段码液晶 显示资料，资料很全，-Code segment liquid crystal display of information, information is very wide,

本示例描述如何使用 ADC3 和 DMA 传输不断 转换后的数据从 ADC3 到内存。 ADC3 配置为连续转换 channel7。 每次转换结束时的 DMA 传输，在循环模式中， 转换后的数据，ADC3 博士从注册到 ADC3ConvertedValue 变量。 在此示例中，系统时钟是 144 兆赫，APB2 = 72 兆赫和 ADC 时钟 = APB2/2。 由于 ADC3 时钟是 36 兆赫和采样时间设置为 3 个周期，转换 12 位数据的时间是 12 个周期，所以总转换时间是 (12 + 3） / 36 = 0.41us(2.4Msps)。

README for TinyECC Version 2.0 Author/Contact: An Liu, liuan79@gmail.com Introduction ------------ TinyECC is a software package providing ECC-based PKC operations that can be flexibly configured and integrated into sensor network applications. It provides a digital signature scheme (ECDSA),  a key exchange protocol (ECDH), and a public key encryption scheme (ECIES). It provides a number of optimization switches, which can turn specific optimizations on or off based on developer"s needs. TinyECC 2.0 supports MICA2/MICAz, TelosB/Tmote Sky, BSNV3, and Imote2 motes. It supports SECG recommended 128-bit, 160-bit and 192-bit elliptic curve domain parameters. How to install -------------- 1) Install TinyOS 2.1.1 or later version. ht
