Concept of DMA DMA (Direct Memory Access) allows data transfer without direct control from the CPU. It creates a direct pathway for data transfer between RAM and I/O devices, significantly improving CPU efficiency. There are several methods for UART data reception: the interrupt mode of UART isthe most commonly used data transmission method in microcontrollers, … Read more
Recently, I spent some time organizing the verification of the SPI module in the USI module of the WUJIAN100 project. Here, I would like to share some of my thoughts and methods. Basic Introduction to the Design Functionality of the USI Module USI (Unified Serial Interface) is a combined module that includes UART, SPI, and … Read more
Hug pid:131183771 by:White It is still discussed in the Microelectronic System Click here to view the Microelectronic System review: SPI The specific transmission details of SPI are clearly explained there, so I will briefly mention it here without going into detail. Overview SPI is a synchronous communication protocol developed by Motorola in the 1980s, primarily … Read more
With the rapid development of manufacturing processes, the complexity of miniaturized devices is increasing day by day. In cutting-edge industries such as microelectronics, medical technology, and photonics, micro-devices often adopt multilayer stacked structures made of different materials to meet increasingly complex multifunctional requirements. Especially in the healthcare sector, the application of Continuous Glucose Monitoring (CGM) … Read more
The relationship between the light absorption depth of silicon materials in image sensors and the wavelength of light can be explained by the physical mechanisms of photon energy and material interaction, as detailed below: 1. The Wave-Particle Duality of Light: Differences in Photon Energy Light exhibits wave-particle duality, and its energy formula is: E = … Read more
The Raspberry Pi 4B and STC8G microcontroller work together to create a new intelligent environmental monitoring system, easily achieving three main functions: displaying current video surveillance images and temperature and humidity data on a web page, and automatically saving recordings when an object enters the monitored area. How is this done? Let’s take a look … Read more
In the previous article discussing purple fringing in photography, we mentioned that one of the sources of purple fringing is highlight overflow, known as the Blooming phenomenon. Today, we will further elaborate on the Blooming phenomenon and the subsequent Smear phenomenon. 00 Preliminary Knowledge: Differences Between CCD and CMOS Before explaining these two phenomena, let’s … Read more
