单片机编程 PIC单片机的RS232通讯程序
Digitemp Jr. is a device that is designed to measure
and report ambient temperature. When connected to
an RS-232 port on any PC, it will periodically measure
and report in ASCII form the ambient temperature in
degrees Celsius. These temperature readings can be
monitored with any terminal program. If ...
单片机编程 基于MC9S12HZ256的总线式汽车数字仪表设计
首先研究CAN总线和SAE J1939协议，提出一种基于MC9S12HZ256微控制器的总线式汽车数字仪表解决方案。详细介绍SAE J1939协议的报文帧格式及应用层协议中发动机相关参数的定义，以及步进电机及其驱动和车速信号的处理方法。该数字仪表系统硬件平台由微处理器和信号采集和信息处理及显示等模块组成。软件设计部分编程实现了对CA ...
单片机编程 基于C8051F020的通用串口适配器的设计
介绍了基于单片机C8051F020的通用串口适配器的设计与实现方法，即由单片机控制的智能化一对多口收发信号转换器。通过采用C51对单片机进行编程，控制与RS-232（标准RS-232电平）、RS232(TTL电平)、RS-422接口的数据通信；采用C++ Builder作为开发平台，通过RS-232接口实现上位机对适配器各个通信端口的控制。
