介绍针对dsPIC33FJ32MC204或同系列单片机使用入门。1、开发环境选择开发环境:MPLAB IDEV8.80编译软件:MPLABC30,其中v3.25版本C语言编译器 pic30-gcc.exe,见下图。尝试过使用最新开发环境MPLABXIDEV1.95配合数种编译器均无法对程序编译通过。...
PLC系统可实现与单片机之间的串行通信,这一组合方式在工业自动化控制技术领域中非常常见且具有重要地位。当然,串行通信应用问题本身也是自动控制系统设计的重要难点。本文希望首先了解PLC与单片机相关理论概念与串行通信特点,然后对二者之间的串行通信技术应用流程进行深入研究分析。The PLC system...
SATA(Serial ATA)是一种高速的串行总线,采用点对点方式进行数据传输,内置数据/命令校验单元,支持热插拔,具有150MB/s(SATA 1.0)或300MB/s(SATA 2.0)传输速度。目前SATA应用广泛,但国内尚无独立研发的SATA芯片。 分析了SATA协议标准,建立了SATA主...
