应用背景Logical separation of program and data memory All 8051 devices have specific memory organization, they have separate address spaces for Program (ROM) and Data (RAM) Memory. This logical separation of Memory is useful because it allows the Data Memory to be accessed by 8-bit addresses, which can obviously be more quickly stored and manipulated by an 8-bit CPU. Of course, the l6-bit Data Memory addresses can still be generated with the DPTR register. Program Memory Program Memory can only be read, not written to. The address space for 8051 core is 16- bit, so there is maximum of 64K bytes of Program Memory. Up to 4 Kbytes of Program Memory can be on chip, internal Program Memory of the 8051 core. For access to external Program Memory is used signal PSEN (Program Store Enable). Data Memory Data Memory is on a separate address space than Program Memory. For external Data Memo

单片机51系列的串口通信例程,良好的模块说明.使你更容易全面掌握串口通信的操作.内部含相应的数码管操作.-51 series single-chip serial communication routines, a good description of the module. Make it easier for you complete control of the operation of serial communication. Internal with the corresponding digital control to operate.

用ISD1700来实现读温度，比如27.5摄氏度，先分段录制声音：1,2,3,4,5,6,7,8,9,十，点，温度，摄氏度。读27.5摄氏度时，再分段找地址，读出相应的数-Reading used to achieve ISD1700 temperature, such as 27.5 degrees Celsius, the first sub-recording the voices of: 1,2,3,4,5,6,7,8,9, ten, point, temperature, degrees Celsius. Reading of 27.5 degrees Celsius, then find a sub-address, read out the corresponding number of

该程序完成了c8051外围电路的驱动和串口协议的编写。希望能给大家学习51单片机带来帮助-The program was completed C8051 driver peripheral circuits and serial protocol to prepare. I hope everyone can learn from 51 Singlechip help
