Have you ever experienced the painful moment of losing a PPT you spent half a day editing because you forgot to click save? The saving process we are talking about here is closely related to the application of storage chips introduced in this article. What is a storage chip? In the information age, the demand … Read more
CPU Section 1. CPU Architecture The CPU architecture currently lacks a definitive and authoritative definition. Simply put, it refers to the design scheme of the CPU core. CPUs can generally be classified into various architectures such as X86, IA64, RISC, etc. The CPUs found in personal computers are essentially designed based on the X86 architecture, … Read more
Generally, ROM is used to store firmware, while RAM is used to hold data. Since FLASH ROM has faster read and write speeds and is easier to erase compared to ordinary ROM, it is typically used to store user programs and data that need to be permanently saved. For example, the core of a household … Read more
Bus: Refers to the information transmission line that serves multiple components. In microcomputer systems, various components communicate with each other through the bus. Address Bus (AB): The address bus is unidirectional and is used to transmit address information. The width of the address bus is 16 bits, thus allowing direct addressing of 64K external memory. … Read more

FPGA is a product further developed based on programmable devices such as PAL, GAL, EPLD, and CPLD. It emerged as a semi-custom circuit in the ASIC field, addressing the shortcomings of custom circuits and overcoming the limitations of existing programmable logic gates. Since FPGAs need to be rewritten repeatedly, their basic structure for implementing combinational … Read more
The LCDs we purchase generally consist of two parts: The LCD panel and the LCD driver chip Our processor does not directly drive the LCD panel, but rather drives the LCD driver chip, which in turn drives each pixel on the LCD panel. Therefore, to make the LCD display certain content, we need to consider … Read more
Hello everyone, today I am sharing an article about a microcontroller program framework. 1. Importance of Program Framework Many people, especially beginners, often write code without an overall plan, leading to increasingly messy code and constant bugs. Eventually, the code seems to run fine (it might actually be fine), but when adding a feature, a … Read more
Introduction It is common for users of KEIL to encounter the issue of needing to run part or all of the program code in RAM. This article summarizes several methods to run programs in RAM using an example from the STM32F411 Nucleo. We will start with the ToggleLED function executing in Flash. Below is the … Read more
