ARM汇编指令详解 （含测试题）,-ARM compilation of detailed instructions (including test questions),

这个是AM51S开发板的专用温度测试程序！-This is a dedicated development board AM51S temperature testing procedures!

把所有端口的同时置高置低,不断闪烁 2 p1 口3 路流水灯理解2 进制数与端口的关系 3 单片机的加法:把52h+0fch 结果送p1 口 4 单片机的乘法:把ff*03h 结果送p1 5 单片机的二进制加法 6 单片机的两位计数器 7 学习单片机的逻辑运算 8 进一步学习单片机的逻辑运算 9 循环移位指令的流水灯 10 理解熟悉散转结构的程序 11 位操作指令的学习 12 比较指令的学习与cy位-All ports at the same time the high home ownership low, and constantly flashing 2 p1 I 3 way light water 2 hexadecimal understanding the relationship between the number of 3-port MCU adder: the 52h+ 0fch results sent p1 mouth 4 Singlechip multiplication: ff* 03h results to send binary adder p15 SCM SCM 6 2 7 learning Singlechip counter logic operations further study 8 MCU 9 cyclic shift logic operations instructions flowing light 10 scattered understanding of familiar procedures to the structure of 11 operating instruction instructions learn learning 12 compared with the cy-bit

自己的51实习是做得数字时钟，可以调整时间，可以显示当前温度。-51 is doing his internship digital clock, you can adjust the time, you can display the current temperature.

AT45D041大容量IC卡 读写程序,不知现在还有没人用，以前我用过的一颗芯片。-AT45D041 large-capacity IC card reading and writing process, I wonder if there is no one now, and I used a single chip.

RTC8563时钟芯片的读写程序，大家共享。

功能强大的时钟中断，单片机和FIFO的接口和操作，单片机串口编程问题，纯软件单片机串口，串口通信的单片机程序，程序的多任务和资源复用举例，采用软件定时的计算方法-powerful clock interruption, the 8031 and FIFO interface and operation, the 8031 serial programming, software-only MCU, the MCU serial communication procedures, the procedures for multi-task and resource reuse, for example, regularly use the software method of calculation

P89V51RD2系列芯片是具有串口下载功能（ISP）和在KEIL中进行调试的功能（SOFTICE）。 新的芯片是ISP功能，通过FlashMagic 软件可以设置其为SOFTICE功能。 但要想回到ISP功能，则没有现成的好办法，只有通过编程器了。 但现在可以通过这个程序来恢复其ISP功能（禁止SOFTICE）。-P89V51RD2 series with the serial port chip is the ability to download (ISP) and the KEIL for debugging feature (SOFTICE). The new chip is the ISP, through FlashMagic software can be set to SOFTICE its function. However, to return to the ISP, there is no ready-made good, and that only through a programmer. But now through this procedure to restore its ISP (Prohibition SOFTICE).

用Keil uVision2编写得批量in传输程序，实现简单得数据采集，我看了觉得很有用-with Keil uVision2 prepared in bulk in transmission process, in simple data collection, I saw very useful
