The Express Logic and Azure RTOS Ecosystem

A Brief History

GUIX's lineage is deeply tied to Express Logic and its ThreadX RTOS. The author of ThreadX, William Lamie (also the original author of the Nucleus RTOS released in 1990), founded Express Logic in 1996. The first version of ThreadX RTOS was released in 1997. Over the years, Express Logic expanded the ThreadX ecosystem with a suite of high-reliability middleware:

  • FileX: The embedded file system was first released in 1999.
  • NetX: The embedded TCP/IP networking stack debuted in 2002.
  • USBX: The embedded USB host/device stack followed in 2004.
  • GUIX: The embedded UI component, the focus of this article, was first released in 2014.

A significant milestone occurred on April 18, 2019, when Microsoft acquired Express Logic, integrating its technologies into the Azure IoT and edge computing portfolio under the Azure RTOS brand. This move underscored the industrial strength and strategic importance of these components.

GUIX 的血统与 Express Logic 及其 ThreadX RTOS 紧密相连。ThreadX 的作者 William Lamie(也是 1990 年发布的 Nucleus RTOS 的原创作者)于 1996 年创立了 Express Logic。ThreadX RTOS 的第一个版本于 1997 年发布。多年来,Express Logic 通过一套高可靠性中间件扩展了 ThreadX 生态系统:

  • FileX:嵌入式文件系统于 1999 年首次发布。
  • NetX:嵌入式 TCP/IP 网络协议栈于 2002 年首次亮相。
  • USBX:嵌入式 USB 主机/设备协议栈于 2004 年发布。
  • GUIX:本文重点关注的嵌入式 UI 组件于 2014 年首次发布。

一个重要的里程碑发生在 2019 年 4 月 18 日,微软收购了 Express Logic,将其技术整合到 Azure RTOS 品牌下的 Azure IoT 和边缘计算产品组合中。此举凸显了这些组件的工业实力和战略重要性。

Unmatched Safety Certification Portfolio

A defining characteristic of the Azure RTOS suite, including GUIX, is its unparalleled set of safety certifications. These certifications are not merely checkboxes; they represent a massive investment in rigorous development processes, testing, and third-party validation, making these components uniquely qualified for safety-critical applications. The certifications held by GUIX include:

  • Medical: IEC-62304 Class C
  • Automotive: IEC-61508 ASIL D
  • Industrial: IEC-61508 SIL 4
  • Transport/Railway: EN50128

This broad certification spectrum indicates that GUIX is engineered from the ground up for environments where failure is not an option.

Azure RTOS 套件(包括 GUIX)的一个决定性特征是其无与伦比的安全认证组合。这些认证不仅仅是勾选框;它们代表了在严格的开发流程、测试和第三方验证方面的巨大投入,使得这些组件在安全关键型应用中具有独特的资格。GUIX 持有的认证包括:

  • 医疗:IEC-62304 Class C
  • 汽车:IEC-61508 ASIL D
  • 工业:IEC-61508 SIL 4
  • 运输/铁路:EN50128

这种广泛的认证范围表明,GUIX 是从头开始为不允许失败的环境而设计的。

Deep Dive into Azure RTOS GUIX

Core Architecture and Features

GUIX is a full-featured, event-driven GUI framework written entirely in C for optimal performance and portability. Its architecture is designed to be both powerful and efficient.

GUIX 是一个功能齐全、事件驱动的 GUI 框架,完全用 C 语言编写,以实现最佳性能和可移植性。其架构设计既强大又高效。

1. Consistent API Design

GUIX employs an intuitive Noun-Verb naming convention. All API functions are prefixed with gx_ for easy identification. For example, gx_widget_front_move breaks down as: prefix gx, noun widget_front_, verb move. This consistency makes the API predictable and easier to learn and use.

GUIX 采用直观的 名词-动词命名约定。所有 API 函数都以 gx_ 为前缀,便于识别。例如,gx_widget_front_move 可以分解为:前缀 gx,名词 widget_front_,动词 move。这种一致性使 API 可预测,更易于学习和使用。

2. Rich Widget Library

GUIX provides a comprehensive set of pre-defined, yet fully customizable widgets. The library is compact and efficient, including:

  • Basic Controls (Button, Checkbox, Radio Button, Slider, Progress Bar)
  • Text Elements (Prompt, Single/Multi-Line Text Input/View)
  • Advanced Controls (Drop-down List, Scroll Wheel, Horizontal/Vertical List, Circular Gauge, Line Chart, Tree View)
  • Containers (Window, Accordion Menu)
    Users can also create custom widgets to meet specific application needs.

GUIX 提供了一套全面、预定义且完全可定制的小部件库。该库小巧高效,包括:

  • 基本控件(按钮、复选框、单选按钮、滑块、进度条)
  • 文本元素(提示框、单行/多行文本输入/视图)
  • 高级控件(下拉列表、滚动轮、水平/垂直列表、圆形仪表、折线图、树形视图)
  • 容器(窗口、手风琴菜单)
    用户还可以创建自定义小部件以满足特定的应用需求。

3. Powerful Canvas Drawing API

For custom graphics, GUIX offers a low-level canvas drawing API that supports complex shapes with features like anti-aliasing (for high color depth) and alpha blending. Functions include:

  • gx_canvas_line_draw (直线绘制)
  • gx_canvas_circle_draw (圆形绘制)
  • gx_canvas_arc_draw (圆弧绘制)
  • gx_canvas_polygon_draw (多边形绘制)
  • gx_canvas_pixelmap_rotate (像素图旋转)
  • gx_canvas_text_draw (文本绘制)
    Shapes can be outlined or filled with solid colors or pixelmap patterns.

