1.简介
- 大脚蟹是一个面向嵌入式单片机系统的虚拟机平台，它可以让开发者抛开繁锁的硬件底层开发，从而使用简单易用的开发方式，专心开发他自己的应用程序。另一方面，也可以让硬件生产商在开发模式的时候，仅需提供硬件驱动接口，避免让核心硬件驱动直接暴露在初学者面前，从而保护硬件驱动的稳定性。
2.特点
- 软硬件分离，让前端软件工程师专注应用程序的开发。
- 专用硬件API接口，让应用程序控制硬件不再困难。
- 兼容C#/Java大部分语法，大大降低语言学习难度。
- 应用程序和硬件驱动程序物理隔离，不但彻底保护硬件驱动程序，更可以使用加密的方式保护应用程序。
- 提供一整套开发过程中所必须的东西，它包括语言编译器，用户程序下载器，硬件日志监控，PC端虚拟设备，虚拟机。
3.用户端开发语言 大脚蟹的用户端开发语言采用CRAB语法，它有以下特点
- 兼容大部分的 C# / Java 语法。
- 关键字和标识符不区分大小写。
- 字符串很方便使用，并且支持多种写法。
- 独有的日期时间格式。
- 有专用的接口和格式，用于软硬件沟通。
- 独有的事件函数。
- IF 语法和 Switch/Case 语法 更加强大好用。
- 支持类(Class)和属性(Property)，使用方便。
- 还有其它加快开发的特性。。。
4.虚拟机实现端的开发语言
- 是Ansi C，目前在BCB和IAR上编译通过，并运行完好。

1.Introduction
- CRAB is a virtual machine platform for embedded microcontroller systems that allows developers to deviate from the underlying hardware development, using an easy-to-use development approach to develop their own applications. On the other hand, you can also let the hardware manufacturer in the development mode, only need to provide hardware-driven interface, to avoid the core hardware drivers directly exposed to the beginners in front, thus protecting the stability of hardware-driven.
- Features
- Hardware and software separation, so that front-end software engineers focus on the development of applications.
- Dedicated hardware API interface, so that the application control hardware is no longer difficult.
- Compatible with C # / Java most of the syntax, greatly reducing the difficulty of language learning.
- Physical isolation of applications and hardware drivers, not only to completely protect the hardware drivers, but also can use encryption to protect the application.
- Provide a set of necessary things in the development process, which includes language compiler, user program downloader, hardware log monitoring, PC-side virtual devices, virtual machines.
- Client development language client development language using CRAB syntax, it has the following characteristics
- Compatible with most of the C # / Java syntax.
- Keywords and identifiers are not case sensitive.
- Strings are easy to use and support multiple wordings.
- Unique date and time format.
- There are dedicated interfaces and formats for hardware and software communication.
- Unique event function.
- IF syntax and Switch / Case syntax is more powerful and easy to use.
- Support class (Class) and property (Property), easy to use.
- There are other features that accelerate development.
- Virtual machine to achieve the development language
- Is Ansi C, currently compiled on BCB and IAR, and is running well.
