This article explains how to adopt Linux kernel's struct‑array initialization and device‑tree matching techniques to implement a flexible C‑based UART driver that supports multiple compression configurations, complete with code examples and compilation guidance.
This tutorial explains how to use the YS‑IRTM NEC infrared codec module with an STM32F103C8T6 MCU to decode remote‑control signals, map them to UART commands, and drive a three‑color LED, covering hardware wiring, protocol details, UART configuration, and full source code.
This article explains the purpose, operation modes, configuration parameters, and register-level setup of DMA in STM32 microcontrollers, illustrating how DMA offloads data transfers from the CPU, improves performance, and provides concrete code examples for UART and memory‑to‑memory transfers.
This article explains several practical techniques for printing debug logs in embedded development—using SRAM buffers, SWO trace, UART with DMA, and GPIO‑bit‑banging—detailing their implementation, advantages, limitations, and code examples for reliable diagnostics on chips lacking conventional serial interfaces.
This guide explains the design, architecture, and step‑by‑step usage of an AT command parsing library for bare‑metal and OS‑based systems, covering job queue management, core APIs, example code, and integration with modem, Wi‑Fi, and Bluetooth modules.
This tutorial shows how to wire a three‑color LED to an STM32F103C8T6, configure a HC‑08 Bluetooth module for UART communication, and write C code that toggles each LED based on received keywords (green, yellow, red) using the STM32 HAL library.
This tutorial walks you through downloading the source, understanding HC‑08 specifications, wiring the module to an STM32F103C8T6 board, using AT commands to configure roles, power modes, and connections, and implementing UART‑based send/receive code to enable bidirectional communication with a mobile app.
