The Allwinner T527 features rich interface resources, easily meeting application scenarios such as smart commercial displays, intelligent cockpits, and industrial control. To assist users in better developing on the T527 development board, Mil Electronics has released a wealth of software and hardware documentation, detailing the core functions and publicly available materials regarding the MEasy HMI 2.0 framework, RT-Linux real-time patch, and kernel drivers.
The MIFANS Pi TINA5.0 (Linux 5.15) system is an image built with buildroot featuring a QT5.12 interface, including complete hardware drivers, commonly used system tools, debugging tools, etc., along with GUI runtime libraries and HMI interfaces. It supports application development using Shell, C/C++, QML, and Python.

1.MEasy HMI 2.0 Framework
MEasy HMI 2.0 is a human-machine interface framework developed by Shenzhen Mil Technology Co., Ltd. based on QT5. The project adopts a mix of QML and C++ programming, using QML to efficiently and conveniently build the UI, whileC++ is used to implement business logic and complex algorithms. Depending on the type of application, we classify the entire UI into five major categories: multimedia, smart home appliances, healthcare, public services, and systems. Each category contains different subcategories, for which we implement corresponding applications. As shown in Figure 1.

2.RT-Linux Real-Time Patch Effect Testing
cyclictest -t4 -p 80 -i 10000 -l 10000
Test results are as follows:
stress-ng --sock 36 --taskset 0,1,2,3,4,5,6,7 --timeout 120h & stress-ng -c 36 --taskset 0,1,2,3,4,5,6,7 --timeout 120h &
cyclictest -t4 -p 80 -i 10000 -l 10000
Test results are as follows:
cyclictest -t20 -p 80 -i 10000 -l 10000
