According to reports from Electronic Enthusiasts (by Zhou Kaiyang), as SSDs enter the PCIe 4.0 era, their read speeds have exceeded 7GB/s.Many users prioritize speed when purchasing SSDs, understanding that larger capacities generally lead to faster speeds, and they often choose chips like MLC. However, the SSD controller chip is equally important.If we compare an … Read more
The Serial Peripheral Interface (SPI) is one of the most widely used interfaces between microcontrollers and peripheral ICs (such as sensors, ADCs, DACs, shift registers, SRAM, etc.). SPI is a synchronous, full-duplex, master-slave interface. Data from the master or slave is synchronized on the rising or falling edge of the clock. Both the master and … Read more
Embedded C Language Development: Applications of C Language in Embedded Systems Introduction Embedded systems refer to systems that integrate computer technology into other devices to achieve specific functions. They are widely used in fields such as home appliances, automobiles, and medical devices. Due to its efficiency and flexibility, C language has become one of the … Read more
In the process of microcontroller programming, if a designer can master multiple programming languages simultaneously, then that designer is undoubtedly a very talented individual. However, mastering assembly, C, and C++ at the same time is quite challenging, and many beginners struggle significantly while learning just one of these languages. This article specifically compiles insights from … Read more
Step 1: Learning Basic Theoretical KnowledgeBasic theoretical knowledge includes analog circuits, digital circuits, and C language knowledge. Analog and digital circuits are abstract subjects, and mastering them requires considerable effort. Before you start learning microcontrollers, if you feel your foundation in analog and digital circuits is weak, do not rush into learning microcontrollers; instead, review … Read more
