Raspberry Pi 5: Engineer Perspectives on the Latest Release
It has been 4 years since the release of the previous generation of Raspberry Pi (RPI4 @2019). The Raspberry Pi 4 even reached a "sky-high price" for a while, becoming a financial product, and there was news earlier this year that there would be no updates.
However, the Raspberry Pi has officially announced the information for the fifth generation and is set to be released on October 23. Although the overall
Exploring FPGA Projects in International Universities
Let's take a look at FPGA development projects at international universities.
As far as I know, many universities in China do not offer courses related to FPGA, so many students are self-taught. However, self-learning requires certain goals and projects. Today, let's look at the FPGA project courses offered by Cornell University, an Ivy League school. Most of the courses come with source code, and they are developed in Verilog, similar to the practices in
Understanding ADC Quantization Error in Embedded Systems
01 ADC Quantization Error
1. Introduction
AD\Test\2024\April\TestATMEGA16.SchDoc
Recently, the sampling characteristics of a 10-bit ADC were measured. When the input signal changes very slightly, the quantization error of the ADC greatly affects the sampling results. Even averaging 512 data points cannot eliminate the impact of quantization error. Next, tests were conducted by introducing noise interference into the signal to mitigate the errors caused by quantization. Oversampling the data and averaging it can improve the ADC's resolution.

Understanding Why MCUs Typically Run RTOS While SoCs Often Run Embedded Linux
This article is very popular: Differences between CPU, SoC, and MCU
MCU (Microcontroller Unit) and SoC (System on a Chip) are two different types of embedded systems that typically run different types of operating systems, depending on their application scenarios and hardware resources.
MCU (Microcontroller Unit):
Type: An MCU is a microcontroller that integrates a processor core, memory, peripherals, and other basic functions on a single chip.
Application Scenarios: Commonly used in simple, real-time embedded systems, such as sensor control, embedded devices, etc.
Operating System:
