超声波测距，能够实现汽车防撞系统超声波的测距，完全由51单片机控制(Ultrasonic Ranging)

AES128/196/256 加解密源码，可实现ECB模式加密，HEX输出。密码及明文没有补齐功能，需手动补齐。无需特殊库文件，适合单片机使用。已测试，可正常使用。(AES128/196/256 encryption source code, can achieve ECB mode encryption, HEX output. The password and the plaintext without the need to manually fill up function. No special library files, suitable for single use. Has been tested, can be used normally.)

说明：  51单片机的拼音输入法的程序，用C实现，(51 SCM Pinyin input method to the procedures used to achieve C,)

这段代码包括了基于STM32对简单小车的循迹壁障以及L298N的驱动。并对其中关键部分进行了注释。(This code includes a simple car-based STM32 tracking barrier and L298N driver. And one of the key parts of the notes.)

1. 本研究利用 PCA 对可见-近红外（450～1 000 nm）、可见光（450～780 nm）和近红外（780～1 000 nm）光谱区域的苹果高光谱图像数据进行降维，获得 PC 图像，通过对 PC 图像进行分析，确定可用于分割损伤和正常区域的有效光谱区域，对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and dirt stains exists. In order to obtain maximum throughput, processing speeds of over 85,000 eggs per hour are common. The demanding requirements placed on the human workers result in two types of grading errors)
