Which is more powerful, Arduino or STM32? Many electronics enthusiasts face a dilemma when choosing between Arduino and STM32, unsure of which to use. Arduino has always been popular, but STM32 has more interfaces, stronger performance, and faster speeds?
Features of Arduino and STM32
Arduino:
Arduino leans towards creativity, simplifying hardware operations. Its functions and syntax are very simple and user-friendly.
First, let me clarify that MPU has many meanings, and there are two common ones:
MPU:Microprocessor Unit;
Additionally, some may associate it with modules like MPU-6050. So, please do not confuse MPU.
Why Use MPU?
If you develop embedded projects that suffer significant economic losses or major accidents due to memory overflow or memory faults, you will understand why a Memory Protection Unit (MPU) is necessary.
Using an MPU in embedded systems can help detect memory-related bugs early in development, saving more time.
Moreover,
In business, "must" represents the minimum requirements for market participation. Today, there are over a hundred open-source and commercial RTOS in the embedded market, most of which lack functional safety certification. Given this, it is clear that RTOS functional safety certification is not yet a "must" today, but perhaps it should be.
RTOS is the foundation of embedded devices, and all application code relies on RTOS for execution. RTOS is like the foundation of
32-bit ARM Cortex-M microcontrollers are widely used in various embedded systems and applications due to their low power consumption, high performance, and multifunctional features. These microcontrollers are utilized across a wide range of industries and applications.
Here are some common applications of 32-bit ARM Cortex-M microcontrollers:
IoT sensors and nodes
Home automation and smart devices
Industrial IoT (IIoT) devices
Wearable devices
Smartphones and tablets
Game consoles
Digital cameras
Smart TVs
1、reboot means to restart.
2、source makes the modified files take effect immediately, avoiding the problem of having to restart for the changes to take effect. For example, if we modify /etc/profile, the changes will not take effect immediately. In this case, we can enter source /etc/profile to apply the changes.
There will be more updates in the future.
3、chmod -R 777 /home/edu/practice sets all file permissions in the practice folder to 777.
4、Compress a single file: gzip

xTaskCreate(LED_Task, "LED_Task", 128, NULL, 6, NULL);If we want to elaborate on this question, there are many related knowledge points involved. Below are a few important related contents to answer this question.
Static and Dynamic Memory Allocation
Memory allocation is generally divided into: static and dynamic allocation.
1. Static
The embedded Bluetooth serial communication module allows us to break free from the constraints of cables and achieve wireless serial communication within a limited range, with two working modes: command response mode and automatic connection mode. In automatic connection mode, the module can be divided into three roles: Master, Slave, and Loopback. When the module is in automatic connection mode, it will automatically connect according to the pre-set data transmission method; when the module is

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.
// Define the linked list, which is also the head of the linked list
typedef struct xLIST
{
volatile unsigned int uxNumberOfItems;
