What is DAPLink?DAPLink (full name Arm Mbed DAPLink) is essentially a “small brain” that runs on a development board and is specifically responsible for “handshaking” with the computer. It is installed on a secondary MCU, connected to the main MCU’s SWD/JTAG port, and then bridges the computer, debugger, and programmer via USB. In other words, … Read more
In the world of 3D printing, hardware varies greatly, with a wide range of motherboards and inconsistent protocol standards. Achieving harmonious coexistence among all devices is not an easy task.Compatibility differences and configuration complexity have become the biggest obstacles to the widespread adoption of 3D printing. The emergence of Marlin firmware has completely changed this … Read more
In embedded system development, “Firmware” and “Software” are two concepts that are closely related yet fundamentally different. They together constitute the operational logic of a device, but they have clear boundaries in terms of hardware dependency, functional positioning, and development models — firmware is the “soul of the hardware,” responsible for bringing the hardware “to … Read more
Follow+Star PublicAccount, don’t miss out on exciting content Source | Network 1. Introduction Embedded firmware is generally divided into BootLoader and App. The BootLoader is used for startup verification, App upgrades, and App version rollbacks. The BootLoader runs during the first phase of CPU power-up and then jumps to the App address to execute the … Read more
In microcontroller development, HEX and BIN files are like a “dual-track train” for program transmission—the former comes with address tags and checksums, while the latter is a pure binary data stream. Understanding the core differences and applicable scenarios of both is key to avoiding programming errors and optimizing storage space. 1. Essential Differences Pointing to … Read more
Flip-card is a project that combines hardware design (using Raspberry Pi RP2350 as the main controller, 21*22 LED matrix) and software implementation, aimed at displaying fluid simulation (FLIP) effects through a business card-sized device. This project utilizes existing fluid simulation algorithms (FLIP) and hardware design, achieving high-performance firmware implemented in the Rust programming language, with … Read more

MediaTek today released an important security announcement addressing multiple vulnerabilities in its latest modem chipsets and urged device manufacturers to deploy updates immediately. This announcement comes two months after confidential notifications were sent to manufacturers, confirming that no exploitation of these vulnerabilities has been observed in the wild.Part01 Key Points MediaTek has patched high and … Read more
Programming UFS Chips From a structural perspective: Although there is no significant difference in appearance and function between eMMC flash memory and UFS flash memory, the internal structures of the two are fundamentally different. This essential difference in internal structure leads to a significant disparity in their theoretical bandwidth. Overview of UFS Chips Definition UFS … Read more
