许多应用程序通常使用emcpy（）C库函数将大量数据从一个内存区域复制到另一个内存区域。由于这可能相当耗时，因此花一些时间优化执行此操作的函数可能是值得的。

采样模拟信号，转化成数字信号。 2）接口的连接问题。 3）LED显示器如何接入电路。 4) 如何进行显示控制。 -Sampling analog signals into digital signals. 2) interface connectivity problems. 3) LED display to access the circuit. 4) How to display control.

一个垃圾压缩车的PLC程序。采用X端口作为模拟量转换后的数据量输入口。这种方法不需要买模拟量模块，1000块就省下来了！-A garbage truck PLC compression procedures. X-port analog conversion, as the amount of data input. This method does not need to buy analog module 1000 on the savings!

每次开机都将次数加1 并存储到EEPROM。这样就能直观的看到机器的使用次数。用P1口 LED做为显示，次数大于256是将溢出，按复位模拟开机 或者直接通过开关开机。-Each boot will add a number of times and stored in EEPROM. This will be able to see the intuitive usage of the machine. As with the P1 port LED display, frequency is greater than 256 is the overflow, according to reset the boot, or directly through the analog switch boot.

该资料是教你如何编写nRF2401无线通信的教程，写的很不错。我写个程序就是根据它改进的！-The information is to teach you how to write nRF2401 wireless communication tutorials, written very well. I write a program that is based on its improved!
