一个日历时钟DS12887或146818的C语言源程序

应用背景主要应用于51单片机的SD卡操作，完美适用于STC12c60s2单片机，现在的这方面的资源比较少，适用于51的更少，所以如果有需要这方面的资源，可以参考下，个人觉得很不错，已调通。关键技术51单片机的SD卡操作，完美适用于STC12c60s2单片机，函数有点大，住要是ZNFAT.C文件，里面是文件系统的主要函数，不过有些函数还未有待实验，SD.H文件的4个引脚可以根据自己的单片机自己定义，串口函数波特率为2400；

基于51单片机平台，用ds1302显示万年历，可以按键设置时钟。本程序用c语言编写，比较简单，仅供新手熟悉单片机编程的基本格式。

The objective is to set up SPI communication between VTI Technologies digital pressure sensor component and an MCU of an application device ATMEGA16L. In this code example: ?The MCU is configured ?SCP1000-D01 is initialized and configured ?The high resolution measurement mode is activated ?Temperature and pressure information is read always when the DRDY pin is in high state Please refer to the document "SCP1000 Product Family Specification 8260800" for further information on SCP1000 register addressing and SPI communication.
