Core competitiveness of products
Learning cycle: 30 minutes to familiarize yourself with the development environment, 3 days to complete human-computer interaction design.
Program debugging: The host computer integrates a "virtual serial port screen," eliminating the need for hardware connection and allowing direct Keil debugging. IDE-bound debugging
Startup Time: Runs instantly upon power-up, eliminating system loading time
Configuration Controls: Features a variety of configuration controls, including multi-language controls, buttons, text, drop-down menus, progress bars, sliders, meters, animations, QR codes, curves, data loggers, circular progress bars, and sub-screen slide controls.
System Keyboard: Built-in virtual numeric and character keyboards, supporting Chinese and English input methods, and customizable keyboards.
Data Logging: Supports exporting data logger content to an SD card.
Layer Technology: Multiple display layers are built into the system for faster switching.
Multilingual Capability: Factory-preset up to 15 global languages, enabling one-click switching without the need for multiple UIs.
Logical Operation Processing: The host computer has an embedded LUA script parser, allowing users to customize complex logic relationships and protocols within the screen, meeting 99.9% of customer product requirements.
Remote Upgrade: Supports remote serial port upgrades of display firmware, project files, specified images, configuration files, and fonts.
Lifecycle: Utilizes a traditional, leading-edge processor, ensuring long-term supply.
