DIY Projects for Tech Enthusiasts: Lights and Music

Your Infinity Gauntlet is just missing a little something to snap your fingers.

Where there is creation, there are tech enthusiasts;

Where there are tech enthusiasts, there is the DF Maker Community;

As a community editor who shares valuable content every day,

I’ve seen thousands of projects!

But!

So what…

I still can’t figure out what you tech enthusiasts like…

Pfft…

Because I accidentally discovered

that what tech enthusiasts are most passionate about making

is actually lights and music!

These two words

Evaluating the Inclusion of Loongson, Shenwei, and Phytium CPUs in Central Government Procurement List

Recently, the announcement of the 2018-2019 procurement project for information products (hardware) and air conditioning products by central state organs showed that the CPUs of Loongson, Shenwei, and Phytium have been included in the central government procurement list. Previously, although the CPUs of Loongson, Phytium, and Shenwei had been subject to local pilot projects, they had not been included in the central government procurement list. This event indicates the state’s emphasis on Loongson, Phytium, and Shenwei, as well as recognition

How to Use MCC Data Acquisition Cards with Raspberry Pi

Editor’s note: Data acquisition solutions used in industry are generally based on Windows systems, but as Raspberry Pi is increasingly applied in the industrial field, products and applications based on Raspberry Pi have finally appeared in the data acquisition field. We previously introduced two data acquisition expansion boards suitable for Raspberry Pi, the MCC118 and MCC152, which greatly reduce the application cost of data acquisition solutions. What we will introduce next is how to install and use the MCC data

Protecting Structures in Embedded C

    Follow and star our public account for exciting content









Are you confused by the implementation of macros or their usage? The essence of the mask structure macro is to use a mask array chMask to protect the structure.
You can refer to the PLOOC usage examples from senior developers and its object-oriented programming based on C language in the document "Silly Child.pdf" (reply with: Object-oriented programming based on C language in our public account chat interface)

						Mastering FreeRTOS: A Comprehensive Guide to Doubly Linked Lists
					
				
			
							
								
					
					Abstract: Today, we will discuss the doubly linked list by combining the source code of FreeRTOS's linked list. Note: A linked list item is a node, and a node is a linked list item; they refer to the same thing, and it doesn't matter what you call it.
1. Defining the Linked List Structure
// Define the linked list, which is also the head of the linked list
typedef struct xLIST
