发光二极管显示动态扫描表面51单片机

基于keil开发平台，在stm32上实现led的秒闪。程序能够成功运行，实现led秒闪功能。   程序部分代码摘录： void LED_GPIO_Config(void) {     /*定义一个GPIO_InitTypeDef类型的结构体*/   GPIO_InitTypeDef GPIO_InitStructure;   /*开启LED的外设时钟*/   RCC_APB2PeriphClockCmd( RCC_APB2Periph_GPIOD, ENABLE);   /*选择要控制的GPIOB引脚*/            &n

这是支持MF RC500 MIFARE 读写集成电路IC的有关射频设计的应用笔记。意在提供对MIFARE 射频接口（ISO 14443A）所需的理解来设计具体天线应用和匹配电路，为了使无接触MIFARE卡通信有最优表现。本文给出了系统的RF部分背景，以及如何为标准应用设计和调试天线的过程概述。详细说明了两种不同的天线和匹配概念以及它们的设计实例。还描述了完整的调试天线的步骤。作为附件的一部分，有兴趣的读者会发现RF接口的详细理论描述-This is to support reading and writing IC MF RC500 MIFARE RF IC design of the Application Notes. Intended to provide MIFARE RF Interface (ISO 14443A) designed to understand the requirements of specific applications and antenna matching circuits, in order to make contactless MIFARE cards have the best communication performance. In this paper, the RF part of the background of the system, as well as standard application for the design and debugging process of an overview of the antenna. Detailed description of the two different concepts of antennas and matching, as well as their design. Also a complete description of the steps to debug the antenna. As part of the annex, interested readers will find the detailed theory of RF Interface Description
