基于arm的蓝牙通讯协议的设计，以实现嵌入式芯片的无线传输-Arm based on Bluetooth communication protocol design, in order to achieve the wireless transmission of embedded chip

针对三星ARM处理器的flash烧写程序，可以将二进制代码写入flash。-against Samsung ARM processor flash burning process, the binary code can be written into the flash.

本文介绍了如何用AD识别用户输入的键盘的方法，较之点阵识别有其不可替代的优势；因为如果用4*4的话须消耗8个I/O口，而如果系统有AD功能的话就可能轻松解决了。 单片机8051F330发给ARM然后发给电脑。 其原理就是利用电阻的分压，按键时产生不同的电压，再用中断快速读取电压；然后对其进行编码，通过串口软件EASYARM在个人电脑里显示；经实验观察，效果还可以。 -This article describes how to use AD to identify the user s keyboard input methods, compared with dot-matrix recognition has its irreplaceable advantages because if we use 4* 4, then to be consumed eight I/O port, and if the system function in AD, then on may be easily resolved. Singlechip 8051F330 distributed computer and then distributed to ARM. Its principle is to use the sub-ballast resistor, when keys have different voltage, and then quickly read voltage interruption then encode, through the serial port software EASYARM in the personal computer display by experimental observation, the effect can also be.

EasyARM2104开发套件实时时钟测试源代码。-EasyARM2104 Boards Real Time Clock test source code.

这是 nrf24le1 从沙伦球和 SDCC sdk 的示例代码。 客户端和服务器。

从ucos官网下载的ucosiii 工程，然后从iar移植到codewrrior10.5中，同时修改了bsp包中pll初始化，基于100M的时钟频率。以及中断和开始代码的修改。

其中不仅带有基本的收发测试程序，还有关于nrf905所有的基本资料。是学习905的必备。。。。
