Limitations of Go language: not suitable for embedded development
Go 语言不适用于嵌入式开发,原因如下:内存消耗高:Go 的垃圾收集器需要额外内存,不适合内存有限的嵌入式设备。实时性差:垃圾收集器和并发模型可能引入不可接受的延迟,不适合时间敏感的嵌入式系统。代码大小大:Go 生成的二进制文件比其他语言(如 C 或 C++)大,对于受限设备来说不可行。
Go 语言的局限性:不适用于嵌入式开发
Go 语言是一个功能强大的现代编程语言,但在某些领域存在局限性,其中一个主要局限性就是不适用于嵌入式开发。嵌入式开发涉及为微控制器、传感器等受限设备创建软件。
内存限制
Go 语言通常比其他语言消耗更多内存,这使其不适合内存有限的嵌入式设备。这种开销主要是由于 Go 的垃圾收集器,它在执行时需要额外的内存来管理内存分配。
实时性
嵌入式系统通常需要对时间敏感的应用程序,而 Go 语言的垃圾收集器可能引入延迟,这在实时系统中是不可接受的。此外,Go 语言的并发模型可能难以预测,这可能会导致任务超时或不必要的上下文切换。
代码大小
Go 生成的二进制文件通常比使用其他语言(如 C 或 C++)生成的二进制文件要大。这对于内存受限的嵌入式设备来说可能是不可行的,需要将尽可能多的代码塞进有限的空间中。
实战案例
在实践中,不适用于嵌入式开发的 Go 语言可以很好地说明其局限性。考虑一个简单的情景,我们要使用 Go 为 Arduino 微控制器编写一个闪烁 LED 的程序。
package main import ( "machine" "time" ) func main() { // 获取 LED 引脚 led := machine.LED // 创建一个循环以闪烁 LED for { led.High() time.Sleep(1000 * time.Millisecond) led.Low() time.Sleep(1000 * time.Millisecond) } }
这个程序编译后的二进制文件大小为 1.5 MB,这对 Arduino Uno 等受限设备来说太大。此外,垃圾收集器的开销可能会导致闪烁行为不一致,这在时间敏感应用中是不可接受的。
结论
虽然 Go 语言在许多领域是一个强大的选择,但它并不适合嵌入式开发。其内存消耗、延迟不确定性和代码大小问题使其不适合资源受限的设备。其他更合适的嵌入式开发语言包括 C、C++ 和 Rust。

In C, the char type is used in strings: 1. Store a single character; 2. Use an array to represent a string and end with a null terminator; 3. Operate through a string operation function; 4. Read or output a string from the keyboard.

The calculation of C35 is essentially combinatorial mathematics, representing the number of combinations selected from 3 of 5 elements. The calculation formula is C53 = 5! / (3! * 2!), which can be directly calculated by loops to improve efficiency and avoid overflow. In addition, understanding the nature of combinations and mastering efficient calculation methods is crucial to solving many problems in the fields of probability statistics, cryptography, algorithm design, etc.

Multithreading in the language can greatly improve program efficiency. There are four main ways to implement multithreading in C language: Create independent processes: Create multiple independently running processes, each process has its own memory space. Pseudo-multithreading: Create multiple execution streams in a process that share the same memory space and execute alternately. Multi-threaded library: Use multi-threaded libraries such as pthreads to create and manage threads, providing rich thread operation functions. Coroutine: A lightweight multi-threaded implementation that divides tasks into small subtasks and executes them in turn.

std::unique removes adjacent duplicate elements in the container and moves them to the end, returning an iterator pointing to the first duplicate element. std::distance calculates the distance between two iterators, that is, the number of elements they point to. These two functions are useful for optimizing code and improving efficiency, but there are also some pitfalls to be paid attention to, such as: std::unique only deals with adjacent duplicate elements. std::distance is less efficient when dealing with non-random access iterators. By mastering these features and best practices, you can fully utilize the power of these two functions.

The release_semaphore function in C is used to release the obtained semaphore so that other threads or processes can access shared resources. It increases the semaphore count by 1, allowing the blocking thread to continue execution.
