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

利用Nios Ⅱ软核处理器，以Altera公司的UP3开发板为硬件平台，以Quartus II、Quartus ID为软件开发平台，设计一个电子钟，实现下列系统功能： （1）在液晶屏上显示时间、日期、状态提示； （2）利用4个按键对时间（时分秒）、日期（年月日）进行设置； （3）利用一个LED灯指示当前设置状态；-The use of soft-core processor, Nios Ⅱ to Altera s UP3 development board as the hardware platform to Quartus II, Quartus ID for software development platform, design a clock

2812使用spi读写fm25cl64或者at25640的程序，已经测试通过。注意在在eeprom的datasheet中都写只支持spi的0或者3模式，但我用0模式一直调不通，改用spi模式才可以，程序中就是使用spi的1模式。-2812 to read and write using spi or at25640 procedures FM25CL64 have the test. Attention to the datasheet in the EEPROM are write only support spi mode 0 or 3, but I used the 0 model has been adjusted barrier before they can switch to spi mode, process is the use of one mode of spi.
