基于FPGA的远程实体操控单片机实验平台开发
<p>传统单片机实验教学大多采取现场实体操作模式,受时间和空间约束较大,学生对课程预习与复习均缺少一种相对便利的方式。因此,针对实际教学中遇到的问题,设计并开发了基于FPGA的远程实体操控单片机实验平台。该平台使用FPGA对底层结构进行搭建,实现了远程连线、现场跟连、远程下载实体实验箱程序、远程观看实体实验箱波形等功能,具有时空开放、资源优化、虚实结合的崭新特点,能够弥补传统实验教学设备的不足,对
基于单片机的城市路灯节能控制系统
<p>为缓解电力资源紧缺现状,将城市照明能耗降低至标准限定额度以下,提出一种基于单片机的新型城市路灯节能控制系统。在层级式控制架构中,设置STC15F2K60S2型号的单片机主控芯片,并利用外界传输信道,连接唯一的射频调节模块,完成新型城市路灯节能控制系统的硬件运行环境搭建。在此基础上,连接ZigBee传输协议,并在传递节能控制信号的过程中,建立完善的单片机网络组织,实现系统的软件运行环境搭建,结
基于MSP430单片机的FED点阵汉字显示软件设计
<p>本设计旨在有效推动场致发射显示器(FED)产品化与市场化。采用MSP-EXP430G2单片机作为FED的驱动芯片,用TCA6416A芯片对单片机引脚进行扩展,将串行数据转换为16位的并行数据作为点阵显示电路的行驱动,再用译码器对I/O口编码,从而选定FED点阵的列数用于列驱动,最后成功的实现了16×16的FED点阵字符的动态显示。将一次完整扫描时间控制在20ms以下,且每行扫描持续时间设置为
