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

应用背景你好，这是一个项目告诉你如何使用与TI MSP430超声波传感器。我用MSP430G2452，然而，一G2553或任何其他芯片也会工作，但有些数字可能不同的。当然，我假设你已经知道如何使用IAR或CCS。关键技术你需要的是：MSP430超声波传感器（我有srf05，和我使用制动和其他回声一销。那里还选择在你连接模式引脚GND和只使用一个密码，但我不会那样做的你所要做的就是产生一个脉冲的长度取决于传感器，传感器。在srf05是10us。当传感器接收的脉冲，它将产生一个8次声波爆受单片机，并送回波脉冲回微控制器，我们必须测量脉冲。（对我来说太难了用词来描述整个程序，所以只需要花时间去理解代码）。从结果中得到的结果，我们只需要58。（对于任何关于传感器的进一步信息，你应该谷歌文件）。
