单片机的GPIO不够，是实际项目中最为常见的，毕竟对于老板来说，成本才是第一位要考虑的要素，那没办法，作为牛马只能多想想办法了，只不过苦了硬件和软件。 今天核桃就简单汇总一下常用的几种方案，仅供参考哈！欢迎点赞关注收藏起来！ （1）三八译码 ...

GPIO的通用性使其应用场景覆盖了嵌入式系统的所有领域，不同场景的需求差异，决定了 GPIO 的配置方式与硬件设计细节。从消费电子的 LED 控制，到工业控制的传感器连接，从汽车电子的开关检测，到物联网设备的低功耗唤醒，GPIO 的应用虽看似简单，却蕴含着 ...

GPIO的灵活性并非凭空而来，而是源于其精心设计的内部硬件结构。从引脚到芯片内核，GPIO 模块由 “物理引脚、输入输出缓冲器、复用选择器、上下拉电阻、中断控制器接口” 等部分组成，每个组件都承担着特定的功能，共同支撑起 GPIO 的通用特性。理解这些 ...

GPIO（General – Purpose Input/Output）即通用输入输出端口，是微控制器（如 STM32 系列）中非常重要的一个外设。它是一种软件可编程的引脚，用户能够通过编程来控制这些引脚的输入或输出状态。在嵌入式系统里，GPIO 引脚如同微控制器与外部世界沟通的桥梁，可 ...

GPIO端口的每个位可以由软件分别配置成8种模式。 ─推挽式复用功能 ─开漏复用功能 GPIO的模式配置均是从对应的参考手册内的GPIO章节的GPIO功能描述内的表18得到的。表内各个数值对应的内容从stm32f4xx_gpio.h文件内得到。 typedef struct { uint32_t GPIO_Pin; GPIOMode_TypeDef ...

Git isn’t hard to learn. Moreover, with a Git GUI such as Atlassian’s Sourcetree, and a SaaS code repository such as Bitbucket, mastery of the industry’s most powerful version control tools is within ...

想要掌握嵌入式系统开发中的核心技能？本文带你深入实战，从GPIO（通用输入输出接口）的基础配置出发，全面讲解输出控制、输入检测及中断处理的应用技巧。提供可直接运行的示例源码，助你快速上手，提升开发效率！ GPIO(General-Purpose Input/Output) 是通用输入 ...
