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.)

采用TI LaunchPad开发板触摸屏控制DAC7611输出电压(TI LaunchPad development board using the touch screen controls DAC7611 output voltage)

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)
