铁电存储器读写，I2C时序。适合工业用的存储器，本程序实现了底层驱动，读写以及部分文件系统。

使用89S52设计的电子钟，C51 编写，本例没有使用1302等时钟芯片，但本例完全具有时钟芯片的功能。比如基本的年月日，时分秒和星期功能，而且还有平闰年的天数自动补偿。由于采用的是全软件算法，时钟误差较大，采用高质量晶振可以减少误差。本例重在培养与训练初学者对C51的学习。-89S52 designed using an electronic clock, C51 preparation, in this case did not use 1302 clock chip, etc., but in this case complete with a clock chip functions. For example the basic date, time, and every second week of features, but also the number of days flat leap automatic compensation. As a result of the full software algorithms, the clock error of greater use of high-quality crystal can reduce the error. In this case focuses on training and training for beginners to learn on the C51.

成功的最新测试tslib，运行在RMI AU1200哦！！很难得到它！！

1. SH1106显示屏是132*64的寄存器，操作时请按照132*64来操作，    若按照128*64操作，屏幕右侧的边缘会出现一条亮线。     2. 这款屏是CMOS兼容TTL工艺的，理论上3.3V~5V都可以使用，但建    议使用3.3V，这样会大幅提高OLED的寿命。

本程序是MP3的解码程序，可以用VC编译或者用GNU编译，可以运行在PC机上。 本程可以MP3文件解压为WAV文件 TEST 中的代码可以播放WAV文件 有兴趣的朋友可以把这段mp3程序移植到开发板上，这样就可以用开发板播放MP3了-MP3 decoding procedures that can be used with VC or GNU compiler compiler. can run on the PC. The process can decompress MP3 to WAV TEST document of the code can be broadcast WAV documents are interested friends this can be transplanted to mp3 development board, we can develop with the board to broadcast MP3
