ARMSYS实验二十四：FAT16文件系统的移植与应用 描述：对Nandflash进行格式化，完成文件系统初 始化，并利用FAT16提供的API函数进行文件操作。 另有：flash_tools，观察nandflash扇区内容的工具-Experimental ARMSYS 24: FAT16 file system and application of transplantation Description: on the NANDFLASH format, the completion of the file system initialization, and use the API provided FAT16 file operations function. Otherwise: flash_tools, to observe the contents of the NANDFLASH sector tools

资源描述FatFs是一个通用的文件系统模块，用于在小型嵌入式系统中实现FAT文件系统。 FatFs 的编写遵循ANSI C，因此不依赖于硬件平台。它可以嵌入到便宜的微控制器中，如 8051, PIC, AVR, SH, Z80, H8, ARM 等等，不需要做任何修改。

/*温控系统实现功能要求：1在前三个数码管上显示 当前采集到的温度（0-99.9）2当环境温度低于27°c时，蜂鸣器开始以慢"滴"声报警，并且伴随p0.0口发光二级管闪烁（模拟开启制热设备）；当环境温度继续降低并低于25°c时，蜂鸣器以快‘滴’声报警，并且伴随p0.0和p0.1口发光二极管一起闪烁（模拟加大制热设备功率） 3当环境温度高于30时，蜂鸣器以慢‘滴’声报警，并且伴随p0.2闪烁（模拟开启制冷设备）；当环境温度继续升幅并高于32时，蜂鸣器以快‘滴’声报警，并伴随p0.2和p0.3二极管一起闪烁（模拟加大制冷设备） 4用串口将采集的温度数据实时发送给上位机，在上位机软件上显示当温度值*/ //将p2.4和138的j22的1连接
