单片机编程 单片机P0口的片外数据存储器扩展
单片机作为一种微型计算机，其内部具有一定的存储单元（8031除外），但由于其内部存储单元及端口有限，很多情况下难以满足实际需求。为此介绍一种新的扩展方法，将数据线与地址线合并使用，通过软件控制的方法实现数据线与地址线功能的分时转换，数据线不仅用于传送数据信号，还可作为地址线、控制线，用于传送地址信号和控 ...
单片机编程 基于PIC单片机的脉冲电源
基于PIC单片机的脉冲电源:设计了一种金属凝固过程用脉冲电源。该电源采用PIC16F877作为主控芯片，实现对窄脉冲电流幅值的检测，以及时电流脉冲幅值根据模糊PID算法进行闲环控制。使用结果表明：该电源的输出脉冲波形良好，电流幅值稳定，满足合金材料凝固过程的工艺要求且运行稳定可靠。关键词：脉冲电源；PIC16F877单片机 ...
单片机编程 USB Demonstration for DK3200 w
The μPSD32xx family, from ST, consists of Flash programmable system devices with a 8032 MicrocontrollerCore.
