Understanding the Relationship Between Micro:bit and Arduino

The Emergence of Arduino

Many people may have heard of Arduino before Micro:bit, or even used Arduino.

Before the advent of Micro:bit, Arduino was hailed as the most suitable circuit board for maker education, as we can see that many maker product manufacturers use the Arduino UNO's 328P chip as their main control chip. In fact, if we consider cost-effectiveness, the 328P is not the most cost-effective chip, but it is the most suitable

Implementing Neural Networks on a 10-Cent RISC-V MCU Without a Multiplier

For some time now, I have been contemplating setting up an environment to implement algorithms based on neural networks on a smaller (8-pin) microcontroller. After reviewing existing solutions, I found that none truly satisfied me. An obvious problem is that flexibility often comes at the cost of overhead. As usual, for a truly optimized solution, you have to roll it out yourself.

How Highly Integrated Embedded Processors Drive the Development of Industrial Robots

Click the blue text above
Follow us!
With the advancement of semiconductor technology and the growing demand for smarter, safer, and more efficient systems, industrial robots have undergone significant transformations in recent years. At the core of this transformation is the use of advanced embedded processors that adopt a system-on-chip (SoC) architecture, integrating various components including peripherals and hardware accelerators. These processors play a crucial role in enhancing the capabilities

Comprehensive Review of the NUCLEO-F446ZE Development Board: Compatibility and Performance Enhancement

In December of last year, I learned that STMicroelectronics (ST) expanded its low-cost evaluation board Nucleo series, launching the Nucleo 144 series evaluation board based on Nucleo 64 and Nucleo 32. After a few months of waiting, I finally got to see it!
Thanks to the EEWORLD community and the administrators for giving me the opportunity to evaluate a NUCLEO-F446ZE evaluation board. Today, let’s experience the new favorite of Nucleo together.
My review will include:
1. Unboxing
2. Powering on
3. Overview
4. Development
5. Summary

Light Up an LED: Programming NodeMCU with Arduino IDE

Previously, we introduced "ESP8266 and the IoT magic tool NodeMCU", many friends expressed interest but felt that the author did not mention any practical content. Since this is the case, the author will periodically release some tutorials on this IoT learning tool, NodeMCU.
The Origin of NodeMCU
In "ESP8266 and the IoT magic tool NodeMCU", we talked about how before

Comprehensive Comparison of Common Embedded Processors

EmbeddedProcessor Overview
Embedded processors are the core of embedded systems, serving as the hardware unit that controls and assists system operation. The range is extremely broad, from the initial 4-bit processors, the still widely used 8-bit microcontrollers, to the latest 32-bit and 64-bit embedded CPUs that are widely favored.
Since the advent of microprocessors, embedded systems have developed rapidly, and embedded processors are undoubtedly the core part of embedded systems, directly affecting the performance of the entire embedded system. Typically, embedded processors
