用VC++编程实现对CPU主频的检测

应用背景px4程序可以运行固定翼，旋翼等飞行器，而且是很多人再开发，有很多有用的算法，如扩展卡尔曼滤波，迭代法等等。可以GPS定位，GPS下走航点等等，希望能帮到大家关键技术C++编程，扩展卡尔曼滤波，IIC读取超声波，读取气压计。室外光流能很好定位，能用于固定翼，旋翼，而且可以二次开发，支持offboard模式。

This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It permits you to download new code to the device over USB. This bootrom is installed at address 0x00000000 in the ARM, which means that it is the first piece of code to execute after reset. At startup, it waits for a few seconds to see if the downloader is trying to connect. If not, then the bootloader gives up control and jumps to your program. If the downloader is trying to connect, then the bootloader receives the new program over USB and writes it into flash.

这是本人做的模数转换，分为四个模块，最终输出为两个信号的4位二进制结果，其中采样后的为补码，所以本人转化为原码。这些模块可以根据需要更改。
