Previously, I shared a document-based tutorial on creating an SPI Flash programming algorithm. However, feedback from users indicated that it was not very convenient to port to other microcontrollers. This post is created to facilitate the migration to various platforms. Application scenarios for the SPI Flash programming algorithm: 1. In an IDE environment, such as … Read more

Introduction More and more products on the market have safety requirements regarding their use. How to avoid danger to operators during use or reduce the probability of such dangers occurring is a key consideration for product safety. In this regard, related products need to pass safety certifications from relevant industries before they can be produced … Read more
1. Introduction to SPI SPI, short for Serial Peripheral Interface, is a serial communication interface defined by Motorola for its MC68HCXX series processors. The SPI interface is mainly used between EEPROM, FLASH, real-time clocks, AD converters, as well as digital signal processors and digital signal decoders. SPI is a high-speed, full-duplex, synchronous communication bus that … Read more

With the development of the Internet of Things (IoT), microcontrollers have become even more prevalent in … Read more
Welcome FPGA engineers to join the official WeChat technical group Clickthe blue textto follow us at FPGA Home – the best and largest pure FPGA engineer community in China Non-volatile storage components come in many forms, such as EPROM, EEPROM, NOR FLASH, and NAND FLASH. The first two have basically been phased out, so I … Read more
I'm Lao Wen, an embedded engineer who loves learning. Follow me to become even better together! Memory is divided into two main categories: RAM and ROM, and this article primarily discusses ROM. Initially, ROM could not be programmed; it retained whatever content it was manufactured with, making it inflexible. Later, PROM was introduced, which could … Read more
01 Preparation Work To flash the ESP32 application program using a serial port in a virtual machine, you must first ensure that the serial port of the development board can be correctly connected to the virtual machine. The virtual machine software I am using is VirtualBox 6.0. When the development board is connected to the … Read more
1. Linker Script Ld 1.1 Load Address LMA and Run Address VMA 1.1.1 Load Address LMA When programming, the addresses where the code segment and data segment are stored are generally in FLASH. This storage address ensures that data is not lost when power is off. 1.1.2 Run Address VMA During software execution, the (virtual) … Read more
