Project Objective Following the successful implementation of PWM-based breathing light effects, the next phase involves expanding the user interface capabilities of the XR806 development board. To achieve richer information display, a TFT LCD module is integrated using the hardware SPI peripheral. This guide details the wiring, driver adaptatio ...

Memory alignment in C structs governs how data members are positioned in memory relative to address boundaries. This behavior directly impacts memory footprint, cache efficiency, and hardware-level access correctness—especially on architectures that enforce strict alignment (e.g., ARM64 or older SPARC). Unlike high-level languages, C exposes th ...

1. Memory and Bus Architecture The STM32 architecture is built around a multi-layer bus matrix that facilitates communication between the Cortex-M3 core and various peripherals. Key components include: I-Code Bus: Fetches instructions from the Flash memory. D-Code Bus: Accesses data (constants) in Flash or variables in SRAM. System Bus (S-Bus) ...
