2. Software resources

MYD-YT527-SX provides abundant software resources to help customers realize product development as soon as possible. When the product is released, you can get all Linux BSP source code and abundant software development manuals.

It is worth mentioning that Mir has released the TINA5.0 system based on Linux for industrial applications (Ubuntu system will be supported in the future), which adds a lot of color to the Mi Pie T527, and users can carry out secondary development based on it.

MiFenPie's TINA5.0 system is an image based on buildroot with a QT5.12 interface, including complete hardware drivers, common system tools, debugging tools, etc., including GUI runtime library and HMI interface. It supports application development using Shell, C/C++, QML, and Python.

Mir Electronics has developed a human-machine interface framework based on QT5: MEasy HMI. The project uses QML and C++ mixed programming, using QML to efficiently and conveniently build UI, while C++ is used to implement business logic and complex algorithms.

The entire UI is divided into five categories according to the type of application: multimedia, smart home appliances, health care, public services, and systems. Each category contains different subcategories, and we have implemented corresponding applications for each subcategory, as shown in the figure:

Figure 2: MEasy HMI 2.0 block diagram

The MEasy HMI human-machine interface framework provides users with various interfaces and supports secondary development, which greatly facilitates rapid secondary development and saves development cycles.

Micro industrial computer T527

Next, I will introduce to you a micro industrial computer T527 launched by Mir. It is a mini IPC based on the Allwinner T527 domestic platform, compatible with Raspberry Pi and Amy Pi, supports software secondary development, and hardware white box.
