二次开发

本套代码的硬件环境是匿名领航者飞控，十分适合大家做二次开发。本代码是2017年电赛我们团队开发的，能实现自主起飞定点定高，跟踪循迹等，在电赛C题的功能均能实现，我们团队也获得2017年电赛全国一等奖。此代码独立性很强，接上接收机连上遥控器就能遥控起飞，经过修改优化，遥控手感更好。也可以自动起飞，模式可以通过串口通信自由切换，协议简单。但是请飞友们注意，一定要注意安全。

椭圆曲线的实现(ECC)，椭圆曲线算法是代数几何、数论等多个数学分支的一个交叉点，一直被人们认为是纯理论学科。而椭圆曲线密码体制，是基于椭圆曲线离散对数问题的一种公钥密码体制(Realization of elliptic curves (ECC), elliptic curve algorithm is algebraic geometry, a number of mathematical intersection of number theory and other branches, has been considered a purely theoretical discipline. The elliptic curve cryptosystem is based on elliptic curve discrete logarithm problem as a public-key cryptosystem)
