这是我大学4年来做过的竞赛以及老师的科研项目所积累下来的c51源代码，一共有40多 个，心血啊！-This is my 4-year university has done the race, as well as the teacher

用MSP430F149仿真SPI接口读写FM25系列铁电的测试程序。包括单字节和多字节读写。已通过测试。请大家放心使用。-with MSP430F149 simulation SPI serial interface to read and write 25 ferroelectric testing procedures. Including single-byte and multi-byte read and write. Have passed the tests. Please rest assured use.

功能：利用时钟芯片DS12887在LCD（LCM141）上显示时间，通过4×4键盘来修改时间，利用MAXIM232进行标准串口发送。4×4键盘中有数字键（0～9）和功能键（F1键为“→”，F2键为“←”，F4键为“发送”，设置键为“设置当前时间”，确定键为“把修改的当前时间写入到DS12887相应的存储单元中”）。 硬件：单片机为8K的98C52（ATMEL），LCD为北京青云的LCM141，标准串口总线为MAXIM的232芯片，时钟芯片为DS12887（DALLAS） -Function: the use of clock chip DS12887 in the LCD (LCM141) show time, through the 4 × 4 keyboard to modify the time and using the standard serial port to send MAXIM232. 4 × 4 keyboard in numeric keypad (0 ~ 9) and the function keys (F1 key for the
