1. Company HistoryThe story of Gigadevice began in 2005, born in Beijing’s Zhongguancun. Its start was not in the hottest fields of general-purpose processors or memory, but rather it astutely chose the relatively overlooked niche market of NOR Flash as its breakthrough point. With solid technical accumulation and precise market judgment, the company quickly grew … Read more
We plan to explain how to design and write your own Bootloader for STM32 devices.Before we start writing code, we must first understand what a Bootloader is and why it is needed.This article will introduce you to the basic concepts of Bootloader. Bootloader Basics A Bootloader is a very important component of any operating system. … Read more
1. What is an MCU? Embedded Microcontroller (MCU, Microcontroller Unit) is a highly integrated chip-level computer designed for embedded systems. It integrates functions such as a Central Processing Unit (CPU), memory (RAM/ROM/Flash), input/output interfaces (I/O), timers/counters, and communication modules (such as UART, SPI, I2C) onto a single chip, characterized by high integration, low power consumption, … Read more
Recently, a student asked me: “How many SPI chips can I connect to my 51 microcontroller board? Is it not mentioned in the chip manual, or did I miss it? Moreover, I want to connect a screen, a memory card, a temperature sensor, and a wireless module.” Today, let’s discuss this topic. First, let’s talk … Read more
1. Demand Differences: The “Personalization” Challenge of Microcontrollers In the world of microcontrollers, there is no “one-size-fits-all” solution. Imagine if a restaurant only offered one family-style meal; could it satisfy all diners’ needs? Clearly not. Similarly, the applications of microcontrollers vary widely: some projects require ultra-low power consumption, while others pursue high performance; some interfaces … Read more
Recently, Renesas Electronics announced the launch of the RA0L1 microcontroller (MCU) product line based on the Arm® Cortex®-M23 processor. The RA0L1 microcontroller operates with a mode current as low as 2.9mA and a sleep mode current of only 0.92mA. Its fast wake-up feature reduces standby power consumption to 0.25μA, achieving a 90% reduction compared to … Read more
In microcontroller programming, many people can complicate issues that seem simple, creating a mess akin to a spider web in a forest. In fact, according to the philosophy of programming magic, strictly dividing the process of program handling into departments, each performing its own duties, and ensuring that departments do not interfere with each other’s … Read more
Abstract This article discusses the definition of EMC, testing methods for microcontroller application systems, the application of new EMC devices and materials, and troubleshooting techniques. Anyone involved in the research, development, production, or supply of electronic products must conduct EMC electromagnetic compatibility testing. Introduction EMC, or Electromagnetic Compatibility, refers to the ability of a device … Read more
Microcontroller programs are familiar to everyone, but few truly consider the architecture used. As program development continues to increase, having a solid architecture becomes essential. 1. Time-Slice Polling Method This is a program architecture design scheme that lies between sequential execution methods and operating systems. This design scheme aims to help embedded software developers elevate … Read more
