1. Introduction The previous article discussed how to check process priority; this one explains how to set process priority. There are two methods for setting process priority: Command line; Source code; 2. Command Line Method main.c: #include <stdio.h> int main(int argc, char *argv[]) { while(1) { ; } return 0; } Compile: gcc -o proc-pri … Read more
(1) Process Concept A process is a program that has been executed. It does not occupy disk space but consumes system memory, CPU resources, and each running process corresponds to its own virtual address space. (2) Concepts of Parallelism and Concurrency The CPU allocates a time slice to each process, and a process can run … Read more
Implementing a DAC0832 to Output a Sawtooth Wave – Understanding Digital to Analog Conversion from Scratch Today we will implement an interesting case: using the DAC0832 to output a sawtooth wave. Through this case, not only will we learn the basic principles of DACs, but we will also master the methods for waveform generation. Introduction … Read more
Hello everyone, Rabbit Brother is back! Today we are going to learn a super practical communication method – SPI communication. It’s like a “highway” between Arduino and peripherals, allowing data transfer to be fast and stable. Whether dealing with SD cards, displays, or various sensor modules, SPI is a great tool. Let Rabbit Brother guide … Read more
1.What Is the Symbolic Math Toolbox? The Symbolic Math Toolbox is a functionality in Matlab for operations on symbolic objects. It introduces a special data type – symbolic objects; This data type includes symbolic numbers, symbolic variables, symbolic expressions, and symbolic functions, as well as symbolic matrices and symbolic arrays composed of the above variables, … Read more
This article introduces 19 commonly used components in MATLAB App Designer, including buttons, labels, axes, edit fields, radio button groups, toggle button groups, dropdowns, list boxes, checkboxes, trees, tables, sliders, spinners, state buttons, date pickers, text areas, images, hyperlinks, and HTML. There are a total of 21 commonly used components in MATLAB App Designer. Table … Read more
Private Functions A typical MATLAB installation contains hundreds of program files, which users can access simply by entering the file name. While this convenient access method is an advantage, it can also lead to clutter and name conflicts, especially due to the existence of some “helper functions” that are used by other functions but are … Read more
Previously, we discussed a lot about MATLAB vectors and matrices. In this chapter, we will discuss multidimensional arrays. In MATLAB, all variable data types are multidimensional arrays; a vector is a one-dimensional array, and a matrix is a two-dimensional array. First, let’s look at some special types of arrays. Special Arrays in MATLAB In MATLAB, … Read more
A reader asked how to package a MATLAB GUI into an executable EXE file, so I am sharing the method. The current MATLAB GUI uses files ending with .mlapp, rather than the old .fig based format. 1. Enter deploytool in the command window and press Enter, then select the first option. 2. Select the .mlapp … Read more
