Today I will share an article on the microcontroller program framework. 1. The importance of program framework Many people, especially beginners, often want to write bit by bit when writing code. They don’t have an overall plan at the beginning, which leads to more and more messy code later and constant bugs. In the end, […]

GO Qianlian – pointers, structs, arrays, slices and mappings
Pointer What is a pointer? Go has pointers, a pointer variable pointing to the memory address of a value. For example: type *T is a pointer to a value of type T. Its zero value is nil. The pointer declaration format is as follows: var var_name *var-type var p*int & amp; operator The & amp; […]
Array and Slice in go language
Some languages use arrays as commonly used basic data structures, such as JavaScript. However, arrays in Golang tend to be positioned as an underlying data structure, recording a continuous piece of memory space data. However, in the Go language, we rarely use arrays directly. In most scenarios, we will directly use the more flexible slice […]
Go data structures – arrays, slices and maps
Go data structures-arrays, slices and maps Created: October 14, 2023 2:44 PM Class: Golang Type: master Reviewed: No There are three data structures in the Go language that allow users to manage collection data: arrays, slices, and maps. These three data structures are part of the core of the Go language and are widely used […]

Go language arrays and slices
Array An array is a collection of elements of the same type. For example, the set of integers 5, 8, 9, 79, 76 forms an array. Mixing values of different types, such as arrays containing both strings and integers, is not allowed in Go. Statement Arrays are of type [n]T. n represents the number of […]
Understand Array and Slice in Go
Introduction In Go, Arrays and Slices are data structures composed of ordered sequences of elements. These datasets are ideal for use when many related values need to be processed. They allow you to keep data together where it should be, compress code, and perform the same methods and operations on multiple values at once. Although […]

uCOSIII real-time operating system 5 task API (time slice rotation API scheduling)
Time slice rotation scheduling Time slice rotation method: mainly used for process scheduling in time-sharing systems. In order to implement round-robin scheduling, the system arranges all ready processes into the first process of a queue according to the first-in, first-out principle, and allows the CPU to run for a time slice. A time slice is […]
[Python 4] List and tuple slice slice iteration list generation generator generator iterator iterator object
L = [] n=1 while n < 100: L.append(n) n = n + 2 In Python, more code is not better, but less is better Taking some elements of a list or tuple is a very common operation. L = [‘Michael’, ‘Sarah’, ‘Tracy’, ‘Bob’, ‘Jack’] r = [] n=3 for i in range(n): r.append(L[i]) r […]
