本文以51单片机为例介绍如何扩展USB接口进行对U盘的读写，并详细介绍FAT16、FAT32文件系统的细节以及如何编码实现单片机对文件系统的常用操作，顺带提到一点关于U盘兼容性问题的解决经验。在这里单片机是host，U盘是slave。-In this paper, single-chip microcomputer 51 as an example on how to expand the USB interface on the U disk read and write, and details on FAT16, FAT32 file system and how to encode the details of the realization of single-chip microcomputer used for file system operations, mentioned in passing that on U disk experience compatibility problems. Here is a single-chip host, U disk is a slave.

* The keyboard is assumed to be a matrix having 4 rows by 6 columns. However, this code works for any * matrix arrangements up to an 8 x 8 matrix. By using from one to three of the column inputs, the driver * can support "SHIFT" keys. These keys are: SHIFT1, SHIFT2 and SHIFT3.