对于自定义图形,GUIX 提供了一个低层级的画布绘图 API,支持复杂形状,并具有抗锯齿(适用于高色深)和 Alpha 混合等功能。函数包括:

  • gx_canvas_line_draw
  • gx_canvas_circle_draw
  • gx_canvas_arc_draw
  • gx_canvas_polygon_draw
  • gx_canvas_pixelmap_rotate
  • gx_canvas_text_draw
    形状可以勾勒轮廓或用纯色或像素图案填充。

4. Event-Driven Model

GUIX follows a pure event-driven programming model, which is ideal for UI design. The GUIX thread automatically suspends when idle, saving CPU cycles. Events from input devices (touch, keys) are placed into a queue and processed accordingly. This model cleanly isolates device drivers from the GUI drawing tasks.

GUIX 遵循纯粹的事件驱动编程模型,非常适合 UI 设计。GUIX 线程在空闲时会自动挂起,以节省 CPU 周期。来自输入设备(触摸屏、按键)的事件被放入队列并进行相应处理。这种模型清晰地将设备驱动程序与 GUI 绘图任务隔离开来。

5. Resource and Memory Efficiency

GUIX is designed for resource-constrained environments. Its memory footprint is remarkably small:

  • Minimum Flash: ~13.2 KB (without canvas support on self-refresh displays)
  • Minimum RAM: ~4 KB
    When a canvas is required, its RAM size is calculated as: Canvas RAM (bytes) = width * height * (bits_per_pixel / 8). Additional memory is needed for graphics resources and fonts, which depends on the application.

GUIX 专为资源受限的环境而设计。其内存占用非常小:

  • 最小 Flash:约 13.2 KB(在支持自刷新的显示屏上无需画布时)
  • 最小 RAM:约 4 KB
    当需要画布时,其 RAM 大小计算公式为:画布 RAM (字节) = 宽度 * 高度 * (每像素位数 / 8)。图形资源和字库需要额外的内存,这取决于具体应用。

6. Broad Hardware Support

GUIX is highly portable. It supports a wide range of:

  • Color Formats: From monochrome (1-bit) to 32-bit ARGB.
  • Input Devices: Resistive/Capacitive touchscreens and physical keyboards.
  • Display Drivers: Any LCD that can be driven at the bare-metal level can be adapted for GUIX, given the minimum RAM/Flash requirements are met. It also supports multi-display setups.

GUIX 具有高度的可移植性。它支持广泛的:

  • 颜色格式:从单色(1 位)到 32 位 ARGB。
  • 输入设备:电阻/电容式触摸屏和物理键盘。
  • 显示驱动:任何可以在裸机层面驱动的 LCD,只要满足最小 RAM/Flash 要求,都可以适配 GUIX。它还支持多显示设置。

GUIX Studio: The Design Powerhouse

GUIX Studio is the Windows-based desktop design tool that dramatically simplifies GUI development. It allows designers and engineers to visually create interfaces, define screens, place widgets, set properties, and configure themes.

GUIX Studio 是基于 Windows 的桌面设计工具,极大地简化了 GUI 开发。它允许设计师和工程师可视化地创建界面、定义屏幕、放置小部件、设置属性和配置主题。

Key Workflow and Benefits:

  1. Visual Design: Create the GUI layout WYSIWYG (所见即所得).
  2. Code Generation: GUIX Studio automatically generates ANSI C source and header files that represent the designed UI.
  3. Separation of Concerns: The generated code cleanly separates the UI design from the application logic. Developers can add custom event handling and drawing functions without modifying the auto-generated files.
  4. Resource Management: It packages fonts and images (PNG, JPEG) used in the design, handling format conversion and optimization for the target.
  5. Rapid Iteration: UI changes can be made in GUIX Studio and regenerated without affecting the core application code.

This workflow enables a collaborative process where UI/UX designers can create the visual aspect, and embedded engineers integrate it with system functionality.

关键工作流程和优势

  1. 可视化设计:以所见即所得的方式创建 GUI 布局。
  2. 代码生成GUIX Studio 自动生成代表所设计 UI 的 ANSI C 源文件和头文件。
  3. 关注点分离:生成的代码清晰地将 UI 设计与应用程序逻辑分离。开发人员可以添加自定义事件处理和绘图功能,而无需修改自动生成的文件。
  4. 资源管理:它打包设计中使用的字体和图像(PNG、JPEG),处理目标机的格式转换和优化。
  5. 快速迭代:可以在 GUIX Studio 中进行 UI 更改并重新生成代码,而不会影响核心应用程序代码。

这种工作流程支持协作过程,UI/UX 设计师可以创建视觉效果,嵌入式工程师将其与系统功能集成。
