCD screen. First, ensure that the TFT_eSPI can properly drive the 3.5-inch LCD screen. If the driver is not set … Read more
I am Lao Wen, an embedded engineer who loves learning. Follow me to become even better together! Engineers who have worked on embedded Linux system optimization know that when the system powers on, it first starts u-boot (sometimes with a u-boot wait delay). After u-boot boots the kernel, the kernel will load the driver, and … Read more
Previously, I wrote a few examples of how to use C# to write STM32 programs. Similarly, we can also use C# under ESP32, relying on the ever-growing .Net nanoFramework. Currently, it supports more and more development boards and chip types, and the related libraries are also increasing. The supported devices can fully support conventional application … Read more
There are many embedded GUI libraries available on the market, including open-source GUI libraries such as LVGL and EmWin, and closed-source GUI libraries like TouchGFX and Persimmon GUI. The testing board for this development tutorial comes from Tronlong Technology’s TLT113-EVM industrial evaluation board, which is based on the Allwinner Technology T113-i dual-core ARM Cortex-A7 + … Read more
