Microcontroller:Architecture, Assembly Language, and Hardware Interfacing Book: Main | Synopsis | Table of Contents | Errata/Corrections Introduction "The 8051/8052 Microcontroller: Architecture, Assembly Language, and Hardware Interfacing" was written by Craig Steiner, the webmaster and author of 8052....
certain key functions must first be established. The first function created must be the "delay" function which is integral to all read and write control. This function will be entirely dependent the speed of the microcontroller. For this example, a DS5000 (8051-compatible) microcontroller running...
在本应用笔记提供的示例中,软件子程序每秒一次连续读取32位秒计数器的数值,并通过8051微控制器(µC)的UART接口以ASCII码格式输出时间和日期。时间和日期基于从1970年1月1日,00:00:00起所经历的时间,单位为秒。00000000h对应的时间是1970年1月1日,00:00:00;42C924C0h对应的时间为2005/7/4 12:00:00。
本应用笔记介绍了DS1305串行实时时钟(RTC)与8051微控制器的接口方式,所提供的程序代码能够实现基本的接口功能。本文所采用的微控制器是DS2250柔性微控制器模块,程序用C语言编写。该程序能够演示时间、日期的设置和读取,RAM的读、写操作以及闹钟的设置和读取。 工作原理 接口程序利用微控制器的三个通用端口与DS1305...
real time clock interfacing with 8051 microcontroller using I2C bus protocol. I2C is a bi-directional serial protocol, which consist of two wires such as SCL and SDA to transfer data between devices connected to bus. 8051 microcontroller has no inbuilt RTC device therefore we have connected extern...
through this route the control signals are transffered to the LCD module. Resistor R1 limits the current through the back light LED and so do the back light intensity. POT R2 is used for adjusting the contrast of the display. Program for interfacing LCD to 8051 microcontroller is shown ...
