Understanding Berry Script Language for 32-bit Microcontrollers
Berry is a scripting language designed specifically for 32-bit microcontrollers. It is a powerful tool that enhances the development capabilities of these devices. In this article, we will delve into the details of Berry, exploring its features, syntax, and how it can be integrated into your projects.
Basic Types Supported by Berry
Berry supports a variety of basic types, including nil, integer, real, boolean, string, class, list, map, range, and func. These types are essential for building complex applications on your microcontroller. Here’s a brief overview of each type:
| Type | Description |
|---|---|
| nil | Represents an empty type, often used as a placeholder or to indicate the absence of a value. |
| integer | Used for whole numbers, such as 1, 2, 3, etc. |
| real | Used for decimal numbers, such as 1.5, 2.75, etc. |
| boolean | Represents true or false values, often used in conditional statements. |
| string | Used for text, enclosed in single or double quotes. |
| class | Used to create objects and provide object-oriented support. |
| list | A variable-length array, allowing you to store and manipulate collections of values. |
| map | A hash table, enabling you to store and retrieve values based on keys. |
| range | Represents an integer interval, such as 1 to 10. |
| func | Used to define functions, allowing you to encapsulate and reuse code. |
Integration with C Language
Berry is designed to be easily integrated with C language. You can call Berry code from C, and vice versa. This allows you to leverage the strengths of both languages in your projects. For example, you can use Berry for high-level scripting tasks, while relying on C for performance-critical sections of your code.
Control Structures and Functions
Berry provides a variety of control structures and functions to help you manage your code. These include:
-
Assignment operators
-
Relational operators
-
Logical operators
-
Arithmetic operators
-
Bitwise operators
-
Field operators
-
Indexing operators
-
String concatenation operators
-
Conditional operators
-
Brackets
-
Control structures, such as condition statements, iteration statements, and jump statements
Local Variables and Scope
Berry supports local variables and block scope, allowing you to manage your code effectively. Local variables are declared within a function and are only accessible within that function’s scope. This helps prevent naming conflicts and makes your code more readable.
Functions and Nested Function Definitions
Berry allows you to define functions, which can be nested within other functions. This feature is particularly useful for organizing your code and creating reusable components. You can also define anonymous functions, also known as lambda expressions, which can be used to create concise and readable code.
Classes and Inheritance
Berry supports classes, which provide object-oriented support. You can define classes with methods and operators, and even create subclasses by using inheritance. This allows you to create complex and modular applications on your microcontroller.
